only keyboard replace on dell inspiron 17 5770

Yes, depending on how you define 'only'. The keyboard and palm rest are pretty much integral, you need to melt plastic tabs to replace 'only' the keyboard. I have replaced my 5770 keyboard. The repair manual is still (11/2024) available here: https://dl.dell.com/topicspdf/inspiron-1...

Essentially you disassemble the computer from the bottom. The manual explains the procedure step-by-step. For me, the hard part was popping the base cover, even starting at the corner as directed; it took more force that I expected. The second time I opened the case to upgrade the network card it went quickly.
