SOURCE: MY IBM T43 fails to boot

Take out the hard drive and see if the laptop still shuts down. If it doesn't then your hard drive might be the issue. You can also try reseating your memory.

SOURCE: 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.

SOURCE: My laptop powers on but won't boot, fans start and nothing happens?

I just had same problem with 2 laptops. Power light came on and fan ran a few secs but nothing else. I replaced motherboard and CPU in one. The other just had to reseat CPU and it works like a charm. I thought it was AC adapter or LCD but it just had to be reseated. I would try that before I bought anything.

SOURCE: Hp pavilion dv9000 wont boot,coloured lines appear no bootscreen

This is caused by burn out of the Nvidia graphics chip on the motherboard. You need a new motherboard. This is due to a design flaw (the subject of a class action against HP in the USA). I have had two motherboards fail on me in this way so far - do not expect any worthwhile support from the HP "support" people they are all in India and can hardly communicate outside of their simple repetative scripts. Its impossible to escape them - I tried communicating with head office but all you get is contact details back to the incomprehensible Indian call centre. I strongly recommend against ever purchasing from HP again.

Dell E6400 won't boot up (most of the time)


Computer does not boot up
The problem maybe the RAM, it could be faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you.
Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.

Fisher and Paykel 7.5 washing machine keeps powering off during rinse and spin cycles


The pump has a thermal safety cut out on it.
If the pump gets too hot it cut out.
Just put a new pump in and your all going again.

My LG blu ray 3-D dvd player just stopped working. all it says is boot. I unpluged it but still just says boot. It was working fine. Now it wont turn on at all just says boot, its said boot for the pa


My LG 670 also said 'boot' after a upgrade attempt and appeared stuck there. I searched LG support for a factory reset option, which is: Disconnect the LG power cable from the wall / power stripHold down the power button the front of the player for 30 secondsRe-insert the power cordTurn the player back on. Note: my player showed 'boot' again for a few minutes, then shut off. When I turned it on again, it went through the normal power up cycle, then shut itself off (weird). I turned it on again. So far, so good.

Compaq f756NR laptop won't boot.


I think this is a problem with the laptop's LCD display. To verify this connect the laptop to an external display and see if it resolves the issue. If it does then its confirmed that its a display related issue. Since the issue has appeared suddenly I dont think its a serious problem. May be just loose/disconnected connectors. Should be a 10 minute job for a qualified technician.
If the external display too doesn't come on then its an issue with the graphics card and you may need to replace it.

Laptop wont switch on fully


Did you press F8 as you boot up to get boot up options and did try the Last Known good Configuration and Safe Mode?
If these didn't work I suggest you re-install Windows.

Sporadic Booting


Depending on whether the issue is powering on, or booting to the OS, will determine the failure in the system. If the system powers on but will not boot to the hard drive, then the answer may be the HDD is slow to spin up to operating speed. If this is the case, then multiple attempts to start the computer will spin up the drive but it will not stop spining before the next attempt. After several tries, the HDD gets to operating speed fast enough and boots.

If the system is not powering on at all, then I suspect a problem in the switch itself/motherboard.

Acer Extensa 5210 laptop wont boot


Try the following:
1) Remove power cord, battery and hold the power switch down for at least 30 seconds.
2) Remove and reinstall your memory module(s).

If those don't do it, get back to me for more ideas.
Thanks!
