Some of you may recall my earlier post about the charging (or lack of)
on this laptop. Here's an update, and a question.
I don't have the original adapter (19v 4.74A), so I'm running the
laptop off a beefy HP 19v 7.1A adapter.
1. With no battery fitted the laptop won't run off the adapter.
Press the power switch and the power light blinks once and that's all.
2. With a charged battery fitted and no adapter the laptop will switch
on and runs normally until the battery goes flat.
3. With a charged battery fitted and the adapter plugged in the laptop
will switch on and runs normally for as long as you like. The battery
does not discharge from day to day.
Tests with an Avo confirm that the laptop is running off the adapter,
and is drawing about 3A.
4. Unfortunately the laptop never charges the battery; the charge light
never comes on. I'm using an external charger to top up the battery at
the moment.
Anecdotally the laptop should switch on and run from the adapter
alone, thus indicating that there is a fault in the laptop.
But before I rip it apart I've heard rumours that running a laptop off
the "wrong" adapter can cause strange behaviour.
I think that if an adapter is the right voltage and is capable of
supplying the maximum current required by the laptop and battery then it
should work just as well as the original.
Does anyone here know different?
