I'm replacing a motherboard for a HP laptop. I need to replace this backplate for the CPU heatsink to the new motherboard. I've tried to pull it out but it seems to be glued onto the motherboard.
If I manage to pull it out, should I replace the glue, double-sided tape or whatever is underneath?

HP G62-b80SS laptop.
Intel Core i3 CPU.
Thank you

A:How can I remove/replace this CPU heatsink backplate (where the CPU socket is screwed)?

It is probably double stick tape used to insure it stays in place. Replacing it is your call. As long as the heatsink is mounted correctly, it really doesn't matter if the backplate is loose or stuck in place. Sticking the backplate simply makes mounting the heatsink easier to manage.

My acer battery was getting bad and my computer suggested I change it. Now with my charger plugged in(with or without battery) my laptop will power down after 15-20mins. I have ordered a new battery and will try it but I would have thought my laptop should run fine without one plugged in? Any idea the cause of this?

My Dell has been acting up pretty recently (6 months old and still under warranty), and the battery does not charge past 80%. Once it get's near the 80% charge, it immediately fills up to 100%.

I've remembered using the laptop for more than 6 hours under moderate use but now it barely lasts 2 hours.

Please give me some advice because I'm really dependent on this laptop.

I currently have 2 x 4GB sticks to equal 8GB but I want to upgrade to 16GB total. Initially I was going to buy the same 2 x 4GB sticks again since I have 2 RAM slots spare, but then I read about dual channel/quad channel etc and basically want to know if it would be better to add 2 more 4 GB sticks, or buy 2 x new 8GB sticks. Thinking performance wise, the price isn't too different.
I have MSI Z77A-GD55 mobo, and my RAM is Kingston 8GB 1600MHz DDR3

Thanks in advance for advice

A:Upgrading my RAM, better to add, or replace?

For DDR3 there is no quad channel, either way would work fine, go for the cheaper.

I have an old router. It's a D-link DIR-625. Lately it seems like browsing on my laptop and tablet have been sluggish. Could it be wearing out or has technology passed it by? I'm wondering if I should replace it.

A:When to replace a router

There are numerous other things that could effect Internet traffic. Of the most common in my area is bad service from ISP (bad lines or equipment).

Resetting your router could help if it is the router causing the issue. Simply unplugging it is not enough to do a full reset of all settings.

What does running state your connection rate is and does it match what you are paying for?

I've been having an issue which started this morning. The previous night, I forgot to plug in my Dell Inspiron N5050 after using it. I woke up to find that my battery had died (obviously). I plugged in the laptop, running Windows 7 HE 64 bit, and turned it on. It booted normally and I was able to do all of my tasks as needed. Then I noticed my problem. The battery icon down on the taskbar showed that the device was plugged in, but was not charging. It has stayed at a constant 2% charge for more than 24 hours now. The Battery Meter stated that my battery is performing normally, so I ruled the battery out as the cause. The adapter I am using is the default one that came with the laptop when I bought it, and it appears to be functioning normally as well. What could be the cause of this incident, and what can I do to fix it?

A:Battery Stated as "Plugged in, Not Charging"

Most likely you have a bad battery. Dell has had whole series of batteries that they shipped out in a not fully functional state. I have an HP laptop (about 8 years old now) that the battery took a "steamy one" and it will no longer charge properly. You can try this trick (it may not work, but worth a try because did work for me a couple times): power down laptop and take the battery out for 30 minutes; replace battery and plug in charger but do not power on; wait 4 hours of charge and power on. I had it work a couple times that it gave a full 100% charge. Again, if it doesn't work then sorry, but at least you tried.

As long as the temps are not too high there will not be any performance loss. I wouldn't worry about replacing thermal compound, unless you are experiencing temperature issues.

Hey guys, I'm pretty much a noob at this.
Long story short... My acer aspire 5552 will not stay on. When I turn it on I have to press on a certain area if not multiple areas. Before I had opened it and cleaned out the fan it use to overheat like crazy it used to hit about 90 degrees I'm wondering if that has ruined something?

Please help!
Thanks in advance

A:Acer Aspire 5552 won't stay on

First of all. Why do you have to hit certain area or for that matter. Multiple areas. It may still be running to hot. Or something was damage when you put in back togather. If it is running to hot . It may need new thermal pads.

Hi you all!

I have an Asus Laptop, last generation i7, 8gb... almost nice. Code: N550LF

Problem: I have to work all day with my laptop, with graphic software and so on.
Almost 10/12 hours or more per day. In my old Dell (I had it for 5 years) I changed for this reason the battery every year.
It is extremely important for my work, even if not everyone cares about battery.

Requested solution: what can I do to preserve (as much as possible) the battery?

What others said: A friend of mine told me to always plug in the computer, because the computer doesn't charge the battery when it is full. In this way I can preserve the battery.
The Asus website doesn't give any advice about it.
The official support by mail told me to not plug the battery when it is 100% charged. This could be dangerous. So, no way to preserve it.

And in your opinion?

Thank you in advance

A:Battery advice

Batteries these days like to stay between 20% and 90% charge.
Leaving the laptop/device plugged in when it reaches 100% does no damage, as most devices have an automatic charge cut-off. So you won't over-charge your batteries.
The problem is, that you're keeping the battery between 98-100% charge all the time, when this is not a sweet spot for the battery at all. It will degrade very slightly faster.
Therefore, in order to keep maximum battery life, keep battery between 20-90% charge.

Just ruled out malware in other section of this forum. Laptop's integrated keyboard suffers intermittent lock-ups for no apparent reason (sometimes works, sometimes doesn't, right now, doesn't). Touchpad seems deactivated (tried FN + F7 in case of accidental disable, but that's not the case), every option related to touchpad are grayed out in 'mouse' menu (config panel). Before malware check-up,tried system restore to last week, all problems were still there, so I reverted back. I have to use visual keyboard to type. Have to work with external mouse because touchpad doesn't work. Tried reinstalling touchpad drivers from Acer website, and didn't work. Computer worked perfect a few days ago.

I have a HP a1020n Pavilion I use to do audio reconditioning on, it's running WinXP. I've maxed the memory and have a terabyte drive installed already. My question is; should I bother to try to upgrade to Win7 and add a DirectX 9 video card and a better audio card to replace the onboard chip or just junk it and buy something newer with Win7 packaged with it? I've read one thread here by someone trying to install an upgraded video (Upgrading video card on HP Pavilion a1020n with ATI Radeon X1600 Pro PCI-e) and it doesn't paint a very good picture of trying to do any of this. Any thoughts/advice are appreciated.

A:To Replace or Upgrade?

It isn't worth the money to upgrade in exchange for the performance increase you would get.

What do you audio reconditioning with? What software? Potentially you could scrap XP, install Linux and use Audacity. Only costs you your time, no money.

I've done a fair bit of audio reconditioning of speeches recorded on cassette tapes with Audacity.

A:Minimize Battery Wear?

If your laptop allows you to, some laptops have an option to confine the battery to between 20% and 85% or something. That'll reduce wear if you can enable that. It'll also help if you manually do that as well.

Li-Ion/LiPo "wear" is well documented and the causes are well known for consumer chemistries.
Storing at high temperatures will increase degradation.
Storing at 4.2v/cell (fully charged) will increase degradation.
Keeping it below ~3.0v/cell (discharged) will degrade it.

So, in general, spend as little time as possible depleted or fully charged. If you fully charge it before leaving for the day, then start using it within a few hours, the wear is very minimal so you shouldn't worry about fully charging it if you're planning on using it soon, just don't store it for long periods fully charged.
Likewise if you leave it fully depleted for a long while, that will also accelerate wear.

If you need to store it, 40% charge (3.85v/cell) is commonly recommended but there is very little difference between storing it between 20% and 80% charge. Again the only times that storage can heavily degrade the battery is if it's fully charged (4.2v) or fully discharged (<3.3v resting)

I am having an issue with the sound on my laptop. It will play videos and music, but at some point the sound just....freezes. It is like when a CD has a scratch and it plays the same two words over and over again. Most of the time the screen is not frozen and I can click to exit out or shut the computer down. The sound, however, does not stop when I shut it down or unplug it. It only stops when I remove the battery. Any suggestions would be appreciated.

Hey everyone I have an old laptop with a battery that lasts about h in quot Power Saving quot mode I m going to be stuck next week for about hours at a location with few available public outlets and need to stretch my battery life as much as possible I ve already for battery to Looking life extend ways "techie" done the obvious generic tips of quot defragging the hard drive quot quot dimming the screen quot quot using few no external devices quot quot tweaking my power usage settings quot etc but it s not enough I m looking for some good quot techie quot solutions now like quot underclocking the CPU quot or quot removing the CD drive quot All suggestions are appreciated I d love to try to squeeze another hours out of this battery if possible no I don t have another battery and don t need to buy one just for this one event Thx PS Another idea Removing HDD and booting from USB Flash drive nbsp

A:Looking for "techie" ways to extend battery life

Removing the HDD and booting from a flash drive is probably the worst decision you can make. Flash drives have very slow speeds (even though they are flash memory, they arent fast) and very little capacity. Keep the HDD.

There are only a few more ways to improve battery life other than dimming your screen and adjusting the power usage settings. Under-clocking the CPU is really done by the "power saving" mode.

Try these suggestions:
1) Run this tool:
2) Turn of your network adapter. There is usually a switch on the side of the PC that toggles the network adapter on and off. That will save you a ton of power. Also make sure bluetooth is off. I dont think your older PC will have it, but just make sure.
3) Use this tool to remove any unnecessary processes from start up. This will speed up your computer while also reducing the amount of processes that run (thus reducing CPU and RAM usage).

I can suggest other options, I just need your OS. If it is Windows 7, it is easy too, if it is XP, I cant really help there since I forgot the OS.

Hi, I'm trying to install the XFX Radeon HD 5450 1GB graphics card into an Acer Aspire x1301-U1312. So far, I physically installed the card into the PCI express port (x16) but it doesn't seem like it's recognizing the monitor. When I remove the card and plug the HDMI cable back in the integrated GeForce 9200 graphics card, it works just fine.

What's the best solution to this problem!?

Any whom, thank you.

A:XFX AMD Radeon and Aspire x1301

Did you install the drivers before you physically installed the card? That would be my first suggestion. Check to make sure you put it in the PCI Express 2.0 x16 slot and not the PCI Express 2.0 x1 slot. Also, try the DVI or even the VGA connections on the card to see if those work instead. You might have a bad HDMI port on the card itself.

Hello all.
My sister in laws Acer aspire 5750z-4885 was recently sat on and the screen is cracked. I was going to replace it for her but before I order a new screen I was wondering if it is even just the screen and not something else that I cannot repair. The laptop since getting the screen cracked will shut off after powering up in about 4-7 seconds or so I haven't used a stop watch lol.
I am wondering if perhaps there is a short or some other dmg caused by the screen being cracked that will not be remedied by replacing it. I have limited experience with cracked lappy screens. Thank you all so much for any and all replies I love this board and it has helped me many times in the past.

A:Acer aspire 5750z-4885 shuts off after 4 to 7 seconds

Yes, the cracked LCD screen can be the cause of the shutdown. Replacing the LCD panel is not that difficult for someone experienced, but for you it might be too much. You have to disassemble the top cover without breaking the plastic. The video cable might not be included with the new panel, so you would have to use the old cable. The cable connection to the panel is very delicate...

I have a 11yr old Dell Inspiron 8100 Notebook computer. It started shutting down mysteriously while working, and sometimes shuts down a second or two after powering on.
I was planning to scrap the thing, maybe try to sell it for parts on Ebay, but decided to take one more look.
Today I found that the CMOS battery (reserve battery) is bad. It is leaking but has not damaged anything.
Could the fact that this battery is bad (maybe shorted) cause the computer to shut down as I described?
Since I have the whole thing dis-assembled I can replace the battery easily. I found them on Ebay but not sure I should buy one there, since it could be an old battery that is no good.
Any ideas?

Recently I was getting BIOS notification to change the battery as everytime the BIOS had to be reset.

I changed the battery 3 days back but again after a day I again started getting the same notification of changing the battery.

Pls tell where could be the problem.


A:CMOS battery problem

Was the battery you replaced the bad one with brand new? Also make sure it is a 3V battery and to be safe, make sure it has the markings 'CR2032" on it (that is what mine has). Other batteries of the same size and voltage MAY be fine, but I can't really vouch for them. Also, if you have one, it might pay to check the batteries voltage with a multimeter.

Also, if you buy a new one, it might pay to make sure that it is meant for a computers motherboard, as some may or may not be, just to be on the safe side. I don't really know a great deal about these batteries.

Hi guys

Hope you can help here. I'm building a box with an I7 CPU and an NH-D14 cooler. The cooler is so big it obscures the RAM stick slots, so I took it off, put the sticks in, put it back on. Given that the machine has never been switched on - it's never even made it as far as the case - and given the components are the same with the same orientation, is it really necessary to clean/remove and reapply the thermal paste?

Thanks in advance all

A:Do I need to replace thermal paste on a CPU that's never been on?

Opinions will vary, but as long as you haven't fully fitted the cooler and the thermal paste is okay then its fine to re-fit it.

It doesn't matter if the CPU has been powered, the issue is whether the thermal paste will still function correctly having been disturbed when you removed it. If you're in any doubt I'd remove, clean and add more paste.

Hopefully one of you guys can explain something for me. I have fitted a new battery to my Toshiba laptop and since fitting it the keyboard and mousepad refuse to work. If I plug in a USB mouse that works OK but still no keyboard. If I boot into safe mode everything runs OK.
I took out the battery and ran just on mains and everything runs fine and cpu is back to normal, putting the old battery in also enables the laptop to run OK.
Thinking the high cpu usage might be malware I ran Malwarebytes and Combofix but they found nothing.
Has anyone any suggestions as to why the new battery is giving these issues, never had any problems with other batteries I have fitted to laptops.

A:New laptop battery

There are LOTS of problems with new laptop batteries... one study reports anywhere from 6% to 11% of China batteries are unreliable or defective. you have no idea how long it has been sitting on the shelf or in a warehouse box in some shipping point.
First, clean you contact points with an eraser, and look for loose connection points, then consider returning to the seller for for an exchange.

I have a Dell Vostro 200. It has a hatachi 80 GB harddrive. It has no OS installed. I want to switch it with a 1TB hard Drive. 1st does it matter who the manufacter is? Dell wants WD. I want Seagate. And do I just load the XP Pro disc in and start? Oh, I don't believe it has ever been used. It was supposed to be a vista...yuck!

That would be the idea if you have it set to boot from disk in the system BIOS. The CD/DVD must have first priority over the HDD to boot.

A:Acer Aspire 7741g screen is not working

There is a device about the size of a five or six inch pencil at the back or bottom of your screen... called an inverter. It supplies the inverted image to the monitor. These have a tendency to burn out after a year or two in that model... they are not expensive... about seven dollars to a licensed tech, or perhaps $25 on eBay.

You have to remove all the screws around the monitor... then you unplug the defective one, and install a new one by plugging it in.

The hard part is removing all the screw covers carefully enough, then keeping track of all the screw sizes and where they go, then installing everything once the new Inverter is in.

The first one takes most folks two hours... after you have done a couple, perhaps 20 to 25 minutes. Of find a friendly tech who knows Acer and where to order the part..

I currently have a Lenovo laptop and have had it for 2 and a half years. The battery has always been pretty bad and last about 3 minutes unplugged. The hard drive is a temperamental one from an old laptop as the original broke for no apparent reason, probably didn't help I was constantly having to rebuild it too. I know it is stupid but when I got this laptop I was young and naive and didn't realise how essential recovery disks are.
I realise to replace all of these would be quite expensive so am wondering whether it is worth just buying a new laptop?

A:Worth replacing the hard drive, battery and buying recovery disks?

We need more information to comment.
There are at least 7 levels of Lenovo laptop... Is this a T-series... or just what is it? model and type.
In general, Lenovo laptops are among the most reliable...
This is not a good time to buy hard drives, due to the market over-adjusting to the hard drive factories under water in Thailand.
Batteries, good ones, can be found for $35 to $45
But you can get a 90 GB SATA hard drive for $90 or less.
Tell us the hard drive brand and size, the amount of memory installed.
All in all, we can rebuild a decent Lenovo for $140... and that is a lot less expensive than a new laptop. But a shop would have to charge you $205 or more.
A cheap laptop might cost you $500 to $600, but a good laptop could cost you $1200 to $1800. For long term reliability, I would want to invest at least $1000 to $1500

Tell us more so we can best advise you.

A:How to prolong your battery's life

Where did you get this information? Some of it I'd agree with, others I don't. It also reads like a post you copy pasted into lots of places around the internet - however a quick googling didn't return anything.

1.Store battery :
Put your batteries in a cool and dry place when you store it.
Yes, that is generally good practice for lots of things.

Do not charge your lithum batteries too full before storage.
Ok, no prob here either, although saying that doing so can decrease overall capacity of the battery would have made it a better statement.

After using the laptop battery ,please clean up the metal terminals with a soft dry clean cloth.
So, I should take the battery out of my laptop every time I've used the laptop while not plugged in. This is not practical on some laptops and ultrabooks, nor does it seem necessary since I have never seen a corroded laptop battery.

Before storage, you should confirm your is not fully depleted. If empty, charge for about 30 minutes . Usually a lithium-ion battery should be stored at about 40% state-of-charge.
I've seen 50% thrown around, but I'll accept 40%.

The suitable storage temperature for batteries is around 15C
Ok. Haven't heard this, but I suppose it makes sense.

Please notice this: weak batteries charge faster and remain on 'ready' indicator longer than strong ones. Also it only be used for a short time.So do not buy a used battery even if it is very cheap because used battery usually means weak battery.
This is confusing. Should define "weak". What does "remain on 'ready' indicator longer than strong ones" mean? Why would this happen? There are programs like BatteryCare for Windows and Coconut Battery for OS X that you could use to get information on a used battery before purchasing. Its possible with those tools to make an informed decision on whether or not the battery is worth the price. Simply dismissing the possibility of purchasing a used battery is lazy.

2.Charge battery :
Most battery can be fully charged in about 3 hours so do not leave a battery in a charger for a long time.
Are we still talking about laptop lithium batteries? They are intelligently charged based on circuitry in the battery pack to charge without overcharging, leaving in longer will not damage. A majority of battery chargers for NiCD, NiMH, and NiZn sold in the last 5+ years are also smart chargers and would stop charging once they sense a (typically) 0.01V decrease. Basically overcharging isn't a problem today.

When you prepare to charge your battery ,make sure the temperature is around the room temperature.
Makes sense.

Especially need to pay attention is avoid over-charging and over-discharging.
See above.

Do not charged to higher voltages than its threshold voltage ,as it would become unsafe.
As I said above, things are charged on smart chargers now, this isn't going to happen. It seems that starting with your #2 section you are mixing up laptop batteries and regular rechargable batteries like you use in a flashlight.

Prepare a new battery for replacement if your battery get weak over time.
Ok. Or you could just continue to use it, laptop batteries are expensive. If someone needed to get 5+ hours and now they can't, then of course they'll buy a replacement, don't think they need to be told to do so.

Please notice this: It is not very distinct to reduce the charge time by increasing the charge current .
What? Again, possibly talking about other types of batteries than lithium laptop batteries, but even at that I think you used a wrong word or two.

3.Maintain battery :
Rechargeable batteries do not break suddenly but slowly get powerless over time.
All? NiZn batteries have been known to "break" suddenly and not be able to be recharged. Lead Acid batteries in cars often start a car just fine, then the next attempt at... Read more

Got a new computer from an Acer Aspire 5250-BZ853 with 2GB RAM stock.
The website offered to add 4GB of RAM to the laptop for about 50 bucks so we went ahead and did that. However, when I got the laptop, it definitely doesn't run as fast as a laptop with 6GB Ram. I have run multiple tests and have confirmed that the RAM is installed properly, as system scans show that I have 5-6 GB of usable RAM available at any given time.

Running Windows 7 with the following system specs-
AMD Dual Core Processor E-350
AMD Radeon HD 6310 (graphics card?)
2 GB DDR3 Memory
320 GB HDD

Is the problem with the memory? Maybe I installed the wrong type? Not sure. Any help would be greatly appreciated.

Good afternoon.

I have a system that is a few years old and am looking to replace the motherboard, CPU and ram. the tower has a sata HDD and a PATA optical drive but the motherbaord has fried and im looking to upgrade to a more up to date setup.

Im not after anything extreme as I dont game and im only really interested in having a decent speed for internet use and word processing other than that im not overly bothered about being super fast.

I was thinking of an AMD CPU Phenom II 555 Black Edition Dual Core Processor but would like suggestions on a motherboard that would support such a processor and not cause me a lot of problems with the HDD being compatible

My thanks for any suggestions on this topic

A:Sugestions required to replace mobo and CPU

Here are a few reccomendations:
ASRock A770DE+ (Full ATX uses DDR2) = $54
ASRock M3A770DE (Same board but uses DDR3) = $60
ASRock 880GM-LE (Micro-ATX, DDR3) = $55
ASRock A785GM-LE (Micro-ATX, DDR2) = $59

These are all good boards and have SATA and PATA support it is just a matter of what form factor you want/need and whether you want DDR2 or DDR3 memory. With DDR2 you may be able to reuse your current memory but if you want to upgrade your memory DDR3 is a better option since it is faster and cheaper. If you have not heard of ASRock they are ASUS's budget brand and tend to have allot of Legacy ports (PATA, FDD, PS2, etc.) making them good options if you plan to reuse older hardware.

I am very very frustrated since I waited a while to get this motherboard from china. My last DFI board randomly died on me and I ordered this as a replacement because I wanted a decent 775 board. I worked on it all night tonight and despite it reading all the hardware... it will not boot unless I reset the cmos every time. On top of that... I can not get the bios to update... it doesn't read any of the 5 usb drives I tried (fat/fat32). Also I tend to get this grey screen when trying to flash it sometimes. I am beside myself at this point after fussing with it for hours on end and I really need some help.
