Can A Key That Has Broken Off Laptop Be Repaired?

Hello, yes , but it depends on whats broken , if a part underneath is broken off I think you'll need to get a replacement key , you can get one at a reasonable price at the place I got my W key from, they sell individual keys with all the fixings

They even have installation video guides which makes it easy to install. :)

Yes indeed minor damages like these can be easily fixed. Warranty might cover this damage depending on how it occurred. If it happened due to normal usage, they might. Otherwise having laptop insurance against accidental damages is always a good idea.

The key is very difficult to be repaired. The only possibility is that you could get another key of the same laptop then it can be changed.

Fixing key is not difficult. Just put the key on the right position and push it down. It will be fixed.

Yes you can get it repared you don't even need the key to type it just makes it easier to type but still the key is pretty important if you are in a hurry to type something out quickly.

Yes and it is very simple, you can do a search on ebay for the model number of your laptop and keyboard key, or go to individualkeys.com they sell single keys, thats where I bought my keys for my gateway mx6000.
