I have used this laptop for a lot of time now and I started to face many problems after just a few years of usage.
The battery drains out very quickly when not connected to a charger. I also replaced the battery but faced the same issue.
The laptop overheats a lot and becomes very uncomfortable to used by keeping on the lap which basically destroys the whole purpose of the laptop. Also, many times it crashes due to overheating.
The CPU usage stays in the 90% -100% range even when the laptop is idle, without any open applications.
