HP 15-f162dx no video (DA0U83MBE0 REV:E)

[robante15]

Hello, I have an HP Laptop model 15-f162dx, when I connect the charger I have the charging light, also the battery charges correctly.

But when I turn on the laptop, it turns on the fan, but I have no video.

In the power source I could see the consumption, it does not have a short, it has a normal consumption as if it were trying to turn on.

I thought it could be a BIOS problem, so I reprogrammed the EEPROM with a BIOS for the same board serial number: DA0U83MB6E0

And now when you turn it on the fan turns on, but a second later it turns off, the source no longer shows normal consumptions, only a consumption that has a peak of 0.060A, and it turns off again, to start that process of turning on during one second and turn off again.

I have a backup of the original BIOS. But I would appreciate your suggestions on how I might proceed with this computer.

Thank you in advance for your comments.

Put back that Bios dump, try changing ram. Easy things first, only after that you should reprogram bios.

The RAMs were tested on another computer, and they work.
In addition, when turning on the Laptop without the RAM modules, the behavior was that the caps lock key blinked.

On the contrary, when putting the RAM in its place, it turned on without blinking anything

Make a request for bios in bios section and dont forget to post your original dump. There are many experts here who will spare time to build your bios. Hopefully that will fix the issue.
