Thanks for replying.
Connectors and connections looks good.and also if there was problem some keys are also working or touch pad must work.but both keyboard and touch pad are not working.
Does anybody faces that problem in this or other laptop? please share the experience .i will be great full to you.

Had this problem last year, built-in keyboard and touchpad would not work and could not re-install the drivers. BUT it would work with USB keyboard and touchpad. IIRC it was an Acer laptop....

Ran SFC /scannow and dug through the log - found possible corruption error for one obscure file (wdf01000.sys in this case). I got a copy from another machine, had to futz with the permissions to do the replacement, and that took care of it.

/* edit Built-in keyboard would work during boot, just not with windows */

You may be at the point where OS reinstall is necessary. Good Luck.

Thanks for sharing this,but situation is little different here,i tried to enter cmos setup but i couldn't able to because internal keyboard is not working and usb were working at the time of windows ,not at POST .so i when i cleared cmos i even can't able to boot the laptop because of "cmos check sum error Press F1 or F10 to continue" message on POST. All this show that problem is in hardware but final cause is little far from us.

Hi
Have you checked that the cmos battery is at aleast 3v?
if yes do you have 3v at winbond ic also clk signal
on those mb there are track breaks that you could easly un solder by mistake! you will need a schematic top go deep into this mb.

good luck
