It might be possible for you to replace the 'upper case / palmrest' (top section of your laptop with the keyboard and trackpad.)

Check the manual to see, buy a generic computer repair kit with basic tools to open a laptop case, buy a set of screws in bulk from aliexpress. The screw sizes may not have to match exactly, but it depends on the screw and location.

You could try following the manual during the repair, but I found it to be cumbersome and unnecessary. I was able to replace the upper case of my laptop in less than 15 minutes by just looking at it and removing what was in the way.

Lenovo V series is cheap, prefer Thinkpads, especially T series. Used Thinkpads tend to still last a long time.

HP Pavilion and Dell Inspiron or whatever are also cheap and worse quality than the cheap Lenovos IMO. HP Elitebooks were fine last I touched them, years aho. Dell Latitude too, though bad models exist
