Hi sancheti81. Unfortunately, your BIOS dump doesn't work for me. After flashing, the fan keep spinning for 2-3 seconds then stop. Is this BIOS problem or something else? If I'm using my BIOS dump, the fan keep spinning all the times.
Any idea?Last edited by Ikung; 06-25-2017, 09:26 PM.Comment

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..Last edited by Ikung; 06-27-2017, 09:16 PM.Comment

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?Comment

Hello
I have model AHL50/abl52 LAC710p - ac120ns. It doesn't turn on after connecting the battery. The battery is charging correctly. I remove the battery, restart the bios by pressing the start button for 30 seconds without a charger and it works. I connect the battery, press the start button and it does nothing.
When it is on and I connect the battery, I reset it and it works and detects the battery.
I have measured some voltages according to the schematic and they are correct.
Can the BIOS be corrupted?... -
Hello,
I have a motherboard from an HP laptop: AHL50/ABL52 LA-C701P. Idle consumption is 35 mA; when the power button is pressed, the consumption goes up to 85 mA and stays there for about 15 seconds, then returns to 35 mA at idle.
First observation: the UEFI chip is not powered (MX25L6473E). I've checked the schematic; the +3V_PCH seems to come from two MOSFETs, 2N7002 and AO3413L. However, I don't have either +3VALW or PCH_PWR-EN present. The PCH_PWR-EN comes from the EC (KB9022QD). I've tested the +3VALW_EC on a few pins and I have 3.3V on pins 22, 32, 47, 97, 98, etc.... -
Hearty greetings to everyone, trust you all are doing excellently well.
Please, I have the above problem, the laptop turned on after the switch was activated but it will turns off in less than 2 seconds.
The power stables in very rare case. Once it was stabled, everything works fine.
Once the power switched is pressed, 5V and 3V were present.
The things i have done:
1. I have check for shorts on the board, but nothing. The board is short free
2. Not a power switch problem, it behaves the same without the switch ...06-10-2024, 05:05 AM -
