i just use youtube! no game harder, no heavy working..

this mother board is dead?

i try again and again search and find way for booting.

but everything not work.

please help me.. please..

 

If I understand correctly your laptop powers on and then off when the battery is connected, but does not power on at all when the battery is disconnected. If that is the case, this looks like the PSU issue. Try to get any Dell/Alienware/HP/Compaq PSU, plug it in and power the laptop on. If your laptop powers on and posts (might display an error about wrong wattage PSU), this means, you need a new PSU. Please let us all know if you resolved the issue.

 

thank you for your response. but i change the new mother board.. it problem is fixed!
dell said, ' it can't read adapter'

 

Glad to hear the problem is solved now.
