Colif :
i would take it back to the service centre as there might be more to it than just the HDD. They were ones who did the last work just 2 days ago, let them fix it.
Yes. I did send the Laptop back. But ironically it had started to work just fine. Like the problem never occurred at all! Still, I explained them the whole situation and they accepted it to test it for two more days at their place to see if the problem still persists. Today I got my laptop and it is working just fine. The service centre also told that they did not find anything wrong! Wow! I don't know what's going on.
Also, initially when the first time such error had occurred, like 2-3 weeks before. It got rectified itself. But then it started to show up frequently and one day it just refused to boot up. So, I think this time also going through the same series of events, it's just that I'm in the initial stage.
So what kind of (weird) problem is this? Or it's just my bad luck?
Thanks.
