my niece has an old Thinkpad and it is so easy to switch HDD’s its crazy.
See there, even GeronL blames me!!!
Of my 3 laptops, this one is the most work to remove/replace the drive. Have to remove a dress panel first then the mounting screws for the cage, then remove the drive from the cage... Still not all that hard though.
I have an old Thinkpad (Pentium 233) that I thought I could run some diagnostic software on, but couldn't, um, borrow the software (even though it was a DOS program.. long story). Also got it on EBay, and the previous owner had installed WinXP on it which was very taxing of its resources. It does make a decent DVD player though for road trips since it came with a DC power cord...
