I have a Tashiba lap top. The power will not stay on i thought maybe a virus so i did the scan and now can get it to stay on for 10 min, but then the power still went off. So then i took out the battery and did just straight outlet and got it to say on for 20 minutes, but then it still went off. I hear the fans come on and run, but the laptop is feeling more hot that normal. Still not sure what the problem is though. Any ideas i don't want to get a whole new computer.

— abrupt, total shutdowns that are accompanied by excess heat usually fall into two buckets: thermal protection kicking in, or a power-delivery fault somewhere between the adapter, DC jack, battery, and motherboard. 's idea to watch BIOS temps and try extra cooling is a good start; here are practical next steps to isolate the cause and avoid needless expense.

  • Check software logs first: open Event Viewer (Windows Logs -> System) and look for unexpected shutdowns (Kernel-Power events) or thermal/ACPI warnings. That helps tell if the OS saw a thermal or power fault.
  • Run a hardware monitor (HWiNFO / HWMonitor) and record temps and fan speeds for 15-30 minutes while idle and then under light load. Log files are useful evidence.
  • Inspect and clean airflow: use compressed air in short bursts, clear intake/exhaust vents, and confirm the fan actually spins freely. If comfortable, remove the bottom cover to check for dust build-up and fan bearing noise.
  • Test power hardware: check the AC adapter for frayed wiring, confirm its output with a meter or try a known-good adapter. Wiggle the DC jack gently to see if power is intermittent.
  • If overheating is confirmed, consider reapplying thermal paste and checking heatsink seating (advanced). If power-delivery is the issue, repairs often involve the DC jack or motherboard components.

Safety and cost notes: disconnect power and the internal battery before opening, use ESD precautions, and weigh a repair estimate against replacement, especially for older laptops. If under warranty, use official service.

Does it have temperature monitoring in the bios that you can turn on and watch it for 20 minutes see if it hit's the turnoff threashold? Also if it feels warm try putting a cooling pad under it and see if that helps. Does it just shut off or does one thing shut off and then everything else (aka does say the hard drive just stop or the screen with the rest following)?

i will check the temp and try the cooling pad. But everything goes out all at once. Nothing stays on. It's like the computer just shuts right off like it was never on.
