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

\015 My Sony VAIO VGN-FE770G PC Notebook is running only on AC power and is not recognizing the battery that it is currently plugged into. When I unplug my computer from the outlet, it completely shuts off rather than running on battery power or hibernating.\015

Answers :

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.

\015\012A 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.
It appears you Battery is defective.
\015\012Try to find a known good battery and see if it will charge and run the computer from battery power.
\015\012Laptop batteries go bad quite often and some go back a lot quicker than others. I have noticed that if a laptop battery is never allowed to run down all the way or at least to just below 10% power they do not seem to last very long. I have seen batteries go bad in less than year and some last as long as four years or longer.
\015\012It does not sound like your computer or charger is defective.

CTRL-Alt-Del sequence causes the laptop to attempt to re-boot but with no display. Putting a bootable cd in the drive shows a similar behaviou ie. nod display (screen reamins white). Any idea what causing the problem?

My sony vaio vgn-fs285e will not switch on since this morning. Even if the AC adapter is plugged-in it still won't come on. None of the lights come on, it won't run with the battery pack or just AC power. I just wanted to find out whether there is something wrong with the connection in my AC adapter or with the power port on my laptop. Plus whether there is anyway I can fix this or do I just get my hard drives removed to access the info on it and recycle the laptop. Thank you
