Here is the way to solve Asus K61IC screen flickering

Ok, here is a solution for the problem that annoys you so far. I thought to write this post because I personally suffered from that. And I thought for a while I will never buy expensive laptops again.

So here are the symptoms I experienced during screen flicking period. This screen flickering happens 5 months after I bought the laptop. It is very random and sometimes screen flickers so that you 2-3 times a minute and sometimes few times for an hour. Screen becomes black/vertical lines as it flickers. And I noticed that it gets worse when it is on battery power.

I was able to figure out this as not related to software/driver issue. So it is basically a hardware problem that caused it.

This is how I solved it.

1. Unplug A/C power

2. Remove the battery

3. Remove back cover carefully (cases which cover hard drive and processor).

4. Now you can see processor (CPU), rams and graphic card (GPU).

5. Blow away all the dust in chips and then in cooling units of cpu and gpu using a blower. (never touch chips, soldering with your hand)

6. Adjust cables which have hinges and connectors just to verify them successfully connected.

7. Now replace the covers and you're done.
