Thanks, I tried all the techniques including turning it upside down etc etc.
I didn't get maxwonga's message until later so it is at Rich Computer & Services, Wan Chai Computer Centre where the verdict is it needs a controller which requires a new keyboard. Total Cost $1,850hk.
I have my wife searching to see if it is still on warranty. If so, I will get it over to the Toshiba rep in KLN Bay.
Not unhappy with Rich Computer guys. They seem to be good as well as service oriented. I had spoke to them the day before and he had suggested going to Toshiba so I took it to them for a check as Chevalier's didn't pick up the phone Saturday.
I might just let Rich fix it and not bother with the hassle of taking it to KLN Monday rather than just be getting it back Monday fixed when the part arrives.
