Device fails to start after maintenance and reassembly.
Your friend's Dell Inspiron 15r 5537 is showing signs of overheating and performance issues. The steps taken so far—replacing thermal paste, adding an SSD, and using a Caddy for storage—help but may not fully resolve the problem. The laptop is still failing to turn on after the 7 beeps, which aligns with the Dell recommendation to replace or re-seat the motherboard. It’s likely the motherboard itself needs attention, so consider replacing it if possible or proceeding with professional repair.
Reopen it and see if you damaged the board or perhaps missed a cable.
