I have already tried another original copy but i get the same results.
I even removed the new Toshiba 500GB HDD and installed the old WD 500GB HDD where Windows 7 was installed the same thing happened: the laptop shuts down after around 1 minute.
I think that is a motherboard problem Do you agree?
Possible but eliminate the RAM and HD first by testing each with extended CD scan. Try also with one stick of RAM, then rotate. Use slot closest to CPU.
I removed the RAM and HD and let the laptop boots. A black screen appears for around 1 minute also and then it shuts down automatically.
I tried to boot it with one RAM without the HD and then with HD but always the same result.
Before this happened my cousin was using it to watch a movie and he slept while he was watching and he forgot to charge the laptop and when he wake up the second day he saw that the laptop was off.
May be this info can help
Remove the battery and AC power, hold Start button down to release residual power.
Try running with only AC power.
Then shut down, insert battery and try with it.
Test the hardware.
Thank you sir for your help.
I made all what you can expect but no result. I will send it to a computer center to see where the problem is.
How can i test if the motherboard is not functioning properly?
