Repairing a laptop power supply

jank

I am looking into repairing an LG laptop power supply. The OH dropped it not so long ago and I think this cracked the end point connector of the power adapter. Now I have an similar power adapter which is an IBM and the connector is a perfect match for the LG but the amp's output are totally different. I thought this would work but no luck....

Anyway, I am thinking of doing a self repair on this adapter by cutting a piece of wire which the good connector is attached to from the IBM adapter, cutting a part of the wire off the original adapter and replace with the IBM one. Kinda of a swap over if you get me.

I have found this.

Now not exactly what I am doing
I basically want to wrap the 2 copper wires over each other via an overlap and then get a **** load of duct tape to make sure it is not exposed and it wont come apart.

Anyway, do you think this will work?

I think you'd be better off buying a new adapter tbh. Check ebay. Defiitely not worth the hassle repairing a broken one.

You need to match the voltage out put of the new power box to the old one also the current output. Then you need to find out the polarity of the power supply, is the outside connection 0 volts and the inside positive or vice versa.
I had an old Packard Bell laptop which had a problem with its Power supply 2 years ago and I had to but a generic replacement with a multitude of pluggable connections fro a wide variety of laptop makes, it never worked longer than 3-4 months at a time needing replacement and resoldering of the DC connection. Then the connection in the laptop got loose and wouldcost€100 to fix, not worth it. Once they start giving trouble they are very difficult to fix propperly

Agree with the posts above. Check ebay ya'll pick up the one you need.

The reason it broke was from all the thugging and moving the adaptop receives. Repairing it will only last a short time and you'll need to repair it again and again. As a tempory fix go ahead and repair while you wait for new adaptor to arrive.

Would like to get a new one but I got the Laptop in Singapore and I am in NZ at the mo. Got in touch with LG in Singpaore and they are saying a that the adapter will cost $45 but to send it to NZ will cost $240..!!!

Hence why I want to try and do the cheap repair. ebay does have some fake ones that claim to work but not the LG ones.

Any more ideas? Anyone can buy a new one but would like to try a repair for a change.

Buy universal charger on ebay. It will cost you only €12 shipping included.
That is the cheapest solution

kikel

what the brand on the charger itself. Is it LG or someone else? Let me know, alot of these chargers can be universal. Also get me the required output Volts and Amps?

jank

The brand is lin shin international enterprise corp
output is 20v, 2.0amp

No Duct Tape, whatever you do. Electric or not at all. Not insulated as well, and much more of a mess.

Doesn't seem to be a popular model.

Maybe this would work. Ya would need to verify this pin size. But I'm guessing it would be a match. I'll make further enquiries for ya Monday

Ive made a few frankenstein PSUs over the years, but tbh, unless you know what you're doing I wouldn't bother. It can be fiddly and is usually hit and miss.

I would just buy a new one, something decent, and it should last a good long time. Definitely don't just for the cheapest possible one you can find, it'll be a false economy in the long run if it breaks again.
