In reply to Matthias U. When you say short the connector in order reset cmos, could you provide more details, unfortunately my daughter powered off my laptop during bios update, now wont turn on and no lights showing although adaptor is working fine. Your details and break down is the best I have found so far, although for me i found after i had already stripped the laptop down.

I would like to correct you the Realtec sound chip is located on the hard drive board, The one on I/O is Realtec card reader chip.

Very useful guide. I needed to upgrade the wifi-card as well as run a 2nd antenna lead behind the screen & used the instructions/images above. I did notice that some of the screws in the guide were not present in my specific laptop & a few others were present that weren’t included in the above images. I do not believe it was due to a newer fab run, but instead installation variations on the factory floor. There is a place for a 2nd antenna on the left side of the screen, but was probably left out under the notion of “savings” when its more a “right to repair” & upgrade deterrence.

Thanks for the deets, mate. Thought I’d have to do a complete disassembly to clear the CMOS and reset the BIOS, so I did. Couldn’t find the CLRTC jumper or a CMOS battery, then the solution was in the comments.

For what it’s worth, Google brought me here, and this page more than any other helped to resolve my issue. Saved my PC from being a worthless brick. Much love.

In reply to Tom. I need to trace power sequence from EC chip. F555uj ver 2.0. Only got 3.3 5v and 1.05 volt. Other coils show zero. And no 0 ohm shorts. Schematic? I'm suspecting. ec chip

In reply to benglist. There's no CMOS battery. Why would a laptop have one? If the main battery ever is low enough to no longer power the RTC, keeping the CMOS settings is the least of your worries. Remove the main battery, leave it for a few minutes, short the connector, leave for another few minutes, reassemble.
