Laptop turning itself off

[Dark54555]

I've got a Protege 3505 tablet. All of a sudden, it's started turning itself off. Not freezing, it just goes from on to off. If you hit the power button, it boots back up. Thus far, it has happened when:
-Running a Norton Anti-Virus Scan in normal mode
-Running a norton anti-virus scan in safe mode
-defragging in normal mode (using norton speed disk or the windows defrag utility)

The drive is virus free (I removed it, put it in an external enclusure, and scanned the drive using my desktop). Disk doctor gives the drive a clean bill of health, even on the surface scan. All drivers are up to date, Windows is updates are current, Norton is up to date, and I've made no hardware changes to the system. Ideas?

I would ask the manufacturer, it could be heat, power, and/or possibly memory related.

toshiba.

it has no heat/power problems, as it will stay on for days so long as I don't run those programs.

it may stay on for days, but those programs are ones that require high processor/disk usage, and therefore generate more heat and require more power than normal usage. so it may be heat/power.

allow me to rephrase.

will stay on for days with 8 IEs, Outlook, AIM, and MSN Messenger, plus or minus a couple word documents and quicktime videos running.

none of those programs will tax the system (even running concurently), try running prime95 on it for 24 hours, or a DC project and see what it does.

Are you running those programs with battery power or using AC?

AC power.
