Re: HP G62 No Power Issue
I desoldered IO chip and soldered the chip back after cleaning the pads. After that I was able to see the AC power light near the DC jack and also The laptop powered on but no display.
I planed to flash old bios back but I took a rest that day. Today When I replug without doing anything I was unable to see the changing light. Not only that. I see the IO chip is heating up. Whats wrong? Bad IO chip I guess. I can't find same IO chip within My county. Can I use something similar???
Model No: KB3926QF D2
If I ordered the same chip. Do I need to program It??? Help pleaseComment

Re: HP G62 No Power Issue
This chip is not programmable. It uses a separate EEprom chip for bios program. KB3926QF D2 and KB3926QF CO are substitutes.Comment

Re: HP G62 No Power Issue
Here are the KBC list available here.
https://motherboard.lk/shop/?filter_brand=ene-kbc
Im thinking about "ENE KB3926QF A1" OR "KB926QF D2" Which are available to buy. Aren't they compatible???Comment

Re: HP G62 No Power Issue
harshen, does this G62 have an Intel or AMD GPU?
AMD versions of these computers have been known to fail due to the defective GPU, much like the 2011 Macs.
If it has the AMD GPU next to the processor, try reflowing it at a lower temp, being careful not to melt the CPU socket.Comment

Re: HP G62 No Power Issue
KB926QF D2 is same as KB3926QF D2. The suffix A1 is not compatible for sure.Comment

Re: HP G62 No Power Issue
I heard KB926QF D3 also same. So I used that chip but still nothing. even I can’t see 3v at power switch. Bios flashed still same.
whats wrong with this
Edit: I noticed that some always voltages are lower than mentioned.
10VALW——>7.22v
15VALW———> 10.24v
Is that okay???Last edited by harshana; 09-16-2022, 03:34 AM.Comment

Re: HP G62 No Power Issue
The HP G62 has a known fault where it won't turn on because of the AMD graphics chip. Did you notice if the CAPS-LOCK LED is flashing when you turn it on?Comment

Hi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!
A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about... -
Hello,
I have re-soldered the loose pins on the RAM slot which is a common fault on these models..
It charges and turns on the power LED but is missing several voltages like RAM and CPU do not come up which I believe is due to MAINON & SUSON being missing to turn these supplies on..
What I am un-sure of is what is the ITC chip waiting for to send out these signals, what are the requirements?
I have checked these lines in diode mode and they seam normal -> 600.
I have checked to see if they come on for even a fraction of a second... -
Back Story
I just recently purchased a RZ09-01652 Razer Blade 14 Touch v4(2016) as a project. I suspect the original motherboard had overheated and caused board damage to the vrm's for the CPU and GPU as now that motherboard works however will lockup on you often due to hardware clock issues.
So after some research and looking at options for replacement motherboards I got a replacement RZ09-01952 razer blade 14 motherboard which has the 1060 vs the 970m that was in my original motherboard. I have contacted the seller about the motherboard being bad however I doubt they will be... -
I am seeking guidance on an Acer Spin 1 SP111-33 that does not turn on when pressing the power button.
Below are the observations and troubleshooting steps I have taken so far: Observations and Tests:- Verified that all critical voltages are present:
- 3.3V and 5V are always present if DC is plugged.
- 1.8V on the BIOS chip is present.
- Checked the power button functionality:
- When pressed, the voltage drops to 0V, indicating the button is functional.
- Inspected the flex cable connecting the USB, audio, and power button to JUB1:
- Confirmed connectivity is intact, ruling out issues

hi guys, my motherboard will not start no matter what
when connected to ac power, the battery does get charge, led indicator glows red when discharged and turns white as it is fully charged.
but rest nothing happens no sign of life.
this laptop has one preexisting usbc power issue - so i use DCIN jack for charging my laptop.
with this issue my laptop was unable to power ON only sometimes i just had to wait some time.
but now nothing happens no matter how much i wait/ charge/ press and hold power button.
i have no knowledge of motherboards ....10-20-2024, 02:48 PM
