M17X R2 Charging Problem FIX!

Hi,
I'm a proud owner of the m17x r2. For a while my laptop has been plagued with power outtages

The issue began with a few "plugged in, not charging" here and there... developed into "this plug is not oem" then it got so bad that i had to apply keep on unplugging and plugging and moving around the plug, etc..... which naturally made me think i had a bad dc jack.
After changing the motherboard (for a different reason), I realized that it's impossible that the motherboard is the issue as i kept on suffering from the same problems. I narrowed it down to the brick. Sadly, it costs 80 bucks on ebay and I just came out from a round of upgrades on my desktop and on the m17x r2 as well as paying my school fees and buying a new car. I WAS BROKE. So I was determined to fix it my self.

I've noticed that this issue appears usually when im playing games and the computer is consuming a lot of electricity and I figured it might be the soldering. I cracked open the brick, tested it, only to find out there is nothing out of the ordinary.
This led me to believe that it was the plug that was faulty. I have seen it in my qosmio and I figured that might be the issue.
I removed the rubber off the plug using a remington knife and found two soldering spots. One was a metallic object and the other a red wire. I removed the old solder, and resoldered it.
This was a week ago, I haven't had any power hiccups ever since.

I attached a photo of how the plug finally looked like....

I just want you guys to know that you don't need to shell out 80 bucks for a new brick and if you still want to just replace the brick.

Also, If your computer doesn't charge, before doing this, try taking out the plug and battery and press the power button for 20 seconds or so. This should drain all the static electricity inside. Now put the battery and plug back into the machine and fire it up. If that doesn't work then try this method and hopefully it will work.

 

Wow, definitely a macgyver job there.

 

i had this problem before, sometimes I needed to do the hard power down to enable the charger.

Last week when I was having an issue that stalls at shutdown state, i have learnt that when you upgrade your BIOS to A10 (I guess A09 should work), this problem is no longer persist.

 

Yes I do realize that there is the bios issue and then the hardware issue.
I thought that I had the bios issue and reflashed the bios many times but nothing changed.
What I'm saying is, if you tried everything and nothing worked, chances are, it's the soldering.
take care

 

This is @ rin_Two07. Hey, so I tried this out on my flextronics 240w adapter. Been getting some major throttling on the different components due to insufficient power. I don't know if I permanently ruined my machine.. or whether I did it incorrectly. Everything looked ok inside the little plastic part on the charger end that sticks into the back of the alienware. It was a real MISSION to get that darn plastic off.. I think the point at which I must have ruined everything was when the cutting wasn't working anymore and I decided to with a soldering iron to melt away the plastic on the end. Now the little blue light is disfunctional, and worse still the problem remains the same. No charging. I'm relieved to know that my soldering didn't completely suck and that the charger still works enough to run the m17x r2 without battery.

Can you draw me a diagram of how you ended up removing and resoldering the red and black wires inside the charger end?

Thanks
