Did you check your power cord entering your notebooks power supply jack! sometimes the tiny male pin that is inside the notebooks power jack will come out or become loose. The solution to this is either replace the mother board, as most repair centers will recomend or two take the notebook apart to get to the motherboard and solder the pin back on. Note this is not for beginners and you will need someone who can do professional soldering with a strong silver solder. You need to take the power supply housing off and than you can solder the pin in place and replace the housing. The hardest part is breaking down the notebook and putting it back together. But if you lable your parts and screws and do it in a clean work surface with a rubber floor matt under you and maybe a anti-static braclet (as you don't want to short anything out) you should be able to do it.with knownedge of soldering small parts. this is the number one cause for most warranty work done on notebooks and laptops, cause we forget that the power supply is getting pulled on when we use them sitting on our bed or lap and moving around alot. That is why it is a good idea to always use a lapboard of some sort to set your notebook on, plus you want to have air flow under the notebook for the fans intake and exhaust, this will keep it running cooler and faster.
Tip, You should keep your Anti Virus Programs up to date anddefragment your notebook at least once every week or two along with disk cleanup and error checker, By clicking >Start>Programs>Accessories>System Tools>Disk Cleanup, and Disk Defragmenter. Or click "My Computer" Than right click "Drive c" than click "Properties".
A good program to install for free is ccleaner found at WWW.ccleaner.com, this software is free, with no adware, spyware, etc. it cleans your PC's temp. files and fixes any issues your system may have, Everyone i have seen use the program gets back anywere from 500 MB's to !.5 GB's of disk space back. it is well worth trying. Go to the site and check it out, it explains what you need to know to make an informed desision for your self.

Turn off Suddenly


Does the battery hold any charge? Also, please check the screw near the video port; is it lose? If it is lose, then please tighten it. For now, if you would move this laptop, please do not touch that area (the video port and its surrounding).

NF210 Will not turn or or indicate rechraging


Sounds like a capacitor may have burned out on the motherboard, and may be related to the power regulator for the battery. The power regulator on laptops is what regulates how/when/if the battery is charged. Either way, your last posting is correct in that the motherboard needs to be replaced to correct a potentially faulty part soldered into the motherboard.

My computer suddenly quit working. The power just went off


The most common reasons for that are

1. power adaptor or battery isn't working - power problem. Some laptops require the battery to be in the machine even when it's running of the adaptor. If it runs out of 'juice' it will just go off suddenly.

2. overheating - It can get full of dust and dander and overheat the cpu which will also cause the machine to go off suddenly. It shuts off to protect the cpu from burning up. Sometimes if they get hot enough it can still take out the cpu... If the cpu fan stops working it will also overheat.

3. Control Panel - Power settings - check to see if there's a timer set to turn it off after so long etc.

T43 LAPTOP NOT TURNING ON. EVENTHOUGH THE BATTERY IS OK.WHAT COULD BE THE REASON? KEYBOARD LOSE CONTACT OR ANY FAILURE OF COMPONENT


1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad
.
6. The motherboard could be defective & needs to be replaced.

My laptops 4520 is getting off suddenly.


What happens before is turns off? Do you receive any kind of errors? something happens?

It could be resulted by lose of power, let's say a dying battery, or maybe because the laptop is too warm.

Also, I would consider looking for viruses. There are viruses which can turn off the computer, but usually you see a count before turning off. Also could be hardware conflicting.

I would try the following- start the computer at safe mode, which can be done by pressing on F8 or F12 at restart. See what happens- if the computer turns off after a while, it's a power issue, and then you can try testing the battery and warmth of the laptop. If nothing happens and the computer looks fine, I would check if any recent installed hardware or software may have conflicted with something. Good luck and let me know

Sony Vaio PCG-6h4l laptop turns off for no reason. While using laptop on batteries it works fine and does not power off while using. But while using with electricity the laptop turns off for no reason,...


It could be that the laptop disables it's battery when you connect it with the power supply. When the power supply then fails it won't have enough time to switch back to battery. You'd best first try another power supply, and post back here if that doesn't help.
