Can a mother board on a lap top be fried by the AC jack coming loose?

did you check it worked whilst in the shop and get them to sign the reciept to say that it worked.\nif no then you have no comeback.\nget you´re laptop back and start looking on e-bay for the same laptop for spares or repair(like broken screen but not motherboard faults)\nyou will be able to repair it you´re self by taking the base apart and putting it back together in reverse(a monkey can do this belive me just don´t have it pluged in or the battery inserted.\nhave fun and learn something interesting.

try CPU (processor) cooler there is an sensor under the cpu socket on the mainboard so when the cpu gets hot it turn`s off the pc and wont turn it back on until it gets cooled down,since you power it manualy

It could have been shaken loose out of the socket.  However, I doubt that with the amount of force that the CPU fan has on it, it will come off that easily.\n\nThe problem most likely is from a loose Video Card or Memory Module.  Open up the case, seat everything back in by pushing down on them and try again.

It doesn't sound good.  Sounds like something got fried. Possibly either the CPU or Memory.\n\nIf you don't see any lights on the motherboard, then it's possible the motherboard has fried.\n\nIf you hear beeping but no video, then that's probably the memory.\n\nIf you see lights on the motherboard but nothing else happens, then it's probably the CPU.\n\nNo matter what, it's not good. If you don't feel confident in swapping parts like the memory or cpu, then take it somewhere.

could be\n\nA. Power Surge!!\n\nB. Processor Over Kill\n\nC. Poor Wiring/Connectors\n\nD. Substandard Equipments\n\nE. Bad power Supply\n\ncould be any of this

The only way to replace a bad pcmcia slot on a laptop is to have the laptop shipped to the manufacturer where they will replace the entire motherboard. When something like a pci/pcmcia slot goes bad on a motherboard, the only way you can not void your warranty is to send it in and get it replaced by the manufacturer. This is no different than if the power port on your laptop broke off of the motherboard so that you could no longer charge the battery or plug it into a wall outlet.\n\nUnfortunately this will probably cost you some money (depending on your warranty, it could all be covered, but most likely you will have to pay shipping at the very least).

Bad idea because there is a higher probability that the board might create a short circuit and "fry" you processor, RAM, and other fragile hardware. It's always best to secure the board to the case chassis because it not only creates stability - it also ensures proper grounding.

PSU failure, where the volatge exceeds ~8.5v. Check the keyboard connector to make sure it's clean.\n\nHave an experienced person look at it (don't pay to have it serviced until a friend says so, that's just stupid)\n\nUsually the fuse connected between the power and the keyboard connector would blow out before the keyboard would.

You will cause a short in the IDE bus and frag the motherboard. Really bad idea.\n\nBuy an external caddy (USB2) and it will do the job. You can use the 'disconnect usb device' feature in Windows XP when you are finished dumping data.

I had a similar problem caused by an overworked power supply unit (PSU) which was cheap to replace, but in reality it's not going to be possible to diagnose over the internet as it could be any one of a number of hardware or software issues.\n\nMy advice would be to call some independent PC repairers. Some offer a no fix no fee service & should tell you up front what the cost is likely to be.

are you getting power or not. i would first check all the cables to see if anything are loose. i would also check the power supply. and also would look in you motherboard book to find how to reset the bios.

There should not be any problems. Your main board Bios should automatically detect the sound card and shut off the on-board sound chips.\n\nJust in case your system is not too "intelligent" you may want to go into the Bios settings and see if you need to turn off the on-board sound chip.

I used to have a Toshiba and it crashed and nobody can fix it. My suggestion: dump it and get a Gateway.

I would say you contact DELL, coz it could be a safety hazard issue here. They might even offer you a replacement in this case. Just try ur luck.

Somethings to do will be;\n\nOpen the computer and check all cables and connections\nRemove the CMOS battery to reset the Bios\nDisconnect any hardware that you don't need to boot up\nTake the Ram out and then put it back in\n\nIf none of this helps then it is either a power supply problem or the CPU is blown and the only way to find out which one is to remove it and test it with a working one.

It will kill you PC as soon as you turn it off. The processor will reroute its power connections and cause it to short out. There will be a small explosion when this happens and a brief fire. Be sure to have an extinguisher handy. Sorry about your PC dude. Hope you can buy a new one soon. See ya...
