Hello,
Does anyone have a motherboard from the Lenovo T490 model FT490/FT492/FT590/FT531 NM-B901 and could take a picture of the CPU area, including all the components around it? I would be very grateful.
During the CPU replacement process, I messed up all the resistors and capacitors, and now I can't get it to work again. The motherboard was powering up before, but now it doesn't, even with the newly installed CPU. All voltages are okay, and I don't have any shorts, so I'm assuming I'm missing one of the resistors.
I've also followed the schematic and Broadview,... -
The board is:
FT490/ FT492/FT590/FT591 NM-B901
So when i press the power button, the keyboard , the power button, caps lock, numlock lights up for a second, fan spins , and it turns back off, that's it ...
Ok, so i opened it, i have 3.3V,5V,1.05V when charger or battery is connected, when i press power button, i get all the voltages on all the coils for a second, except VCCGFXCORE_I , if i read the schematics correctly there should be 1.2V,i don't know if this is or isn't important,because i don't know the sequence and is it a condition for... -
hello guys, can someone check the dump?
when power button is pressed, the keyboard and caps and power button went on for a second, and then died... then i tried flashing dumps i found, and now only gives 3 power light flashes when charger connected... i even restored original dump, and it only lights up power button 3 times....no keyboard light or caps or anything...
the chip is 25Q256JVEQ, 3.3V
the board is FT490/ FT492/FT590/FT591 NM-B901
the original dump is in the attachment... -

In a poorly executed attempt to re-program BIOS, I believe I knocked off SMD resistors near the BIOS chip (MACRONIX MX25L25673G) pins 1, 2 and 5. Since the resistors were low values, I attempted to make the repairs using solder blobs. I am inexperienced and the workmanship is admittedly poor. I programmed the BIOS chip with the initial firmware read I performed. In other words, I believe the BIOS firmware currently matches what it was prior to any work I performed.
Here are my current observations.- Board
