Hello nushy,

You can use a can of air to clean the keyboard or a slightly damp wash cloth or a cloth. Usually a can of air will work best but in case you don't have alternative.

Another option is change the keyboard searching in Google with satellite l350 Keyboard I found one at $22 + Shipping. I also noticed a lot of new and possibly malicious sites come up in the search. I'd stay with Amazon or eBay for safety.

If you go that route let me know I can give directions on changing the keyboard to help you.

Hello Rusy,

I am sorry that didn't work for you. It seems likely that some of the keys on the electric pad Under the keypads has short circuited some of the keyboard. Usually cleaning the keyboard would help but Its most thee circuit board. There is a way that you can replace a keyboard to solve this issue as stated by roger its kind of simple to do. I have found a keyboard on ebay that is 18.47 with free shipping http://www.ebay.com/itm/NEW-Keyboard-Toshiba-Satellite-L350-L355-A500-A505-/320622006208

I have brought parts from ebay in the pass and eBay buyer protection is like a warranty. I have replace keyboard with juice on them for free labor.

Do you have a bootable Windows disk? Any version will do. The goal is to test the the keyboard outside of the windows on the computer to eliminate the software as the source of the problem.

For example Windows 98 can be booted to a c: prompt and then you can type the letters to see if they all work there.
Windows XP you can choose the first repair option that will take you to a command prompt and you type into that as a test.
Vista or Windows 7 when you choose repair, have a command prompt available to test with.

The other question that comes to mind is, has there been any liquid spilled into the computer?

There is a utility in the Toshiba to create a System Recovery DVD set to use in case the hard drive dies or is totally infected. It is in one of the Toshiba sections of All Programs. I can't be more specific as I do not have my Toshiba L/T here. THis should be done on any new computer right after purchasing it. Just in case.

You could always create this. In fact you should have one of these in case of problems anyway.
Create a system repair disc

Once you boot it work your way through it to the command prompt, test all your keys.

Alternative is to press the F8 when the Toshiba logo appears and choose repair and see what happens that way once you get to the command prompt and test the keyboard.

My reason to prefer the first option is to not be loading anything from the hard drive when testing.

Good Luck
Roger

If the enter key isn't working when you use F8 to choose boot options, then you need to change the keyboard.

They are not that expensive. I can help with directions for that.

The other option is to plug a external desktop USB keyboard in and use that.

Try using a USB keyboard and see if the keys function correctly, if they do, it's probably the keyboard that needs replacing. I had a macbook with a similar problem and it was the logic board, not the keyboard which had been damaged from overheating, have you contacted the laptop manufacturer?
