wow my Hp probook 4530s says "plugged in not charging"!!!!

HP ProBook 4540s 11.1V 8400mAh laptop battery

It happens when you plugged it in to charge the Hp probook 4530s battery overnight and the system doesn't recognize the power supply. The charging light does not light up and the battery indicator on the taskbar doesn't react to the a/c power. Actually you can solve it by unpluging the power to and pluging it back it and it work. after booting to windows you need to put the battery back in and it say the battery is dieing. so it does not know that the power adapter is plug in when the battery is and will not charge. Then step 2 that try to look into is to see if the bios needed to be updated , so please start the bios installer and if it told you that the power adapter needed to be plug in, but the battery is out and the power adapter is what powering the unit. 
Seems to be a problem with Bios not reconizing that the power adapter is plug up and will not charge the battery, also if you plug in the battery and then take it out while the power adapter is plug up it shutdown, does not reconize the power dapter. if you want to get the unit to come on so you can use it untill you get it fix take battery out and unpug power adapter. then plug the power adapter bak up and it should come on. to get it to charge you have to keep puting the battery in and out while windows in loaded and sometime the orange charge light will come on. but once you unplug the power adapter same issue. the bios chip firmware either need to be reinstaled and updated or you bio chip had a defect in it. which HP does know about. If your pc is still under waranty, call them asap they will send out a box to have the unit fix without now charge. just make sure ou bak up all of you data or remove hard drive is it does not voide the warenty
