Hi, I am running Windows 7 on a Toshiba Satellite L675D laptop

 

and a couple days ago certain keys just stopped working, I didn't spill on them or anything like that, my arrows were being kinda intermittent then they just didn't work, same with my z, Fn, and /? buttons (typed with on-screen keyboard) all other keys seem to work fine

 

I tried cleaning them with canned air and checked in the BIOS to be sure it wasn't a windows thing, I also tried a fully cold restart, removed battery and pushed power button for 60 seconds then put it back in and turned it on, but nothing has worked.

 

I'm really hoping I don't have to pull the keyboard out but I figured I would give an ask on here to see if anyone had a suggestion as I have seen quite a number of other people with a similar problem, many times with the exact same keys.  Any help is appreciated.

 

Thanks,

Eric

Hello Eric,

From my years of experience dealing with Desktops and Laptops, if random keys are not working,it can be a variety of problems, one being the most common, is the ribbon cable to loosen up inside of the computer, pulling the keyboard out and re-seating the ribbon cable is the most simple thing to try to diagnose the problem. The second problem is the keyboard is just faulty and is slowly failing, which you can replace it with a brand new keyboard for $20-$30 by finding a brand new one on eBay or Amazon by typing in the Part Number off the bottom of the keyboard on the white sticker. Third and most unlikely is the keyboard controller built into the motherboard is failing, which I very rarely see happens.

 

I hope this helps you out.
