Power socket on motherboard broken so bought new one took off old one and replaced it. Now when power on all looks ok, the battery icon looks ok with little plug shown and hovering over it gets charging message. But battery just continues to discharge even with power supply attached. Have swapped out batetry and power supply with known good ones with same result so not problem with either ps or battery. Any ideas as to next step?
Also, don't know if this is a "feature", but laptop will not power up with power supply but no battery. If it did, then I could use it all the time on mains supply without battery. If no solution to first problem above, then any ideas as to how to bypass the battery and use directly off mains?

how exactly did you replace the power socket?isnt it soldered onto laptop mobo? maybe due to loose connection(not soldered enough) dc adapter cannot sustain enough current to run it (without battery) or charge the battery. else you are facing a failing dc adapter try other parts to make sure or have it tested in a local store!
