Am back again, I have a power supply rated at 12v 2amp output.
This came with a new laptop, but when the battery in the laptop
is showing 100% charge, the voltage displayed is 8.4
Is it normal for the battery voltage to be this much lower
than the power supply output.
The specs for the laptop state 12 volts, this is why I bought it,
so I could plug it into a car battery with some diodes to bring
the voltage down a little and a 1.5 amp fuse to protect things.
Or do I need to find a 12 volt regulated power supply keeping
in mind I need this to work off a car battery / 12v
I have yet to test the power at the charger outlet to confirm 12 volts.
