No, however, I think the adapter is faulty, voltage is fluctuateing

- bad jack on the netbook
- dirty battery contacts
- bad battery
- bad charge circuit in the netbook

Will it boot with the charger plugged in and the battery out?
>> ...voltage is fluctuating

yeah, that's not a good sign. Anyplace to test what the adapter does with it plugged in and you try to turn the netbook On?
I doubt the adapter will come apart, but maybe through the cable, of if the netbook isn't too much a pita you can gain access to the inside of the jack.

If you can beg, borrow, or steal, another adapter, that would be the easiest way, though.
If you have time to wait for shipping from Asia, a replacement AC adapter can be had for under $10 through eBay.  Universal ones (lots of different connectors for different laptops) can be had for around $30 in the US, $10-15 from Asia.

If time is not the issue, this is a pretty inexpensive way to identify if the adapter is the problem.
