Re: HP DV4 no power, burnt component maybe get lucky
Hi, did you managed to fix that laptop? If no, could you please check if it powers up with the bios recovery routine? (no USB present just to prevent unwanted updates).
The routine is 1) unplug the power cord and battery 2) hold down WIN + B keys 3) plug in ac adapter 4) hit power button
If it powers up please commento so I can trace my issue that is no power at all unless I make this procedure but didnĀ“t seems to work to restore bios nor charging the battery.
Thanks and good luck
Hi Ktmmotocross, thanks for answering. Are you possitive on that? because I was almost discarding a power switch faillure since the system power up (aparently as it should) whenever I made the INSIDE bios recovery routine. No power at all in other cases, and no battery charge in both cases.
