Bros, I'm a Computer Engineer, the keyboard is a replaceable part and can't be fixed with the above mentioned method. Simply replace your Laptop Keyboard.

computerboy:


I'm about to say the same thing. The truth about computer repairs is that it's not actually repairing but replacing.

udemzy101:

when I first saw the thread I was like hmmmm, but on a second thought this might work but 5% out of 100% .

computer repairs is not all about replacing,depends on what you're working on in the computer.

computerboy:


On the long run, replacing saves you money & stress than repairing. That's why it's highly recommended in CompTIA A+

This same thing happened to my keyboard some times ago, I noticed my laptop brings some unnecessary infos on startup and will refuse to boot, till I removed the keyboard and see the system is working fine.

I removed all the keys to the point that I can see the flexible panel, I tried cleaning with spirit, even kerosene and dried.

But it refused to work, instead the process worsen the case of the keyboard.

I just save myself the stress of repairing and get a new keyboard for just 3k.

Fixed it and viola my system resumes work without complaints.

A bad keyboard will make your system to malfunction, giving u unnecessary sound, cursor not working properly, windows not opening well or slow down etc.

what the OP might work but 99% of the time changing the keyboard is the best option.

Hello everyone, I will be discussing on laptop and desktop keyboard today. A while ago, a client of mine brought in his laptop with the complain that most of the keypads aren’t working.
Which usually are caused by some factors that I’ll be discussing in my next post (5 CRUTIAL TO DO FOR A HEALTHY AND LONG LASTING PC).
Immediately I collected it from him, I took it into my room and start testing the excess of the keyboard damage but it was just few of the keyboard that are working

HOW I FIX IT
I then decided to start working on it since am not yet an established computer repairer so basically I don’t possess the tools and equipment you expect me to have.

LAYMAN METHOD TO REPAIR IT?
You will need some certain things to get it done
ð A bottle of methylated spirit
ð Hard brush
ð A heater, in this case I used the sun since I didn’t have any

HOW I USED IT?
ð I firstly removed the keyboard from the laptop (you only need to lose a screw at the back of the laptop in most computers)
ð I applied the methylated spirit on the affected keypads
ð Then I used the hard brush to scrub the affected areas till the spirit dries off
ð You can do same for the back of the keyboard too
ð I then Placed the keyboard in the sun to dry up and heat up for up to (1hrs), depending on how sunny your area is

WHAT ELSE?
What else? Just fix the keyboard back and test if its working fine, if it doesn’t leave it for some minutes and keep pressing it till it heats up from the heat generated from the computer fan and start working smoothly.
if otherwise, repeat the procedure again by applying more methylated spirit and leaving it for more hours to dry up.
