EBay, Amazon or other online retailers. Search for the keyboard with model of pc. (I.E. HP dv7-1245x keyboard replacement). There should be no shortage of parts anywhere you look.
Hi Linda
You must be old enough to remember the old way of setting up screens. That was when they were CRT's (Cathode Ray Tube).
The large picture tube used to use Deflection Coils on the neck of the picture tube (magnetic coils) therefore requiring adjustments to the alignment of the screen (by adjusting magnetic signal from coils) Hard to Explain any further.....
Cathode ray tube
So.... Modern devices that use LCD or LED or Plasma Displays.
These are all modern Digital devices that do not have any adjustments to be made. Basically it is all coming directly from the Video Memory to the pixels in the screen.
All computer controlled......Ones & Zeroe's 1 - 0
So..... where is the problem?
Probably a loose or broken cable between the video memory and the display. Usually carried over a thin flexible flat copper connector which goes between the gap between the computer and the moveable screen.
When you open your laptop screen & close it... it can eventually crack this cable & therefore some screen dots (pixels) are missing.
To determine location of break. Carefully watch the monitor LCD screen as you open and close to see if it glitches or fixes the problem. Probably someone will have to replace this or some other cable inside.

Depending on your laptop model, you may need to hold a function or "Fn" key to get them to work. If you need further help, I’m available over the phone at https://www.6ya.com/expert/aaron_eefc4ebb3e929c59
try moving the arrow over towards the edge slowly and see if it changes from a pointer to a double ended arrow
if it does the right click and hold down and move the column border right or left to get a change of column size.
do that for all borders
