Both Shift buttons [keys] aren't working

[raidtube23]

I have a HP i5 64 bit laptop and both shift [strike]buttons[/strike] keys aren't working i tried turing off the sticky keys, reinstall the driver and repair the both [strike]buttons[/strike] keys nothing works.

i tried using another keyboard and its working. Please help. Thank you!

It might be possible that the keyboard has given out or that there may be something impeding the travel of the keypress through to the keyboard's PCB. Have you tried replacing the built-in keyboard? I'm curious though, how did you repair the buttons?

Model/SKU for your laptop?
