When I start my laptop it boots up but after exactly 30 seconds it makes a "click" sound and shuts down.
Here are some tests I have performed:

1) changed my RAM memory -> nothing changed

2) checked my hard drive for errors -> nothing changed

3) started my laptop without hard drive -> still shuts down after 30 seconds

4) took out my CD-ROM -> nothing changed

5) my cooler is working fine, my laptop doesn't get overheated

6) the battery makes no difference if it's in the laptop or not

I've also made a log to see if it's always exactly 30 seconds. Here are the results:

NORMAL BOOT

1) 31.17s

2) 31.45s

3) 30.78s

4) 30.34s

5) 31.23s

F2 SETUP

1) 31.07s

2) 31.03s

F2 SETUP AND EXIT

1) 30.52s

2) 31.13s

F12

1) 31.28s

2) 30.97s

It doesn't mater how I start my laptop or what I do, after 30 seconds it just shuts down. Can someone please help me? I can't find any solution on the web.

  • Just for clarification, do F2 & F12 take you to the BIOS? – DaveP Feb 11 '15 at 17:02

    How can you say your computer isn't overheating. What you describe would fit perfectly with the CPU overheating. – Ramhound Feb 11 '15 at 17:14

    Agree with Ramhound. Without extra info - laptop old/new? Did you disassembled/replaced parts lately? - that's what's the issue. – AcePL Feb 11 '15 at 17:27

A few possible causes are shown in forums:

  1. Overheating: see http://en.kioskea.net/forum/affich-158211-toshiba-satellite-laptop-shuts-down-by-itself. If you can get to BIOS long enough to change CPU usage from Dynamic to Always Low, that might indicate (and partially resolve) issue. Have you cleaned the heat-sinks? Did you change clock timing that might cause overheating?

  2. Improperly seated RAM (see above reference), unlikely since you've replaced it.

  3. Bad CMOS battery: see http://www.tomsguide.com/forum/64361-35-laptop-turns-shuts-seconds-later-laptop

  4. Bad battery: see http://www.sevenforums.com/general-discussion/270289-toshiba-laptop-doesnt-start-up-2.html?s=c1b0db9809d35dced3d3a49c02109fb1. Though you've tested it working just from the mains, the power supply may need the additional filtering provided by a healthy battery.

  5. Defective part, such as a voltage regulator or filter or bypass capacitor... if that's the case, hopefully it's still in warranty, since professional repair is needed.

  • 'im going to test him about overheating, I'v changed my RAM, I have to replace my CMOS battery? my lapotop is already like 2-3 years old i think, no warranty – jeroen b Feb 12 '15 at 08:27
  • If I change my CPU usage to always low and try zo save and exit my BIOS he saves and exits but then he gets back to the BIOS and I can't move anything and still after 30 seconds he shuts down – jeroen b Feb 12 '15 at 08:57
