I have a 4 year old Dell XPS the monitor will shut down then the system after 10-15 minutes, then the entire system will shut down a few moments after. The power cord was replaced because I believed it was the issue since it 'fraid', however with the new power cord the same situation. Any thoughts? Thanks for you time...

Acknowledging the timeline from and the hardware suggestions from , below is a compact, laptop-focused troubleshooting flow that narrows the cause and points to likely repairs without repeating earlier guesses.

  • Reproduce in firmware: boot into the BIOS/UEFI (watch the manufacturer logo) and leave the machine idle. If the display or system dies while still in BIOS it is almost certainly hardware (power delivery, display cable/panel, GPU, or thermal shutdown).
  • External-display test: connect an external monitor. If the external stays on when the built-in display goes dark, suspect the panel, its cable/inverter, or LCD power circuitry. If both go dark together, the problem is upstream (GPU, power rail, thermal).
  • AC vs battery isolation: try running on AC only with the battery removed, and then on battery only. Different behavior isolates the AC adapter/DC jack/charging circuitry versus battery faults.
  • Thermal and fan check: observe fan speed and keyboard/hinge area for heat. Use a bootable tool or BIOS temp readout to confirm temps. Sudden shutdown with high temps points to cooling failure (clean fans, replace thermal paste/heatpipe).
  • Built‑in diagnostics and logs: run Dell pre-boot diagnostics (F12 on startup) and, if Windows is used, check Event Viewer for Kernel‑Power or thermal/shutdown entries to get an error code to guide repairs.
  • Memory and display cable: run a bootable memory tester (Memtest) for several passes; reseat RAM and display cable if comfortable opening the chassis.
  • Visual inspection: look for a loose DC jack, bulging battery, or damaged board caps. Avoid DIY BGA reflow; that is a last-resort shop-level repair.

If diagnostics point to the adapter/DC-in or battery, those are inexpensive replacements. If motherboard/GPU faults are indicated, weigh repair cost versus replacement for a 4‑year‑old XPS. Take static and warranty precautions before opening the case.

Hi
is it your monitor problem or cpu problem i dont understand
if the problem with cpu then pls chck following things
Ram
PSU
temperature of processor heat sink

I believe it's both, first the montor of the laptop shuts down then the computer, a couple minutes later... I have checked my 'power monitor' and again, the original powercord did fray, so I purchased a new one and the same situation with the monitor then computer/cpu/laptop. Thanks!

I think but i am not sure the problem is with your cpu
not with monitor you observe yourself performace of computor whether it is running too slow or getting hot accordingly pls check ram & power supply unit one of them might have faulty

Thanks for your input. I have replaced the power cord and still the same/similiar shut down. I have not replace the ram.

Insted of replacing power cord you have to replace power supply unit
