Few units of Lenovo Thinpad t490s had the same `backspace` and `enter` keys issues
Guys, I need your help. I have an issue with Lenovo T490s laptops – several dozen units in different configurations, and in about half of them, the same problem appeared over time.

Lenovo T440s fan issue
Lenovo Thinkpad T440s
fan needs to be replaced as it works way too loud
My old fan have 5 pin connector, I`ve searched and found out that all replacement fans on the market have also 5 pin connectors but only 4 of them are wired (one is empty- the blue one).
I`ve tried fan with 4 pins but it spins 100% all the time.
Anyone was after that issue? Any thoughts how to resolve that?
PS. sadly i no longer have sticker from the old fan to write here exact model numberLast edited by czacha414; 10-25-2023, 12:56 AM. -

I`ve found several threads on badcaps saying that it can be fixed by downgrading older version of bios. Does anyone have one?...Leave a comment:

I had problem with this laptop that in post it was giving TPM is missing warning. There was no TPM option in BIOS, I`ve tried all Windows/BIOS methods with no luck.

I`m using CH341 one, I`v started with the software that was provided with the programmer. It was reading my chip as:
