Question about Medion md40298 Notebook
1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
4. The motherboard could be defective & needs to be replaced.

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.
