Any abnormality in the integrated components of a computer can prove harmful to its performance, but some general computer issues can be addressed without seeking professional IT help. Among the most common problems you may encounter are issues with the computer freezing and appearances of the infamous "no boot" or "blue screen of death." To repair a computer, you'll need to troubleshoot the issue and determine if the fix is something you can perform yourself; for more complicated problems, however, consider seeking the help of a professional.

Dell laptop keys are among the most frustrating keys to work
with. However, it is possible to repair many problems at home.
Most professional repairs involve replacing the entire
keyboard, so it's worth taking a few minutes to identify
possible alternatives. If your laptop is still under warranty,
contact Dell customer support for a possible free or reduced
price repair.

4. Repairing a Loose Key

Turn off your computer. Unplug it as well. Repairing a keyboard
is not dangerous, but it's always a good idea to take these
precautions before you repair a computer.
Computers may freeze on account of any hardware or software
issue, so here you need to understand the exact reason behind
it. Notice if the issue started when you connected any
hardware peripherals like a printer or scanner; then it might be
due to a driver conflict. If the issue occurred after installing a
new hard drive, then it might be due to insufficient power or too
much heat. Follow the troubleshooting pattern below to repair
your computer, if such problems occur.

5. Step3- Remove the key cap

6. Step 3 : Check the attachment
points on the key

The base of the key cap should have up to four attachment
points, where the key clips onto the keyboard below. Look
closely for signs of a broken attachment. Continue on to one of
the steps below depending on what you see.
If you're not sure, remove a functional key of the same size by
gently levering out each corner with a screwdriver. Compare
the attachment points on the two keys.

the key

8. Step4: Replace a broken key cap
If the attachment points are broken, you will need a new key.
Purchase one online, making sure it matches your laptop
model and the location of the attachment points. To put in the
new key, hook one attachment point onto the keyboard, then
rub your finger over the key until you hear two loud snaps, one
at each end of the key.
Alternatively, remove a key of the same size that you rarely
use. Place it in the former key's position.

10. Step-5
Fix the metal bar on large keys
The space bar and Shift keys are held flat by a metal bar. If this bar is⇧
not flat, you may need to re-attach it to the small plastic hooks on the
keyboard. The bar should run along the lower end of the key, with the
short arms of the bar running up the left and right sides and onto the
hooks. Once the bar is reattached, press the key cap over it and test it.
Once the bar is out of place, it often continues to have minor problems or
gets a tendency to slip out of place again. Consider buying a replacement
keyboard for your laptop, or having it repaired at a computer repair store.
If you are installing a replacement for one of these keys, the replacement
will come with its own bar. Remove the old bar first by gently levering it
upward with a flat screwdriver.[1]

12. Check for other problems
Loose keys are almost always caused by damage to the key
cap itself, or the metal bar of large keys. If you're certain the
key cap is in good condition, read the section on stuck keys
below. This covers damage due to spills, broken retaining
clips, or a damaged membrane.

14. Inspect your Device Drivers
Many times when doing a Windows Update, your system may
download and install an incorrect driver, which may result in the
computer freezing. You can check the status of drivers from
Device Manager. Any devices with a yellow exclamation next to
them are in an error state. Unplug any USB devices, if
connected, and see if the error goes away. If so, that device is
a problem. Power-on your computer and see if it works. If it
does, good; otherwise you can restore your computer to an
earlier configuration. System Restore will roll your system back
to an earlier set of drivers.

15. Inspect your Device

16. Inspect your Device Laptop
If your computer has power (you see lights, hear fans spinning), but nothing on the
screen, or if the computer starts to boot up and then crashes with a 'blue screen', there
are several possible issues. NOTE: Any hardware changes must be done while
computer is completely powered down and unplugged / battery removed!!
Try Safe Mode - if your computer will boot into Safe Mode, it is a software related issue.
Test Screen - If you hear the computer running, but see nothing on the screen, try
swapping monitors or plugging in an external monitor for laptops.
Test RAM - try carefully removing the ram and powering on. Most computers, when
functioning properly, will give a long, repeating 'memory error' beep. Power off and
replace the ram, one stick at a time, powering on when ram is properly seated.
Test Video Card - if your computer has a removable video card, try removing it and
either replacing it or plugging your monitor into the built-in video port if available.
If none of these things work, you are likely looking at a failed hard drive, corrupted
operating system or failed motherboard. It is best to seek professional services at this
time.
