Hello. Does anyone has the board view cad file of this laptop? please share it. thanksToday, 12:25 PM

Hi,
i had a HP 640 G8 with a DA0X8AMB8E0 Board. I would Flash the BIOS, but i used a CH341A Programmer with 5V instead auf 3,3. Then I thought the BIOS was now defective. I have already replaced it with a new one (flashed the same BIOS).
With the new chip, the notebook has the same error. The charging port lights up once and then goes out again. The notebook does nothing more.
I iced the board with a cooling spray to possibly find a chip that gets hot or has a short circuit. Unfortunately, I didn't find any. I suspect a fuse might have blown. Does anyone...06-07-2024, 02:47 AM -
Hi guys,
I currently trying to figure out why the laptop of my friend did not charge.
It is a Acer AN515-42 (Ryzen 5 2500U), I manage to make it works on AC and battery but no charging.
At first it was not working on Battery, I discovered that PQ201 was knocked off and replace it => work on battery precharged on another computer.
I also checked the small resistors between PQ312 and PQ201 and even if they are ugly values are OK.
My issue, when I plug the charger computer off, it drains 0.25A during few seconds with amber light on (charging) then amber light blinks...Today, 11:52 AM -

Don't suppose anyone knows where I might find the lid switch/sensor. I'm building a custom PC using the board and want to be able to access the bios via hdmi external monitor. Schematics unavailable. The board in the back of the monitor is listed as a "sensor" board but I don't see how it would work in it's location. Might not even be able to access the bios this way and I might need to run a small screen just for Bios changes but figured it can't hurt to ask...Today, 04:40 AM

Hi fellow lifesavers.
I have a Samsung washer-dryer WD80N645OOW which died mid-cycle. No response to anything, completely dead.
Checked the socket, the plug fuse, all good. Took it out to examine the boards.
There is a relay clicking on the mainboard. Upon applying power, I can see a diode flashing on inverter board, after a while a diode on main board lits up for a split second, then I can hear a relay clicking. This repeats a few times, then everything dies completely.
I've been trying to examine the main board, but it's a bit difficult becuse...06-06-2024, 09:11 AM -

Hi,
I purchased one of those units for a project and the BIOS is password protected. I was able to dump the BIOS (Insyde), it's 8MB. Tried various ways to clear up the pwd to no avail. Hoping someone can figure out how to bypass it.
Thanks!Today, 07:50 AM -

Hello all,
I am repairing a Macbook A2337 and i have a problem
The Macbook is stuck in restore as someone before me tried a DFU restore and bricked the device, now i can't do a restore as AC2 throws error 1 which is related to the trackpad.
When i turn on the device i get the trackpad click for a few moments and then nothing, i tried 7 trackpads and 7 trackpad flats, i know all 7 are functioning okay, especially one as i use it for testing and DFU restore.
I inspected the whole board and everything seems fine.
Can anyone help me as i didn't fiddle with trackpad...Today, 04:26 AM -
