Just a word of warning. The plastic fascia cover of the hard drive has two angle brackets that fit onto the hard drive caddy. I have never undone these brackets -they have a securing screw, but I assume no loctite -although I have taken out the drive a few times from the T41p, i.e when I changed the drive.
The T41p suddenly shut down a couple of days ago for no expected reason and would not restart. I took out the hard drive to check it externally and found that one of the screws had gone and I suspect, although not confirmed as I cannot find the screw, that it may have been related to the death of the motherboard. The screw can only have been there when I last put the drive back in place. (BTW, I am not sure about the actual screw size, M1.5 or similar, but an 8BA does the job!)
I now await a replacement motherboard before I investigate the existing board. (Fan works; LEDs come on; 1 3 3 1 short beeps when DIMMs removed; Lenovo replaced board a couple of years ago for GPU related failure, so could be just a fuse...)
