Hp dv5-1040 don´t power on

[davids2006]

Hi Guys,
I have this notebook, that don´t power on. The only signal that I see is the led near the power connector blikinng when I put the charger. No more led´s on or blinking only this. I change memorys, charger, battery and nothing.
Anyone knows if it´s a "ussulay problem"? Maybe the charger chip balance damage?

Thanks
David

Start with reflashing the Bios. As of your board i totally dead then you need a programmer, desoldering the chip and flashing suitable bios image off board. Your best choice is to flash the same bios verion that was on laptop before it gone bad. If nothing happens and u are sure of your bios veriosn is good then go forward with harware work.


ps always make a backup of your original bios even off board.

board is signalizing bad main power, so why reflashing bios?

Test it outside the case and see if something gets hot
