Step 1: How to Repair Dell Laptop Keyboard Keys
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.
a Loose Key
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.
Step3- Remove the key cap
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.

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.
Step-5 Replace a broken key cap
Step-5 Fix the metal bar on large keys The space bar and â‡§ 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.
Step-6 Fix the metal bar on large keys
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.
Check for other problems
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.

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.
