Laptop repairs....

[feral]

Well, it appears the lappy is just about had it :o

I have a LG LS 50a. The laptop has been great and it was at the high range spec wise when purchased.

It has a power connection problem. When I plug the cable in it sometimes connects and I get the AC power symbol and then it flickers and goes on to battery power. If you wiggle the power cord you can get this all day.

According to research ...it has gone and not worth repairing :mad:

1. The connection is on the M/B and it is not easily replaced..i.e. new M/B.

2. The case is very hard to separate as there are no freely available repair manuals for LG Laptops.

3. I have to find the power jack connection...Edit...found one in Hicksville, USA :eek:


What do I do now ? :angrylock:


It is a perfectly good laptop, does what I want it to do and do not want to buy a new laptop. It just unnecessary to dispose it as junk :twisted:

:mad::mad::mad:...not happy but willing to give it a bash :eek:

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 :D:D

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.

AND I HAVE COME TO A STANDSTILL :mad:


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...:twisted:

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 (http://forum.notebookreview.com/showthread.php't=144540)

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.

Thanks for your help Mark & Simon.

I have removed the keyboard as this was replaced only about 3 months ago, and this is one of the easy things that you find on the internet.

I have been searching for about 3 hours now and I just find it amazing that out of the WWW there are only about 10 references to taking the back off.

And no-one answered the question :twisted:

Amazing stats isn't it. I would have though some geek, nerd, noob or tech would have put up some form of service repair guide.

Anyway....back to it ;)
