The easiest way is to check if the retaining lugs on the keyboard have been bent or damaged, may need easing back into place gently.
Then clip the white spring into the lugs and slip back into the recesses.
Then align the key into place and gently press on the key and it should snap onto the top retaining plastic lugs
The number 2 key has
Do you mean the " symbol?
by "upper case" do you mean when you press the shift Key?

These keys share a scan line in the keyboard. There is a break in the scan line or a bad connection between the keyboard panel and the controller circuit board inside the keyboard (or the motherboard in a laptop computer). Most keyboards use a pair of flexible plastic sheets with the scan lines printed in silver ink. These are attached to the controller with a "flexible printed circuit" connector. Sometimes the material tarnishes where it makes its connections there and the keyboard fails as you have described.
Most of these connectors have a friction lock that is disengaged by sliding it about 1 mm along the length of the flat ribbon cable going into the connector (there is a stop at this point - do not force the lock past it). The lock looks like a frame around the top of the connector box and has a slot for the cable. Once the lock is disengaged, the cable will slide out. Now you can clean the contacts on the cable (both sides) by polishing them with a white pencil eraser. When that is done, seat the cable back in the connector and push the lock back in until it makes a soft click or bottoms out on the connector shell. Once in a while there will be a connector that is friction fit - there will be no lock, but the cable will have a stiff reinforcing sheet attached to it. Very rarely, the lock will be a flip-up tab on the side of the connector - these are usually used only on smaller, narrower ribbons.
Avoid touching the circuitry on the controller board - it is easily damaged by static electricity.
If this doesn't work, you'll probably have to replace the keyboard.
Random keys will stick every
Usually caused by some liquid or dirt getting under the keys, you can try blowing a can of compressed air under them to try and clean them, or if you have the patience of a saint, can remove and clean each key in turn with ethyl alcohol (not advised), failing that, a replacement keyboard is the only solution
How can i install wireless mouse on my laptop?
Your mouse will have a "reciever" that plugs into an open USB port. If it came with installation software, install it first. If it's a logitech, then it's "plug and play". But I believe the logitech mouse comes with an advisory statement to go to their website and download the software for that particular model.
A few ke will no
the best and most appropriate approach is to test another keyboard, it will save you a lot of time. If the other keyboard works, then replace the old one. Hope this helps. Any question please feel free to ask.Good luck.
