My T540p FrankenPad (thelemmy.club)
submitted 1 month ago* (last edited 1 month ago) by FireWire400@lemmy.world to c/thinkpad@lemmy.ml

Some of you might remember the T540p I got for free from work a couple of years back - after its mainboard died I rebuilt my older personal T540p with the the remaining good components and a donor W541 I bought on eBay.

I'm quite pleased with the result. Its revised specs are: i7 4930MX, Quadro K2100M, 32GB DDR3L RAM, AUO B156HAN01.2, an HP Blu-Ray drive and an Intel AX210 WIFI card.

And a few stickers obviously.

how did you come to learn that a w541 would physically match your t540p?

The T___P thinkpads were just W series but GeForce instead of Quadro. And why make two computer when 1 good enough? Lenovo does this all the time.

It’s even funnier now because the T16 machines are literally T14 boards with an extension cable for the ports. And the P16s is just a T16 but Quadro.

When I did my switch I just looked up which mobos were shipped with the same case that my current thinkpad had. There are some websites that have whole datasheets about this kind of stuff

that's what i was hoping you'd share; which website(s) did you use?

The Thinkwiki or Thinkpad wiki are helpful for every aspect of the laptop

Reddit was also pretty helpful as well

It helps to look for compatible cpus for the model because they are sometimes dependent on a specific Motherboard but that is just somtimes helpful
