Fauzan, a tech wiz friend of mine was visiting us for tea with his family and I happened to mention my laptop problem. He had a look at it and told me that I could fix it myself. I couldn't really believe it until he actually showed me how.
In case you are wondering, my laptop is a Fujitsu Lifebook S7021.
A couple of days later I bought a brand new keyboard from eBay for only £30.
The one out of order is on top.
So it was DIY repair time.
First of all I had to remove the battery from the back and remove 4 screws holding the panels in the top front.
Without the keyboard, the laptop looks quite odd. Fauzan had already taken off the keyboard when he was in my house last time, so made it easier for me. I found out that if you break the keyboard connectors, you actually have to change the whole mother board, so don't do this unless you know how to.
The panel at the top came out quite easily after releasing the plastic latches.
Connect the keyboard to the keyboard connector carefully and then push down the connector locks. We had to lift them before we disconnected.
Putting back the panel at the top and then screwing it back in took less then 2 minutes.
At the same time, I also upgraded the RAM to 2 GB. Previously it was only 512MB. The laptop now works perfectly.
It was great fun and I probably saved around £100 as well.
