Hello,
I am looking for a BIOS bin for an HP 15-EC2021nr laptop.
I got one from a reputable place I used previously, but after flashing the bios chip with their bin file, the DC jack light doesn't even illuminate, and they won't respond when I told them about it which is highly unusual.
Thanks in advance!

Re: hp 15-a0007nx LA-G07DP schematics
I have one of these motherboards that has the same problem with PU301. The chip doesn't seem to be shorted however I have no 3.3V output from it resulting in no 3.3V at the super IO chip or the power button. Has anyone had success replacing PU301 and getting the board working?
If I apply 3.3V directly to jumper PJ303, the board will come on so I know there isn't a bad capacitor or something dragging the 3.3V output down. -
Re: Busted Power Supply
Look for fried MOV's inside the power supply. Plugging 220 into 110 setting causes the 220 to double which will take out the MOV's and the fuse. You will keep blowing the fuse if you don't replace the MOV's.Leave a comment:
