My toshiba satellite lapto keeps turning itsel off every 20 min, what can i do?

With all due respect Juan, we're going to need a translator to English, or post in your native language, and perhaps an expert fluent in it can help you.

Hi miguel sport...
Go to the following webpage for your drivers for your Toshiba A25.

There may be a short in the battery, you need to try another to see if its a battery fault or laptop fault.

what you are to do is to put the Bootable disc into the cd drive and turn off the system later after turning it off re-ON the system and the program running setup will tell you to press any key to load from CD and you press anykey then it loads the operating system and reformatted the system and follow the instructions command and your system is back.
if there is anything try reposting ok

check the power cord to the laptop in the back wiggle it. check the lights. if they come on and go off with you giggling the power cord. the ac input socket may be broken. you may have to wedge it in one spot to get the two lights to come on let it sit there a while 20 min to charge battery some then turn on laptop.

Try the link below. Should have all the drivers for your Toshiba Satellite. Thanks

Sounds like a device driver conflick before you try to restore reboot the laptop and at startup press F8 at the menu click onsafe with networking so that if you need to download drivers yo can " Right click on my computer clik on manage look in event viewer and see when errors started to happen if the was a software update at the time of the error uninstall it and reboot the computer. if not you may have to restore the system to and earlyier date and loose data Good luck

Is it turning off by itself after being on for 20min... each time? I.e. is it consistently turning itself off after the same amount of run time? Check the bottom of the laptop... how hot is it? Might be an over-heating problem. Some freeware (MobileMeter) might help you monitor temperatures and see if it is a problem

Some excellent heat management information here:
