Subject: Persistent Power Issue with Dell Latitude Laptop

My Dell Latitude laptop shuts off automatically while in use. Initially, it would turn back on after cooling down, but after a few days, it stopped powering on altogether. I took it for repairs, had it serviced, and replaced the power supply, but the issue persists. Now, it's not turning on at all again, and I'm really frustrated with this ongoing problem and this laptop. What should I do?😞😔
