My toshiba a300 is going to sedenly reset & sometimes power off. mostly its hapning in higher screen resolution & during the to much busy of processor
First, Is the laptop fan, heatsink, vents clean free of dust. If it's overheating it will shut down to save components for overheating. The Graphic Adapter is a big heat producer. As to the processor running at 100%, It's also a big heat producer, shut down some of the running processes that are not needed. At startup their many programs that are not needed. Use this freeware program, it has many useful tools. Download CCLEANER at : http://www.filehippo.com/download_ccleaner/ This freeware program will remove the junk from your machine, in the TOOLS section, STARTUP section, disable ALL unnessary startup programs.

This sounds like a hard drive is, or has failed. Either that or the RAM (memory has gone bad)
Did you let the laptop overheat? Was it left on for a long time? Or is this just an old machine ?
I would replace the hard drive, and reload the operating system, that is if you really want to keep the laptop. If that solves it great! Also, did you notice if there are any "beep" noises, or error messages when it acts up? Often times, you can go on the internet and find out what the messages mean.

Okay firstly we need to establish whether this is a hardware or software problem. I would suggest to boot up from a recovery CD so that the OS is not in use for that time. If it boots well with the CD, then you should look for malwares and possibly repair the OS. However, if with the CD boot the problem still persists (no activity as you say) then you know it's not a malware or OS problem and therefore rules out software issues. So then we need to look at hardware. I suspect it could be a power surge - depending on whether you installed new hardware recently that could cause conflicts. I would disconnect the power cord and let it use up the battery power until it switches off on its own. The power supply should then refresh itself (no more power left in the machine). After that, plug it back into the wall to let the battery charge up again and see if there is any improvement. If it still won't work, then unfortunately it will need to be looked at for any other hardware failures. In that case you should contact Toshiba to help out. If any of my suggestions help you, please do rate me. Thanks and good luck. I hope it all goes well for you.

It's probably not a BIOS problem.
You should go to Control Panel --> Hardware and Sound --> Power Options --> Change plan settings --> change advanced plan settings.
Try configuring the setting for "Plugged in" and "On Battery" to be the same. That way your laptop won't go through wierd configurations when you unplug.
Try cleaning your computer with compressed air too.
