Thread: Laptop repairs....

The problem you describe is common with cheap laptops if you can figure out how to get the plastics apart the job should not be difficult.
You usually find dry solder joints on the connector to the PCB resolder and everything is Ok again.
It is daunting the first time but as you say its unusable anyway so you dont have much to loose.
Take a photocopy of the bottom of the machine put blue tack on each screw and stick it to the copy where the screw comes from that way you shouldnt get it wrong.
If you are not careful you will break the plastics I would start above the keyboard then move down the manuals are difficult to obtain by the look of it.

Good luck

Sounds like the power connector on the motherboard has taken a hit.

You need to take the computer apart, and at the least resolder the points where the female power plug attaches to the motherboard, or buy a new one.

In most cases these days, the power plug that mounts to the motherboard of a laptop is a standard part that you can get for under $5 from Jaycar, etc.

If the laptop still runs happily from the battery, then this is just about certainly the problem.

You'll probably need a set of small screwdrivers, and maybe a set of mini torx, although these days most are just small phillips head. It will take maybe an hour to take apart, another to put together, and several weeks hunting around for the replacement piece, finding the bits that you misplaced while it was all in pieces, etc.

Take lots of pics as you go so you can remind yourself how it goes back together.

And I am giving it a bash

The power is not connected to the M/B but to a smaller board like this ...




The power connector is the smaller black box at the top. I have just ordred the part for reasonable price.


So I am halfway there....

The little black thing at the top.

You'll probably need something like a bit of desoldering braid to clean up where the old solder is. Only worry is not to overheat the rest of it while doing it.

I am unable to split the base of the laptop. There are screws or tabs which are keeping the base together near the hinges.

I have removed every possible screw related to the base and it will not come apart.


Ready to walk away...

Lyndon,

Not sure how far you have got, Often you need to completely remove the keyboard from a laptop to split the case.

I found the following that nmay help a little:

Guide disassemble, To change, to replace, the keyboard of its Notebook LG LE 50 Series - Notebook Forums and Laptop Discussion

Cheers, Mark

There are also plastic snap-together tabs around the outside of the upper and lower case. Well, I've never taken an LG laptop apart, but all of the others have had them.

One way to get them apart without snapping them off is to push the blade of a fine screwdriver into the gap between the top and the bottom and push inwards. The tabs are the places that won't push in quite so easily. Subtle, but not too hard to tell. When you get the hang of it they spring open. Start at the corners furthest from the hinges.

It helps if you use your third hand to lever top and bottom apart at the same time. Too much effort and stuff snaps.

The tabs are about an inch and a half or two inches apart. Once the tab/clip has sprung it doesn't usually spring back more than once or twice while taking it apart, and once a couple have opened they'll usually stay opened.

Whatever you do, don't twist the screwdriver or you will scar the case, and it doesn't help much.

You do also usually need to remove the keyboard first as above.
