Hi Before anything did you try and force display to external monitor? Unplug internal display cable see if you have display on monitor.

Hi
Never released schematic..... I wanted to see if secondary voltage was present if keyboard is lighting up and external mouse either one... If it's not then see if you are getting RSMRST 3.3V & S5 3.3V on the kbc you could pull the data sheet for that to fine them pins if not bios is not working ...also could check with just adapter plugged in don't press the power button probe the board with just adapter plugged in them big square coils check all of them see if one has 3V and one has 5V this is always on voltage it's needed before anything and it must be there if not you need to check that buck controller that controls them output also the high and low mosfet on that line also. they would be either under the KBC or right nexted to it .

Hi Techman1025. I did replaced the CMOS battery with a new one. No display on the screen. Do you have the schematic diagram for this model? Thanks again for helping me.

Hi Techman1025. Did you mean by using USB mouse and USB keyboard? No lights on USB mouse & USB keyboard. Fan keeps spinning all the times (with my BIOS dump). If I'm using your BIOS dump, fan spins for 2-3 seconds then it stopped. I've got 2.7V on CMOS battery. Screen broken? Or BIOS ME problems?

W '

Well first you need to put a new Cmos Battery in anything lower then 3V is no good for sure.

Ok first check to see if you have Rsmrst3.3V & s5 3.3 also dcjack led on? see if keyboard or mouse lights up at all... If yes ..i would start with core voltage and crystal 32K see if it's present.

I checked again this motherboard and it was only one chip. The BIOS dump didn't work for this model. When I press the power button, the fan keeps spinning for 2-3 seconds then it stopped. There is no short circuit and no overheating on this motherboard. All voltages are present. What else should I check?

Re: Need BIOS Dump For Laptop HP 15-ac126TU, AHL50/ABL52 LA-C701P Rev:1.0

Thanks Techman1025. One question, this motherboard didn't has the EC chip. Err..how do I flash it?

You sure? If there is only one chip then just flash it with the 8mb file . That's all is needed just double check

Hi ala_borbe. Thanks for the BIOS dump but it didn't work for my laptop. Fan keep spinning for 2-3 seconds then stopped. Maybe this is not a BIOS problem after all. Thanks again for your time ala_borbe..
