Can you just plug it back in? Probably broke the plugs when you disconnected it. Check with your computer shop if you can buy new cords. Make sure you bring your computer brand and model with you or better yet bring your computer at the parts store.

On the backside of the connector where the ribbon goes there is a small strip of plastic there.LIFT IT UP ON BOTH ENDS,SLIDE THE RIBBON DOWN INTO IT.WHILE THE RIBBON IS IN IT,PUSH THE STRIP OF PLASTIC BACK DOWN MAKING SURE THE RIBBON STAYS IN PLACE (ALL THE WAY DOWN) WHILE PUSHING IT DOWN.You may have to try it a few times to get it snug in the motherboard connection.Good luck!

probably itz either minor case of software corruption/improper ground/cpu fan..
or major case of faulty or defective main board/ram/addon/daughter cards..
..plz do check the following as in order:..
the Hardware part:..
1)a)
in power-on mode, open/unplug the data/vga cable of the monitor from
cabinet..see if raster or 'osd' is appearing on the monitor screen..if
so monitor is ok..else replace the monitor and see..[not applicable in
case of laptop]..
b) in case of laptop try to get output from
external display unit/monitor using vga port..if there's proper display
in there..the problem is probably with either the 'lcd' or 'ccfl' or
'inverter circuit'..
2) if u hv a graphics card, replace with a standby or onboard and see..[not applicable in case of laptop]..
3) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..
4)
see if the ram(s) is loose/faulty..open clean/remove carbon &
or oxide formed on the teeth with an eraser n resit it..or replace with
a standby n see..
5) a) see if ur hdd is noisy or emitting any 'ticking' noise (like 'tuk tuk' or 'kirr kirr')..
b) or if the system is not supporting either the newly installed device or itz software/driver /firmware
if so, u need either a fresh os installation or ur hdd is likely to b replaced..
6) remove/clean dust
neatly..dust is non-uniform in nature n may cause
jam/short circuitry/excess resistance n many more..resulting an increase
in heat..
7) open the CPU Heat-Sink with fan out of the
socket..put some "Heat Sink Compound" (available in local electronics
chip level spare market)between the cpu/processor and the CPU Heat Sink
*** fan..resit/fit it tightly in position..
8) on main/mother
board..see with a debug card for mb error..may b short..look for
defective capacitors(espabove1000mfd)/mosfets..go through the mb's
south bridge n the circuit lie around atx connector..the crystal clock
generator (if cpu isn't heating up)..
9) [in case of desktop] the
smps itself may b defective/faulty..check the outputs of smps viz. 0v
(black~ground); +12v(yellow); +5v (red, green~ps-on, violet~pg&
grey~sb); -12v (blue);-5v(white); +3.3v(orange)..the 'oscillator and
error amplifier ic',or pwm switching regulator circuit..look
for defective protector-transformer/resistance (esp 4.7k)/mosfet..
check the battery n adapter [main power], in case of laptops..
for
any further assistance u may plz leave comment and or testimonials at
any point of time, so that i/we can help or u think it to b helpful..
if u r not a professional, always better to seek advise from ur system admin/vendor....
Take a closer look at the key retainer, it's connected to the keyboard at four different points.
Assemble the disconnected retainer the same way as one on the keyboard and put it back in place.
Put the key cap on the retainer and snap the cap back in place.
