some of the upper keys on the keyboard aren't working

Hi,

Try plugging in a USB keyboard and check that it works OK. This will allow you to use your laptop until the keyboard is replaced.

I say replaced because it is easier to replace the keyboard than try to fix it as you can cause more problems than you solve when trying to repair it.

Here is a link to the service manual for your laptop. Scroll to p.49 to see the pre-requisites and then the procedure for removing the keyboard. To install a new keyboard simply reverse the procedure used to remove.

Also on p.49 there are the part numbers for all the particular keyboards used by this model. Search online, using just the appropriate part number for your particular model only, in the search box and you will get suppliers for the keyboard.
