Tests

Here we are again. I did some tests on voltage at some other places. And guess ... still voltage! At first I tested laptop @ home, there i got 83.8v (laptop not running).
Today I tested my laptop @ another place (another city).
Laptop Off: around 80v
And then I booted laptop. Voltage went up to 100v !!!!!
After booting voltage was around 95volt.
Then I connected my usb printer back to my laptop, and no more voltage ... This means if u connect a USB device to your laptop it gets around 90volt on it and it uses the usb device as a ground! Hope this doesn't break my usb devices!
