Toshiba satellite (1135-s155) turns on for 15 seconds then shuts off by itself.....
I am a comp tech, and have tried booting into Bios, with and without power plugged in, and it still always powers off after 15 seconds.
it was being used as a desktop and wasnt moved, so there isnt any signs of damage or abuse
powers on with or without the battery installed.

thanks for your help

have you opened the case and checked for dust bunnies?
is it a constant 15 seconds? or does the time that it stays on fluctuate?
does it jsut quit displaying...or does it really turn off (HD stops, no fan sounds..etc...)

it's possible that either the power cable is dead...or the plug on the back of the machine is no longer working....which would mean the battery is dead...and can't be charged...nor can the machine be run on wall power...hence the constant turn off

well, the power cable obviously cant be the prob, because it still turns on with out the battery.

second, it "really" turns off

and i have also tryed without the HD, memory, optical spindle, and memory

and yes constant 15 seconds

I am starting to suspect the power supply

could also be the power supply (but could still be the power cable...or it's connection to the laptop)..depending on how long this has been happening...there is a possibility that there is enough residual power left in the main battery to allow the thing to churn for a second or 15...(not 100% likely..but possible)...check your PSU and see if it looks like it's damaged

well, with the power cable plugged in the charge light comes on, and the battery is completely Removed

the PSU fan comes on, and no signs of abuse-- its a really clean machine, interesting seeing the customers house though lol
