I have a question concerning power issues with a Toshiba satellite m35x 109. From all my reading, who hasn't had power issues with this model. Infact, all material I have found concerning disassembling this model was for the purpose of repairing the power jack. I am no exception. I fixed/re-installed the power jack to the motherboard and when hooked up to AC, I have an AC and Battery Charging indication leading to 100% charge....providing that the laptop is turned off. Once I turn the laptop back on, I still have an AC power indication but my battery is not being charged and is infact draining. Once the battery returns to zero, I get an annoying low battery warning tone (which I beleive I can eliminate in the biosbut defeats the point). Could it be that the power adapter providing the DC current might be going low and cannot handle the load of both the laptop and the battery, or, is the battery going bad and has excessive internal resistance providing too great a load? Or something else? Thank you so very much for any assistance!
