Ok i have an unusual problem i have a hi grade laptop and it keeps going off and sometimes it will not come back on no matter how many times i press on off button .When it does this the wireless light stays stuck on. I have stripped it down to see if i can see if it is shorting out but i can not see a problem. Also when it does boot up sometimes you only have to touch laptop and it just goes off any ideas on this one?

I have a problem with my hi-grade 8615 laptop, i dont know much about laptops. when ever i turn it on the laptop sounds like its turning on and then it sounds like its shutting down. there are 2 lights that turn on and when the laptop sounds like its shutting down 1 of the lights turns off, the screen doesnt turn on whist this is happening. but sometimes it does turn on but if u move the laptop slightly it either crashes and you have 2 turn it off and on or it will restart itself, i havent a clue why it is doing this and if anyone could help me i would be very grateful, the people i have spoke to have said it could be a lose connection or something to do with the battary or power pack...would putting my laptop back to factory settings help at all?

First try taking out the battery, turn on your computer and the try wiggling the adapter near the DC jack. If it powers off doing this then you need your jack replaced. If you are sure this is not the problem and you are comfortable with it take the motherboard out and remove all extra pieces from it. Only attach what is necessary to be able to test it (power strip if there is one, lcd, keyboard, and mem if you have no onboard memory) then plug it in and turn it on. If wiggling the jack doesn't power it off try taping on the larger square chips(BGA's)See if you can get it to power off. DO NOT REMOVE THE CPU. If you have more than one stick of mem take one out and test them one at a time. If you have more than one slot test both slots. If you cannot get it to shut off add the extras one by one testing after you add each piece. Try the wireless card first. If you do this correctly you may be able to figure out what piece is causing the problem. Make sure you are careful not to touch the keyboard or anything else conductive to the motherboard while it is powered on. I don't know what level you are at in respects to knowledge of computer so I have to ask. Are you absolutely sure it is powering off? Sometimes if the lcd is going out it can appear to some as if it has turned off. If you have any questions please ask. This kind of troubleshooting can be a difficult task for most.
