Car: 1995 Nissan 240SX Rep Power: 45 ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | Dog got at my laptop power cable - could it damage my laptop? I am very ticked off at myself right now. I wasn't watching closely enough and my puppy got at my laptop's power supply cable Of course, it had to be the bit that's not easily replaceable and right at the base of it, too, where I can't repair it.If I bend it around, it causes sparks (which I assume is because it's closing a circuit that shouldn't be closed). As long as I have it sitting still on my desk, it doesn't do any of this. I'm obviously going to have to crap out some money that I don't have to buy a new power adapter. Question is: is using this going to cause any damage to my laptop in the mean time while I wait for my new one to arrive? |

| I wouldn't think that should cause damage, honestly. With a laptop the power supply is less critical, it really just sort of supports the battery. All you'll get is the battery might not charge fully or take longer to charge, depending on how bad the damage is. To be safe, get a new power supply brick whenever you can. And keep the new one away from the dog. ![]()

| In that case, I would recommend you keep the battery charged and use it just until you get a new brick. Direct power into the laptop with a broken lead could cause some damage to other components, they're designed for a certain power, when they don't get the exact power it causes problems.

| No, you just need to be sure the power doesn't come directly from the brick.

Car: '02 Olds Alero, '01 Grand Am, Bus Metro Walk Rep Power: 14 ![]() ![]() ![]() ![]() ![]() ![]() | is the bite before or after the transformer? EDIT: lol i wasn't too clear there, is the bite in between the transformer and the laptop or is it in between the transformer and the wall plug? |

The area circled in blue is where there are a couple of bite marks in the cable. ![]() It's one of these deals: ![]() (ignore the electrical tape beneath it, that's something totally unrelated) I'm not sure this cable is replaceable. Or am I mistaken? Will it just "unplug" if I pull it out? I tried yanking it a little bit, but I don't want to do any further damage. | |||

Car: 1973 GMC Sprint, Buick 455, TH400 Rep Power: 14 ![]() ![]() ![]() ![]() ![]() ![]() ![]() | That end is hard wired into the brick. You should be able to fix it, but you might have to open it up to do it. I'd open it up, cut off the cable past the bites and re-solder it. I wouldn't connect it at all to the computer if it has a short in the cable. You could really fry something, with the battery connected or not. The battery does not regulate the power coming in through the power jack. A separate circuit distributes the power to the computer and/or the battery as needed. At best you could fry that circuitry. Worse, the motherboard or something like that. Worst, you could short the battery and cause it to explode. Plugging in a bad power cable? Bad idea. Period. There's a chance nothing would happen if you used the brick but personally I wouldn't chance it. |

| Yeah if you are seeing shorts I would put the brick away and order a new one. They expect the power for the most part to be regulated before entering the laptop circuitry (the reason why they have a brick in the first place) and causing shorts and etc can not mean good things. If you can tape up the wires (the exposed one individually) , you can repair it for a short term fix. You can fix it, but, again your going to need to cut the wire and shorten it and do a lot of work. It might be cheaper (as in time wasted) to buy a new brick.Since the pic you posted looks like an older dell you can find a bunch of them on Ebay and etc for decent prices. Also, its not a transformer as its not stepping up or down AC, but its converting AC to DC and providing a constant amount of power. | |

I need to get one ASAP because I can't work without laptop ![]() I'll try to repair it. I've done things like this before (soldering up busted wires and chords). It would be easier if I could open up the brick, but it appears that the manufacturer has never heard of "screws".... Last edited by epp_b; December 13th, 2007 at 01:47 PM.. |

. Man that's gotta suck, you can get a new adapter here. But in the meantime, I'd try not to use the adapter with the laptop, just to be on the safe side. | ||

Car: 1995 Nissan 240SX Rep Power: 45 ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | Yeah, I know where to find 'em. Thanks. I just need one sooner than later :'( EDIT: I peeled away a bit of the cable encasing and It appears that the cable consists of an inner cable encasing one wire (- or +, I don't know, but if it "obeys" the specification of the plug, the inner cable should be +) with the outer wire coiled around it. The inner wire isn't chewed at all, so I'm thinking it should be safe just to fix up the bit of fraying of the outer wire and wrap it up with electrical tape. Does that sound right? I just need something to use in the mean time while I wait for a new one to be shipped. EDIT 2: Nope, I was wrong. The inner cable does have one bite mark in it. So, I'll tape that up to make sure the two wires are separated and then it should be good, just for now. Last edited by epp_b; December 13th, 2007 at 02:37 PM.. |

Car: 1995 Nissan 240SX Rep Power: 45 ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | Alright, so I taped up the bite hole on the inner cable with a couple of layers, recoiled the outer cable around it and taped that back up. It's looks shoddy, but I think it will hold for a while, at least until I get it properly repaired or replaced. |
