It is not uncommon for someone to trip on the battery charger lead and break the socket where the battery charger lead attaches. If there is a thin pin in the socket, is it very wobbly.

Take a look at the socket where the lead from the battery charger goes. Either the battery is failing or the supply of electricity to the battery is failing.

If this does not work, it might be that the battery has no charge. Remove the battery and reattach with a bit of a hard shove in case there is an electrical contact problem. If you have a laptop, check that the battery is connected properly. If you do this you will ensure that you get a new one that will have the connectors you want and the right strength in output Watts. If you are a novice, just disconnect all power supply cables, unscrew the unit and take it to a computer supplier. Replacing a power supply is easy and not that expensive. If you computer is completely dead when you turn on, that is no fans, no lights, nothing, the your power supply may have failed. Power Supply Failure Power supply unit is broken (desktop computers) The cables to be mainly concerned about are the ones that connect the hard drive to the motherboard and the cables from the power supply unit that connect to the motherboard. It is always worth a try to recheck cables by removing and re-attaching each in turn. Particularly if your have been moving a computer around, or you have opened the case for any reason, it is perfectly possible that a cable is loose or there is not a good electrical connection. Unless you have experience, or you can find a step by step guide to disassembling the laptop base, don't do it yourself. Laptops are really unfriendly in this matter. Furthermore, if you have a laptop and it has a separate video card, then you can only get to the video card if you take the laptop base apart. Of course, your computer may not have a separate video card. This is much the same problem as with the memory modules, except the video card need to be reseated. The bad electrical contact occurs as a result of a gap opening up, or a bit of corrosion or dust getting between the electrical contacts. Sometimes you have to repeat the process a few times. Try taking out the memory modules and the putting them back (with a bit of a shove). Take the power cord out the back of your computer and open the case. The computer will be lifeless when you turn it on except perhaps for the case and CPU fans. You will not hear the usual beep, nor will any text appear on the screen when you try to boot. If just one of the many pins on the module fail to connect in the motherboard slot, the computer will not start. It is a very common cause of boot failure that a memory module is not properly connecting with the motherboard.

Most of the time the issue can be solved in just a few minutes. The constant heating and cooling of the computer, atmospheric conditions and dust can all play a part. This is a very common causes of computer failure in older computers. In many cases, problems can be fixed and your computer up and running again in a short amount of time. The most common issues are explained on this page. The causes of computer failure to boot up can be broken down into four categories as follows:Įach of these categories holds a number of issues that computer fixers see on a very regular basis.
