Problem with motherboard


If you are getting no power at all then the problem is either the Powercord is bad or the motherboard is bad. If you need to replace the motherboard, get a quote from one of your local shops, then try the guys at: http://www.generalsystemsconsulting.com

They will fix it and send it back by Fedex or UPS and the are cheaper the most and do a high quality repair job.

My e-machines laptop (XP) will not boot-up, black screen. I have tried starting in safe mode without success and via BIOS without success. As last resort I have tried using the restore cd and get as far...


You didn't say what happens when you try to start in safe mode or enter the BIOS. Because you say that you can't make a selection when you insert the restore disk, I suspect that either your mouse or keyboard have stopped working. Try a different mouse or keyboard. If that doesn't work, then suspect a bad motherboard.

My HP Pavillion dv 9000 that is 16 months old, past warranty will not give me any video. Geek squad says the motherboard is bad and not worth fixing.I spent $ 1500 on the lap top..anything I can do


Most likely the video chip on the motherboard has suffered from "cold" or broken solder points on the chip, therefore no video and or not booting correctly. There are repair facilities and exchange companies on ebay that offer repair or exchange at a decent cost. Your motherboard needs what is called "Reflowing" of the solder on the video chip. A new motherboard on Ebay can be purchased for around 200 bucks. I can give you a link to the service and repair manual that can help you with the disassembly and re-assembly of the laptop. There maybe a shop near you that may just charge a labor charge for the process. To give you a reference, I charge $75.00 for the tear-down and re-assembly, plus the part if I am ordering and plus shipping. That will give you some idea of what it will be.

Toshiba Satellite M35X-S149 Turn on PS, power light lights up, fan comes on and hard drive motor is spinning, than it completely stops working after 5 seconds. Power light stays on, no other activity. Also...


had the same problem, thought my motherboard was dead as I had this issue once before and the shop the replaced the first motherboard with a bad power connention replaced the motherboard
somewhere I read that a solution was to unplug the power and remove the battery, then hold the power on button down for 30 seconds
put the power back on and try to start
well the first attempt failed but I thought, try one more time, make sure it's at least 30 seconds and my toshiba came back to life -
worth a try

Motherboard or DC Jack Problem???


i agree with your logic and think its a good idea to get the jack soldered to the the motherboard before anything else is replaced and would hardly cost anything too

Dell Inspiron 1000 notebook won't turn on


The motherboard is bad. This model had a fault where after a while the North Bidge heatsink would break off and short the motherboard distroying it. This problem is something to not fix, it is not worth it, cost more than it is worth.

The problem is that the power inlet jack has a bad connection on the motherboard. The way to resolve this is to remove the motherboard from the laptop and resolder the jack. This is not a repair I would suggest for the novice. If this is not repaired soon, further damage can be done to the motherboard that may not be easily fixable. Please have this repaired soon.

Power fault samsung p28


Hello Robert C,

Man theirs a lot that can cause this issue,
First Remove the battery and try powering it with just the Power cable, if this works great you need a new/used battery.
Dose it make any "beeps"? Next try to Re-Seat the memory, and remove and Drives that you can. If none of these work it sounds like a bad motherboard.
