Question about Sony VAIO VGN-FS640W Notebook

1 Answer

Sony Vaio Model VGN-FS640/W does not show having a battery.

Sony Vaio Model VGN-FS640/W works while on the charger but turns off once unplugged. It was working with no signs of battery wear at all. I installed a Linux OS (JoliOS) and once I unplugged the laptop it shut down and would only restart until I plugged it back in. I reinstalled windows, and tried a bios update, but it didn't help. Are there any suggestions? Any help would be appreciated. Thanks,

The main battery needs to be replaced, or the charging ciruit on the motherboard is not working, remove main battery get a stiff toothbrush and clean terminals in the laptop incuding the battery, if no change! check the device manager to see if battery is present, if no! reset bios to factory default.

SOURCE: Sony VAIO VGN-FE770G only runs on AC power, battery not working

This looks like the system is not able to sustain itself on the battery power. I have a doubt here. Is it a new or an old laptop. Either Case we have to suspect the battery charging and battery condition. One another reason could be that the battery contact is not good. But this could be of the least chance as the manufacturing of such devices would be perfect in all standards. Lets check the battery power first.

A sony Vaio never operates if the battery is not detected or the battery is not charging, while the system is up and running, you can see a small picture of the battery in the system tray which is at the right bottom corner of the screen. Run your mouse over the same and you will find a tooltiptext message and you can see if the battery is charging or not. If not, your hardware has a problem. If its charging but the battery charge is not increasing, then you have a battery problem. If its a battery problem and that the system is under warranty, you can well get a replacement for free. Hope this resolves the issue. Good Luck.

The battery might be damage for the time of use or maybe you put in a inadecuate space, the computer works perfectly without the battery but if it doesnt occure and the computer dont works with out the battery and the charger dont supply the energy of the pc maybe you can try with a new battery and a new charger if it doesnt solve the problem your internal hardware is damage or your software is corrupted or damage too.

Battery shows full charge, but when unplugged drains within minutes sonny vaio vgn-n220e


Battery most likely has dead cells, the live cell that is still working is showing 100% but does not enough juice to keep the computer running by itself. You need a new battery.
