Shuts down after 30 seconds

Laptop boots just fine then after 30 to 45 seconds later completely shuts down.

    Mine does the same thing. The battery light starts out blue then turns amber. Taking battery out just makes it shut down faster. ?? I read the part about CPU fan & I don't hear it running or feel air blowing out the side. But what do I do about that??



    Thanks in advance for your help & patience!

I've got the same problem. I've googled until my fingers bled. All the posts are from people who think they have an idea, or things to check.
The bottom line is I'm certain its going into thermal shut down, but I have no idea why. I had a meter on the pins of the fan plug and it gets power, and then shuts off after 2-3 seconds. Not a fan failure but the circuit shuts the power off. I had my finger on the copper slug on top of the chip and it never gets warm to the touch. I've changed thermal paste, I've changed ram, cpu, still no idea what is wrong with it. My DC jack is nice and tight, and the power supply I use is of the correct voltage, and amperage.

Remove the battery and connect the laptop to power outlet, if it works then it was battery. If it still turns off then it is probably the cpu fan. Check if it is spinning.
If none of the above the comuter may be set up to go standby after 1 minute.

  1. I've had my Toshiba Satellite A105 for as of April 08 two years my laptop battery will not charge- it starts green then turns amber color then shuts down, if I unplug the electric charger. What is the life of a battery? I brought it brand new in the box. Never used the battery-I usually have it plug in.
  2. Did I burn out the battery? Should I have unpluged it? Help

Acer Aspire One notebook.when turn on,starts to boot goes windows did not start screen,can choose option and windows starts to load then just shuts off.if you do not choose option shuts off after about 20...


This is generally a hardware issue - if the computer is under warranty get it fixed through Acer. If not you may need professional help. You don't mention how old the laptop is but if it is older than a year or two and you live in a dusty environment it could be overheating. If the fan is not running or always running on super-high then it is probably overheating.

Another thing to try is using a boot CD (any boot CD will work) and see if the computer still shuts down after that 30 seconds. If yes, definitely hardware. If not, possible that it's a windows issue.

Hope that helps!

My Toshiba P35-S611 shuts down without warning a short time (2 min-45 min) after it boots up. The battery isn't hot but the heat dissipation fins in the back are very hot.


Indications of laptop overheating problem:
  1. The keyboard and the bottom of your laptop are very hot when the laptop is working.
  2. The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
  3. The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
  4. The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).

Solution:
If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.
  1. Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes (for example Toshiba Satellite A70/A75) you have to open the laptop case all the way down.
  2. Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
  3. Clean the fan and the heatsink with compressed air.
  4. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.

Try a system restore - boot to safe mode and restore it to an earlier working state.

Laptop boots then shuts automatically off


Try this, if you have a fast hand, the second it boots, push Ctrl+Shift+Esc and end taskeng.exe.
If you can't do it fast enough, try booting into safe mode, going to scheduled tasks, and removing any suspicious ones.
If you don't know how to boot to safe mode, push f8 until you see a screen which allows you to choose safe mode.

Laptop boots then shuts automatically off


If you haven't tried it yet, pull the battery out and try booting from the adaptor only. If it boots normally, then your battery pack may be bad (shorted cell) or the regulator that has the job of charging and monitoring the battery pack while keeping your system running may not be healthy.
If you own any multimeter (at the cost of Chinese DMMs, everyone should own one), check the battery pack for charge. Under normal conditions, they should measure a couple of percent higher than their rating. You will have either Lithium Ion or Nickle metal hydride batteries in the pack so should measure some multiple of the nominal cell voltage of one of those types that are respectively 3.6 & 1.2 volts.
