Laptop will not charge, Battery and charger both work.

Wager ? £10 says it isn't. The cause will be the wrong polarity of charger inserted.

To quote the OP

"Basically I did something stupid and plugged in the incorrect (non laptop) charger to my laptop (Toshiba Satellite C855)"

and

"tells me the charger is plugged in but just losses power until the battery is flat."

What are you talking about??

Perhaps if it was an aftermarket non-OEM power supply, but even then the laptop will have diodes on the input to prevent any damage.

umm , I think the OPs first statement said something like that


it read


"Basically I did something stupid and plugged in the incorrect (non laptop) charger to my laptop"

Correct as I said earlier it's possibly a protection diode (If he's lucky) that has blown, if you exceed the reverse breakdown voltage then BOOM ! It's not a non OEM PSU it's just completely the wrong one which in all likelyhood had the wrong polarity.

Yeah, I reckon it could well be that, I am no expert on voltage at all but can give a breakdown of what I stupidly plugged in (as stated on chargers): Input: 239V - 50Hz 12.5W, Output: 12V, Intensity 500mA 6VA(max)
This is the original adapter breakdown (Model PA3917U-1ACA): Input: 100-240V~1.5A(1.5A) 50-60Hz, Output: 19V 3.42A(3.42A)

No idea if that help anybody but it may do!

It's not the plug jack, I understand it could have been but this is something to do with me being a complete idiot and plugging in completely the wrong charger. It could have been the jack but definitely is not in this case.

Thanks for the help so far too! I know little or nothing about the ins and outs of laptops! There are some motherboards for sale on ebay, could be the cheapest solution perhaps?

It may be possible to repair the current motherboard and it may work out cheaper taking it to a competent electronic engineer who works at circuit level (not a bit swapping muppet) but there are no guarantees your board is fixable.

before you go any further, take charger and battery out, hold down the power button down for a full minute, then release, plug in just charger and see if lappy turns on...

Why doesn’t he try standing on one leg and pulling his eyelid down a bit


For a good similar case history see here, this had a successful board repair.:

!!!!!!!!! sometimes the charging circuits, depending on the design, get latched on/off, this method ensures discharge of capacitors which may be preventing charging happening. And yes, it has worked previously on lappys with such charging circuits...

For the sake of a couple of mins, it's worth trying before looking to repair/replace a mobo.....
