Abhi hello and welcome mate some system specs would be helpful http://www.sevenforums.com/tutorials/180324-system-info-see-your-system-specs.html

Also look in Device Manager and open out Keyboards and see if there are any yellow triangles there.

Abhi are you still covered with warranty? because this is beginning to sound like it could be a physical problem with the keys themselves.

Just out of interest look in Control Pane; > Keyboard and se what settings you have.

 

[abhi24]

No warranty anymore become 1.5 year old, and I have PS/2 keyboard and driver version is 6.1.7601.17514

I dont this its hardware problem because its suddenly stop working few switches

 

[ICIT2LOL]

Hum that is what I mean Abhi it could be on a few of the more frequently used ones. By the by no spills dropped machine or other sort of physical damage?

Now a lot of laptop keyboard switches are the rubberized electromagnetic type that just short across the contacts and even though most are sealed that doesn't mean crud cannot or will not get in - see pic for rough example.

Sorry the pic didn't' turn out right the bottom block has two contacts that are shorted by the upper pad

I have cleaned my laptop same day probably while cleaning I have pressed many switches same time.do you have any suggestion for replacement, where can I find

 

[abhi24]

Or how can I repaire if possible then

Hi Abhi,
Is it always the samy keys? or do they change each time they stop working? and do they start working again after a restart or just when they feel like it?

 

[abhi24]

Few switches such as Y,1, U,9, C,-, and all switches in two rows

 

[ICIT2LOL]

Now you said you cleaned the laptop did you use any liquids on the keyboard when you cleaned it?

I ma still hunting round for a site that gives the disassembly of this model but even when I do find one the problem is going to be finding a replacement keyboard. A genuine one is probably going to be quite expensive and aftermarkets unless you know the store or site really well then you might end up with another dodgy board.

but on the brighter side it could be something simple like the small ribbon cable form the board to the machine that needs reseating or something but until I can find the site for taking it out I am stuck.

i cleaned with paper towel no water or liquid
