The computer when on power is automatically switching to battery

If on a GM car the battery has been disconnect the windows may need to be reprogrammed
The following steps explain how to program the side door window regulator motors:

1. Press and hold the power window switch until the window is fully DOWN. Continue holding the power window switch for approximately 3 seconds.


2. Press and hold the power window switch until the window is fully UP. Continue holding the power window switch for approximately 3 seconds.


3. The power window regulator motor is now programmed for the express function.


4. Repeat this process for all of the power windows.

You don't, you let it go into sleep mode.
AUTO SLEEP MODETo preserve battery, this computer will automatically switch to sleep mode and just displays the CLK data when it has not been used for about 15 minutes. The power will be turned on by pressing the SET button!

If your phone automatically shut off that means that the phone is not getting the power coming from the battery or the battery itself can no longer supply power for the phone. In this case, you need to try another compatible battery for your handset. If battery wont work with another handset, that means that your phone needs replacing battery.

Remove the Power cord and battery
Hold down the ON button for 30secs (dispersing all internal voltage)
Plug the power cord back in (leave the battery out for the moment)
Turn on

Does it work?
If so, shutdown normally
Re-insert the battery
Turn back on

check the wire in the power switch , maybe the power switch got stucked , remove the socket in the power switch , and go manualy switch on with the screw dricer

Hello.
First of all, try to charge it at least for an hour.
Then, check if it stills power off automatically with a full battery.
If it still does, you need to firmware upgrade it or just plug it to the computer and update it.

hope it helps.

Not really sure what your trying to say, but as far as i know, all laptop charge while they're plugged in and when you unplug it, it will automatically switch to battery power.

On the left side, towards the rear is a DC jack. Plug the power cord in there. It should automatically start operating on AC power, and charge the battery.

I believe the setting you want is in the bios. It has been a while since I have been in mine. It has to do with "restart after power failure"

And since your time/date are also off, I suspect you have a weak cmos battery on the board.
How old is the computer?

The battery looks like a watch battery. It is round and thin. It should be replaced.

- do a bios update (or downgrade if needed) to see if it fixes the issue

- but probably the BIOS battery is not keeping the proper voltage anymore, and it automatically resets the BIOS (do the bios setting that u change, remain changed after unpluging/pluging the comp ?!). Try keeping the computer pluged in for a day and see if the battery charged properrly (if the set date remains )... if not ..change the battery.

- as for the self starting, there is a setting in the BIOS, that activates/dissables that ! - see u;re user manual ...
