Serious Power Issues

Fellow NBRers,
Let me start from the beginning. First power cord got melted in two by exhuast heat. I sent my notebook in for service. Second power cord went down from having its tip burned/melted to a black "crisp". I now received my latest power cord today. When I plug it in, my taskbar notifies it is on ac power for slit second, then says it is back on battery power for a second. Under my ATI PowerPlay settings, it says it is on ac power everytime I checked.. My battery is now down to 0%, but somehow this back and forth between ac/battery is keeping my notebook alive. When I remove my battery, I lose all power. The ac adapter can not power my notebook solely. It is dependent on the 0% remaining in the battery to keep the notebook powered. I have seen my share of problems, but this one has me stumped. My notion is that my laptop has a bad power adapter where the cord plugs in. This would mean a trashed laptop. Is it possibly a bad battery? If so, then why can I not power my laptop solely on ac power? I think my laptop is trashed. I can only run it plugged in.

Thank you for your help!!!

EDIT: I have pinpointed the problem to be a faulty ac plug in my laptop. I need to fix it somehow.

 

well.... you left out the most important part...

what model of laptop are you useing?

 

well i feel that its something to do with the laptop rather than the poer cords supplied
they may need to replace your obo or ap art of it that is connected to the power cables if im correct

 

V2000Z. Review below. Processor extensive apps like overheating this area tremendously. So hot that my computer may freeze up, then causing the screen to go blank, thus turning the overworked fan off. Youtube videos are somehow currently the only thing to cause the freezes. I am currently able to charge it with the adapter in the laptop at just the right angle. We'll see how this long lasts. What needs work?

 

if you can get it to work using the move it around till you hit the sweet spot...

there can only be one issue...

the power plug on the motherboard is no longer soldered. the high temperatures have caused it to melt away the stuff keeping it in place...

because of this now the parts touch but just barely causing small arcs of electricity to form... causing even more heat...

GET IT FIXED PRONTO....it's an easy cheap fix at an electronic shop... all you need is to solder it back on firmly.... if you keep on using it like this you might burn out your MB completely...

so it's NOT the power cord... BUT the power jack INSIDE the laptop....

 

samov,
You really know your stuff. Your answer sounds spot on. I got a $260 quote from Altex. I little rich for my blood. This sounds like my first DIY soldering I have ever done. I'm going to Lowe's later today to buy a mini screwdriver set and a soldering gun. Are there any tips you can give a first-timer?

 

Yes, get a good soldering kit, unless youre an expert who can do thsi stuff with your eyes closed get a quality solder. if u can buy one with a temp reader thats good (but itll probably cost alot).

also practice soldering stuff before you dive in, unless you wanna risk causing more damage to the board.

 

i recommend you search for an experienced person... just to make sure it is a good job...

PLUS... you are tampering with electronic components so you need a special solder so that it does not discharge on your compenents...

there was a whole generation of laptops with this problem.. it's fixed on the newer models but does happpen from time to time... mainly to toshiba

hope you get it fixed... best of luck

 

I am having trouble finding a place that will solder. I called Totaltec, but was told they do not solder there. I was referred to Mr. Notebook. They told me I needed a replacement ac plug for my notebook. They told me only their Austin location carries the part. I was referred to Altex who gave me my only quote. I am headed back to Mr. Notebook right now for a quote. I'll keep you updated.

EDIT: I opened my notebook up today, but could not find issues with the six enernal pins holding the ac plug to the motherboard. I guess that's what the experts are for. Off I go to Mr. Notebook!
