Symptom pattern (sudden power loss, only restarts after cooling, happens on AC and battery) points toward a hardware-level protection or power delivery fault rather than a simple display problem. asked the right question about AC vs battery, and ’s note about cleaning is a useful first step — below are focused, practical checks that add to those suggestions and help narrow the cause.

  • Capture the event: on Windows open eventvwr and look for Kernel‑Power or thermal events (Event ID 41 and any critical thermal warnings) so you have evidence of an abrupt power loss rather than a software shutdown.
  • Isolate power source: remove the battery and run on AC only, then try battery only (if possible). Swap in a known‑good compatible adapter or measure the adapter output with a multimeter and compare to its rated voltage.
  • Memory and OS isolation: boot a Memtest86 USB to stress RAM and boot a Linux live USB (or safe mode) to rule out OS-level drivers causing shutdowns.
  • Thermal and fan checks: confirm the fan spins at POST/BIOS, watch temperatures with a hardware monitor (BIOS or HWiNFO/HWMonitor). If the unit only runs briefly and then cuts out until it cools, thermal protection or a failed fan/thermal interface is likely.
  • Visual inspection: with power removed, open the base (if comfortable) and check for loose DC jack, swollen/bulging capacitors, oil‑leaking capacitors, or a dusty blocked heatsink. Reseating RAM modules is quick and noninvasive.

If cleaning and basic swaps (adapter, battery) don’t fix it, the fault is often a failing power jack, motherboard regulator, or intermittent fan bearing/thermal paste failure. Back up important data before continuing diagnostics. If not experienced with laptop internals, describe the symptom pattern, which power sources were tested, and the Event Viewer entries to a technician — that will speed diagnosis.

sounds like its overheating ,solution ,get can of compressed air, blow out fan and heat sinc fins ,if that doesn't fix it ,take it to someone who fixes laptops !

Does this happen while it's plugged in or while it's running on battery?
