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?...

by Stigsolbjerghi again
this time its a mainboard from a mowerrobot, when i connect battery it shorts it, so the bms shuts down battery.
when take the mm in beepmode and measure from the positive to the negative battery terminal on the board it beeps shortly like 0,25 sec, and when i reverse the probes it beeps again shortly 0,25 sec.
when i mesure on the cap thats missing in pic nr 2, the bottom solderpath goes to the negative, the upper one is 1,2 ohm to negative is this a short?

by karloxHello! Greetings, can someone help me check the BIOS backup programming of this laptop? I backed it up with NeoProgrammer, but when I transferred the code to the chip, the device's power LED turns on and then immediately turns off. The tragic thing is that it was working; I made a backup because I replaced a chip that was causing the battery not to be detected. I tested the device and it worked, the battery was detected. However, as a method I sometimes apply when working with devices with power issues, I erased the BIOS IC and reprogrammed it, but this time it failed. I downloaded the BIOS from...

Kinda as the title says, some dufus managed to drop a password in said bios & I'm running around in circles to clear it. FWIW, I've included the 8MB - 64MB & Asus' support site bios-zzzz. Seeing as I'm not a code guy in the slightest, I could sure use the help.
I thank all you MENSA Society members upfront for your help in my silliness.

by SageHappyHello guys,
I hope you are all good. One day my Lenovo thinkpad 11e laptop just started displaying "Thermal sensing error" after I switched it on. At first I thought it was an issue to do with a defective thermal sensor in my fan. I replaced the old fan with another used fan but, the problem still persists. From where I bought the fan, they said the fan was working just fine so, my question is how can I rectify this problem. Thank you in advance.Today, 12:35 PM -

I am repairing the A2780 (M2Pro 16").
There is no schematics and board view of A2708 yet, so I am referring 820-02100 (A2485).
Stuck 5.2V, 0.02A
'PP3V8_AON' short on diode mode and no voltage.
'PP3V8_AON_MPMU' short on diode mode.
'PPBUS_AON' looks fine. 12.3V
'PPVIN_P3V8AON' looks fine(not short on diode mode), 12.3V
I tried to remove the U5700, Q5800, Q5820, Q5840 and PP3V8 aond still stuck.
It seems to be a problem in the process of moving from 'PPBUS_AON' to 'PP3V8_AON'.

by zdwenaGood day,
I have a motherboard from a Lenovo legion 5 laptop. The previous service was unable to repair it. So I started the repair myself. The motherboard wouldn't turn on at all. The problem was in the mosfet in the PU101 which starts the power supply and in the PQ8203. And in the burnt Lenovo IT8227E chip and also in a short circuit in the power supply. I fixed and replaced everything. I have the same parts board. Now the board turns on and the battery is charging, the power button lights up green. But I am not getting the image. And the board turns itself off in approx. 25-30...Today, 04:49 AM -

by Dan the DogI need to find a replacement for this diode on one of the six gate drivers of a full-bridge IGBT inverter for a servo motor. It has S3 on the package. How can I find out for sure the right diode that I need. I believe it is schottky because it has 0.2V drop across.
The anode is on pin Ve and cathode on pin DESAT on 316J gate driver IC. Also would be nice if anyone had an idea of the purpose it is serving as it is not included in the suggested schematic of the 316J datasheet.

by mv270Hi
That laptop wont charge I dont know if the charger is genuine.
To investigate further does anyone know about
how the id pin works for this model, is it a pullup to plus or a analog voltage divider or a
complete digital exchange.
