Hi, I have replaced a IT8176 in a Lenovo nm-d281 motherboard, and need to know how to program this keyboard controller.
The initial problem was an erratic behavior of numeric key pad, due to one of the IT8176 keyboard pins was shorted to gnd.
Now it completely doesn't work. I tried to R/W new chip with Vertyanov programmer but don't know which pin of the 34 pin keyboard connector have to be connected.
Does somebody know how it should be connected to Vertyanov or Svod programmer?...Yesterday, 01:31 PM -
zz0.8tpitu4y0i8zzI bought a ch341a (I'm waiting for it to arrive) and I noticed that the programmer has a bug that the data pins go to 5v when the VCC pin is at 3.3v (which is the voltage I'm looking for).
Instead of doing the 3.3v mod, I'm thinking of converting the 5v to 3.3v with an 8 channel TXS0108E through the ZIF socket but I don't know if that would work, because it has to circulate voltage and also information.
What I am looking for is something that will convert from 5v to 3.3v but without modifying the ch341a.
I can't buy the ch341a 1.6v that has...05-24-2024, 06:51 PM -
Hi there,
Recently I had a problem with my msi z170a m7 mobo usb c/3.1 port,
The port connects normally but when I transfer data it transfers with full speed (from the pc to the device I'm sending to) but it does not receive with the same speed, to make it simpler, if I plugged a wifi adapter to it, I can upload with full speed but I can't download with the same speed, but if I connected the adapter to different port it downloads at full speed.
I'm not sure if it's a HW problem or a SW one,
I have MSI z170a m7, with modded bios to install coffee...05-20-2024, 03:06 PM -
Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
Ive eventually managed to get it on and working but it's very temperamental...
The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...Today, 12:05 AM -

Hi everyone!
Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.
My issue: No backlight.
Model: QE82Q70RAT
Type No: QE82Q70RAT
The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.
So hopefully, I can fix this cheaper.

Hi all, I'm looking at what seems to be a nice puzzle
A ThinkPad T14s Gen 1 that stopped working more or less a month after the warranty expired. I tried to boot both Windows 10 and Debian 12 from a USB stick. In the first case, the system just reboots after showing the Windows logo for a few seconds, while I'm able to see the Linux kernel crashing if I boot the second in failsafe mode.
Interestingly, some times (unfortunately it's difficult to replicate) I manage to boot into Debian 12 live. Moreover, the kernel doesn't seem to crash always at the same point during...Yesterday, 03:43 PM -
Hello all,
I'm working on an Acer Nitro 5 (AN515-54) with motherboard EH5VF LA-501P with a short on the power rail.
I'm just learning board level diagnostic, but here is what I've found so far.
I injected 1.5v to one of the positive leads on the DC jack connector (PJP101) and read about 1.4a to ground.
I felt around for heat and found the MOSFET at PQB12 is rippin hot!
when i pulled the MOSFET from the board the short went away. In my mind it was a faulty MOSFET.
Ordered a replacement and got it installed only to find it gets very hot again and the short returns....05-23-2024, 06:07 PM -
