Laptop runs but no display please if somebody help me and fix these bin files
...

I'm working on a ThinkBook 16 gen6

223147-1
448.0TF06.0011

The board has 2 X usb c ports, both show 5v @ amps

I've checked the cc1 and cc2 pins and they have 0v.

The cc1 and cc2 lines go to this component marked

87 9B
M53

This is the over protection IC.

Can anyone help with a part number for this IC.

Thanks...

Hi team,

I bought a lenovo thinkbook 14-iil with a core i 5 processor, Radeon graphics chip, board number: DALVACMB8DO - REV D from an auction. It does not have a bios chip and my guess is that someone disoldered it, so I am planning to buy a new replacement bios chip but I do not know how to reprogram the chip, can someone assist please

Hello,

I need a BIOS file. The computer powers on, but there is no display. It seems to start up normally, but no video output appears.
The 1.8V, 3.3V, and 5V rails are normal. However, the CPU and GPU voltages are missing. After about 10 seconds, the 3.3V and 1.8V lines shut down, and the fan starts spinning at high speed.

I suspect a BIOS-related issue. I would appreciate your help.

I have a Think Book 14-iil without a screen, I think there is a problem with the BIOS.
Model: ThinkBook 14-IIL-20SL
Serial No.: LR0BSG2Z

Thank You...

Try BIOS extracted from Lenovo website, DMI inserted

MTM 20VE004HUS
​BIOS ver. F8CN59WW
DMI 20000-207FF
Win key 92000-9203F

If that doesn't work, check for hardware problem, in this forum quite a few with same issue (also on the ThinkBook 14 G2 ITL), some even died after reading BIOS chip from working laptop to remove password, probably cracked solder balls under CPU...

Would someone be kind enough to take a look at my BIOS? Computer has the usual problem of no display with caps + esc + num lock lights. I have enclosed both files. I extracted the one from lenovo, but could not proceed from there. Ended up with DOSFLV34_QS.bin....
