IBM and Lenovo ThinkPad laptop enthusiasts!
I'm not sure about having a non-oem drive installed but they may wipe it.
In 2022 I bought a P15 gen2, after the first week I plugged in the charger and something blew on the motherboard, I sent it out for service and got it back after about 3 weeks. They mention that any drives may be wiped, when they repaired mine the OS was reinstalled despite being seemingly unrelated to the charger issue. They also replaced my i5 mainboard with an i7 so I have no complaints.
I'm not too worried about them wiping it, as it's a completely different drive with a fresh install. 3 weeks isn't too terrible for turnaround time, college starts towards the end of the month so hopefully I can get it back before then. I've heard of them upgrading parts during warranty before but I've also heard of them using lower parts, it's already an i7 model so fingers crossed it stays that way
Just got it back from the warranty center! Instead of replacing just the TrackPoint module, they replaced the whole top cover & TrackPad (I did mention that it was having similar issues to them). Came with the factory plastic on it. They didn't try to short-change me in any way, didn't try to argue that it was normal or that it was wear and tear or anything like that. It works better they day it was new, and all of the scuffs that I had on the corners are now gone (so is my intel sticker but I can live with that).
All in all, 10/10, still strongly support Lenovo's laptops.
