Hi group, this laptop came in powering up but no display on either internal or HDMI. I cleaned ME of the bios (not sure if I did it properly, I followed SMDFlea's video guide but there was no file named "ME Region.bin but one named "ME Sub Partition.bin" so I used that name instead) and I get output on HDMI now.
The model name is 81Q4, board number NM-C531 Rev 2
Initially I got no +LCD_VDD voltage at the eDP connector but after testing U9 and U4406 I got 3.3V, no soldering or replacing components.
Now I get what I think is backlight (the logo lights up behind the...Today, 03:10 PM -
Hello!
This machine had the classic fault that all these motherboards have which is the loose pins on the RAM slot.
I soldered them as I have done on a few other of these and then it posted.
Everything works, fully installed with Windows 11 etc.
Only fault is when it has gone to sleep and you turn on again the screen is blank with no backlight and the caps lock does not work so I assume it has frozen completely.
Only way to get it to post again is to remove the battery! No amount of forcing off and on will get it to post!

I recently bought a used GPU that was advertised as an [B]MSI GeForce GTX 1080 Ti[/B]. The backplate label also identifies it as a GTX 1080 Ti, and the label looks untampered.
However, when I run [B]CPU-Z[/B], it detects the GPU as a [B]Radeon RX 480[/B].
I inspected the PCB and found a second label near the gold connector reading: [B]V341 VER:1.1[/B] From what I've found online, [B]V341[/B] PCBs are typically used for [B]Radeon RX 480[/B], while [B]GTX 1080 Ti[/B] cards usually use a [B]V360 PCB[/B].
Is it possible the card was BIOS-modded or relabeled? What's the most reliable...Today, 01:32 PM -

Hello everyone,
Ive got a [B]UE60KU6079[/B] on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously...Today, 03:31 PM -

I bought a case of them the battery cells are made in China the charge curve looks decent for 1 amp charging rate there is also a BMS protection board which here is the website link to them

Here are more of the same but the difference is that they do not have the BMS protection boards but have the tabbing on them

I have been pondering this question for a while but now I have see if this doable but I need to answer this question once and for all
I would like to know how to safely do this undertaking my first thought is to solder wires to the main filtering capacitors and see
what voltage I am getting and seeing if I can build a battery pack with voltage or not and if
I can find a BMS balancing protection board at this voltage level and weather or not do I have use more than one BMS balancing protection board...05-11-2025, 05:22 PM
