Re: can anyone tell me what chip controls hdmi and volume on this main
More than likely would be the chip under the heat sink. You could try looking at where the traces go see if they go to the HDMI ports. I do notice that there is another chip to the left of it that is not covered by a heat sink, and it seems like the traces that go to the HDMI inputs go through that chip as well. However the HDMI input on the right just above your VGA input seems to have its traces go directly to the chip with the heat sink. So if that input also doesn't work then you know your main IC is the issue.
hope that helped.Comment

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8... -

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
I have a short on the main power chip. Is swapping a chip of a donor board possible? Is there anything else I should check first?
Thanks
