Lenovo ThinkBook 14 G2 ITL FLV34 LA-K051P bios

[SMDFlea]

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

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

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

• Troubleshooting Laptops, Tablets, and Mobile Devices

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.

[m1ch43lzm]

Maybe you accidentally moved a resistor near the 16MB BIOS chip when desoldering/soldering it, check with microscope
There's 2 BIOS chips by the way, one 8MB and the one you read 16MB, the full BIOS is split between the two chips, 8MB contains the ME region, 16MB contains the main BIOS code

Thank you for that m1ch43lzm but I was unable to test it... acter resoldering a bios (without any changes) it won't start now...
Is it possible that I "cooked" chip and now it doesn't work? when on the board and power on it is getting 3.2V but the power led is on for 2-3 secs then it is turning off and on again in the loop.
So annoying!
