My old laptop XPS 15 is shutting down again and again. The HDD is 80% full and the battery has died, so I am running it directly via charger. What could be the problem? Will getting a new battery solve the issue?
Probably a heating issue.. get it serviced (cleaning and removal of dust)… And also get the fan speed checked..
PS: Get it serviced only at a reputed shop, coz doing it right is critical for life of Laptop.
