Question about Medion (40010998)
I'm having trouble booting my laptop. It's a Medion Akoya EX. I'm sure that the problem is my battery. Is this repairable or do I need to buy a new one? All my symptoms are below. If I pull my battery, all symptoms below disappear. I can sucessfully boot and use my system. The left light below the screen on my laptop describes whether the laptop is running from the battery. (Green = laptop is running on battery, off = laptop is not running on battery) The middle light below my screen describes the battery state. (Green = fully charged, off = running on battery power, amber = charging, slowly blinking red = 10% battery power or less remains.) The right light below my screen describes whether the laptop is running on AC power. (Green = laptop is on and plugged in. Off = laptop is either on and powered by battery, or laptop is off.) If the power is off, and the power cord is unplugged, the middle light is off. This is normal. However, if I plug in the adapter, but keep the laptop power off, the middle light starts rapidly blinking red, two times per second. This is far faster than the "Low battery" blink that I've seen before. If I unplug the adapter, then turn on the laptop, the left light turns green as normal. The laptop starts to boot. After 20 seconds, the laptop shuts down. The leftmost LED turns off, the screen turns off, the fan turns off. After this, the middle LED blinks red 12 times rapidly. If I plug the adapter back in, then turn on the laptop, the middle light and the right light both light to solid green. This would generally mean that my laptop is on, powered by AC, and fully charged. However, I experience the same shutdown as above. The laptop stays on for 20 seconds. I can go to my BIOS or start booting from either my linux or windows partition. I don't experience any problems or error messages. Everything works normally, for 20 seconds.
Its late, so just to make sure I'm not brain-dead basically your laptop runs fine as long as its powered by the AC adaptor but dies fairly quickly while running via battery. This is very typical of a battery that will no longer hold a charge, not normally a user repairable item. It could also be that the charging electronics (in the laptop) isn't charging the battery, again not a typical user repair job. About your only option short of taking it to the repair shop is buying or borrowing a battery as a test.

It sounds to me like some of the cells in the battery has collapsed.
A 12 volt light doesn't use as much juice on the battery as when you boot up. When Mobo, Monitor, Harddrive etc etc. start up they all use a large start-up-current and if the battery cant sustain the amount of amp. they all need together, nothing happens.
This is called shadow-charge, the battery seems fine, but when it really needs to put out some power it collapses.
I think you should try to sniff up another battery and see if this one has the same problem.
Or perhaps investigate wether or not you still have some warranty left on the battery, to try to get a free replacement.
