Yesterday, it started acting weird. Started hanging, pressing different buttons by itself, and didn't do what buttons I was pressing.
Anyways, after that, i restarted the laptop, and same issue.
Then i thought i should open it up and clean any dust, which there was a lot of.
Then i assembled it, and restarted it... Then Caps and Num Lock started blinking! I opened it and did a reset, as suggested on HP's website as well.
Then, the mouse pad stopped working, laptop was working again. I opened it again, and checked if something's not plugged. And then, after assembling it, again, i see the same issue of Lights blinking 3 times in a sequence.
Now, i think either the CMOS battery is dead, or the RAM is. Because i only have one RAM of 8GB. And i tried removing the CMOS battery for 10-20 seconds, and the problem is still there.
After that, i now have tried starting the laptop without installing the only ram i have, and the issue is there, of course.
Thats why i think I should try replacing the battery as well as the RAM.
So, is that what you think too? Or is there something else you think the issue is...
