My computer is about 1 years old. Its has an HP EliteBook 2540p and an Intel i5. My problem is that my computer suddenly and randomly switches off on its own. There is no blue screen, no error messages, the pc just goes off as though somebody pulled the plug. The motherboard power indicator LED remains ON. It might happen anytime from within 5-10 mins of starting up, to maybe an hour or two later. Sometimes it works perfectly fine and never turns off. And once it shuts itself off, i can't power it back on. If i pull the plug and try again later or shake up the chassis a but and retry, it might boot up again and run for some random period of time before the same story repeats. sometimes i remove the beettery and restart then it going to starts.
Please help me to my issue.

— several members here (, , , , , ) have offered useful hypotheses. The next step is not to guess a single cause but to collect repeatable evidence so you (or a tech) can narrow the fault quickly. The checklist below is a practical, low-risk workflow that complements the suggestions already posted.

  1. Reproduce and record: note exact timestamps, whether the laptop is on AC or battery, what apps were running, and any LEDs or indicator behavior.
  2. Grab Windows logs: open Event Viewer → System and look for unexpected power events (for example Kernel‑Power entries) around the shutdown time — save screenshots or export the log.
  3. OS isolation test: boot from a Linux live USB or Windows PE and run until the fault either appears or does not; if it happens outside Windows it points away from normal drivers/app software.
  4. Memory and disk checks: run a dedicated RAM tester (MemTest86 for several passes) and a SMART check on the drive (manufacturer tool or CrystalDiskInfo) and save the results.
  5. Power-path sanity: try a known-good AC adapter if available and, if comfortable, check the barrel connector for intermittent contact or voltage sag with a multimeter.
  6. Firmware/drivers: record BIOS/UEFI and chipset driver versions and, if newer vendor updates exist, apply them after backing up data.

Capture continuous hardware telemetry (use a monitoring tool that can log to file) and, if possible, set Windows to avoid automatic restart so any system events are preserved. Back up important files before prolonged testing. If the laptop is under warranty, avoid opening the chassis; instead gather the logs and test results above and share them with the vendor or technician — include timestamps, Event Viewer excerpts, MemTest/S.M.A.R.T. outputs, and whether the issue reproduces from a live USB.

When a lappie does that it is almost always a heat problem. If you must use it on your lap, keep your legs apart. On a desk - prop it at the back.
Still does it, then pop off the base cover around the fan and heatsink and remove the dust and fur. Nobody takes manufacturers to task over it, so they see no need to improve the venting.

Send it back to HP for repair. As gerbil mentioned, it could be an overheating problem, but the random time to failure makes me doubt that. I suspect you have a solder/connection problem on the motherboard or in the power supply.

Thanks for all your solution. hope to same issues again!

I found two cases, perhaps, it can help you:
1. heat issue: check the active-heatsink/fan and try to change it with better one.
2. It's motherboard issue.

Can that happen if the cmos battery is dead

This is due to overheating causing the processor under the cooling system fan to switch off. I came across this problem once and when I replaced the processor it work perfectly. (That for laptops only).
If a desktop PC then check the capacitors around the processor, One or two must be leaking. Just have it replaced with correct specs & there you go.Good as normal.

it could be the cpu then again i used artic silver on my PS3's CPU cooled it down very good and made my ps3 a whole lot better
then again it might be the capacitors but whats really worse is the psu overloading or your motherboard is about to get fried no offense

I had this on a laptop years ago, and the battery connector was loose.
