motherboard charging troubles

Hi all got in this week a cf28 800mhz barebones with a broken jack plug. No probs new one soldered in fairly easily, however runs fine off a battery pack just wont take a charge with or without a battery cell inside??

Funny thing is stripped it to ohm out the fuses and seems to not have an f2 fuse the one by the hard drive connector is this related or am I a million miles off as usual.

Hope some can help in this ever growing fountain of knowlege that is the panasonic part of notebook forums

stoke7up, i've repaired other brand laptops, and one of them after replacing dc jack still didn't power up, which is what i think your trying to say?? so i measured voltage at ac adapter-good reading. then barrowed a known good one and it fired right up and worked great. the bad jack must have shorted it out and fried the ac adapter-good luck

 

Hi the laptop will power up if i take another charged battery and put it inside, however if i try to plug the ac adapter aand charge the battery in situ it registers nothing..

The ac adapter is good tested on other lappys and the battery is good same situation

Any ideas ??

 

It could nbe the fuse that you pointed out. Can you take a picture of it and post it here. I have a zillion mobos to compare it to... Let us know...

 

I think someone is trying to repair that mbo. before, and he/she probably failed. Replacing the dc jack is not easy contrary to what you have mentioned. One mistake it will not power up. The surface and back portion area of pcb pin hole with dc jack must me soldered properly and look for a proper circuit line on pcb that is connected to the dc pin asignment.

Have you had any luck with the new AC in plug? Spark
