If you have a systemguard warranty on your laptop better contact Toshiba Techsupport (1800-457-7777) and they will gladly send your unit for depot repair which is free to replace the whoule keyboard. No charges including Shipment and handling.

If you are out of warranty, you can dismantle the laptop KB and spray a contact cleaner on that might fix the issue.

Hope this helps

Two things to check.
Open the laptop up and re-connect the keyboard connection. It has a locking mechanism so be sure to unlock that first. Also when you're doing that you can see if there's any water (tea) still in there to dry off.
If that doesn't work, then plug in an external keyboard mate, cause the only other way to fix this is to replace the keyboard, the parts to open up the laptop keyboard itself are intricate and it's much too compicated, plus I've never done that (Seeing as that it's all glued together).
Hope this helps, be sure to rate!
