Lenovo ThinkBook 14 G2 ITL FLV34 LA-K051P bios

[majster-pl]

Check that, unfortunately it looks ok... I have picture form before and after - the both looks the same.
It looks like I've accidentally damaged something else on the board 😥
When I connect charger the IC is getting hot (checked with thermal camera) not sure if anything else can be done.

Make sure you haven't soldered the BIOS chip the wrong way, if it really got shorted, replace it with a new one (or one from a donor board with same specs) programmed with your BIOS backup
You can use a W25Q128JV as a replacement

Anything else we have to continue the discussion on the Troubleshooting laptops section

Thanks bro, but still the same. Maybe I should try a clean bios?

[Vibore]

Thanks, but that was toa nother user. but i tried it too, and stays the same. This mainboard as another memory, a winbond 25q80dvsig, close to charger port. Someone knows what it does, and have a backup?

Your laptop is ThinkBook 14 Gen2 ITL not ThinkBook 14s Yoga ITL, even if board number is the same the BIOS is different for the Yoga model
Post 132 is the correct BIOS for your laptop, hoaca388 extracted it from Lenovo website

You can try post 124 or 125, it's an earlier BIOS version, that will change your S/N if it works

The W25Q80DV is likely USB-C PD controller firmware, if laptop gets 20V on USB-C meter it's fine

Hi,
I have Thinkbook 14 G2 ITL. I have had a few issues with it and all was working for a while, until I upgraded the memory.
After upgrading, the screen no longer lights up or functions.
I have installed another bios from an earlier post and the laptop display now works however,

The battery charging is a little intermittant, I never had issues with the battery / charging until I changed out the bios.

Is someone able to repair my original bios please?
Both files attached.

Thank you

post the laptop serial number
read the forum rules..https://www.badcaps.net/forum/troubl...before-posting

[twonk9098]

Sorry, the laptop serial number is MP1YGF4K.

I note though that using a previous bios uploaded in this thread for someone else, I replaced the 128mb and 64mb bios's and the serial number within the Bios has not changed. Is this right?

Thank you

[m1ch43lzm]

Try, BIOS extracted from Lenovo website

ThinkBook 14 G2 ITL Laptop - Type 20VD
BIOS ver F8CN59WW
S/N MP1YGF4K
MTM 20VD000AUK
DMI 20000-207FF (on 16MB file)
Win key 92000-9203F (on 16MB file)

[twonk9098]

Thank you, which file (8 or 16mb) do I replace the DMI / Win information?
Many thanks

[m1ch43lzm]

8MB BIOS chip has ME region, the 16MB has the BIOS-UEFI region, I already added your DMI+Win key there
