Re: Cmos battery

You must enter the laptop internally that is.  In some laptops it is soldered to the motherboard be prepared to find that.  Did you know it takes a long time for the battery to be stuffed because.  Are you certain that the problem is the battery?.  If it is stuffed your bios would have resetted itself to the default settings and will not hold your settings.

I forgot my sony vaio bios password

Remove the battery, remove the power cord and start taking the laptop apart. You will need to remove the CMOS battery located on the motherboard and let it sit for an hour or two. Then but it all back together. The CMOS battery is a silver battery about the size of a nickel.

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.

Sony vaio VGN FJ290P password reset sony vaio VGN FJ290P

I have set the password for administrator when i entered the bios set up. you can change its setting but not the configuration unless you've entered the password. you can't change the password with a new one if you cant enter the old password. Next time dont forget your password because laptops has its security even when stolen you cant open its bios set up if its protected by password. CMOS battery is in the mother board. You need a service technician to open your laptop to reset the bios setup battery.

The CMOS battery is located under the system board, and is not accessible from under the keyboard.

The keyboard has to be removed in order to change the CMOS batter, (another reason why I don't like Sony laptops.)

Below is the batter I just pulled from a user's VGN-FS660\W 892cbd5.jpg
