Question about Computers & Internet
Hello, this is a Packard-Bell igo 3453, a Nec Versa M300 clone. It runs well on AC power, it charges battery, and ''can'' run on battery, but :
- When running on battery, if CPU temperature reach 60°C the power LED shuts down, and few seconds later all the system shuts down.
- When running on AC with a charged battery inside, if I unplug the power jack, the power LED shuts down, and a few seconds later all the system shuts down. It's impossible to disconnect power while working.
- When powering up on battery, if the battery has been in charge before (even for one second), the power LED lights on for few seconds, then shuts down, and a few seconds later all the system shuts down.
- To run on battery after it has been charged (even one second), I need to remove and reinsert the battery, and it then run well until it reaches the fatal temperature.
This laptop had been dropped-down 5 years ago, it then had overheating problems and was sent to Packard-Bell for repair. Since this event (drop-down or repair, I don't know) it never worked on battery. I have two batteries and can say it's not relative to them. It's not OS relative as it happens also in BIOS setup.
I believe something is broken in power management hardware, but got no idea what it is. I recently repaired the loosy power jack, and feel like reopening it in few weeks. I would be glad to get help preparing this manipulation.
If you are planning to open the notebook make sure the cpu cooler is mounted flush and has the most possible amount of contact with the cpu for heat transfer. I don't know about yours but normally in bios you can set a fatal temperature shutdown. Try to look up what cpu you have (when you open the case) and see if maybe the temperature is set too low. Then you would be able to reset the temperature to something higher if possible and this would solve the overheating shutdown problem.
