Charger for Asus Chromebook

Jun 3, 2017 12:58PM PDT

Hi all. I bought an asus c300m chromebook cheapish on ebay and it came without a charger, as described.
I figured I could just botch one together, so I found a plug that fitted the chromebook on an old charger, cut the wires and soldered it to a 19v 45w charger I had knocking about. I checked the voltage and polarity with a multimeter and as it looked fine, I plugged it it. The charging light on the side of the chromebook goes to a steady red, and the charging icon in the system tray says that it is charging. But after an hour, it is still on 5%, still saying 12 hours until charged. Is there something about laptop chargers I've missed in my attempt to bodge something together!
Cheers Guys

I guess

I guess I'll return it if it won't take a charge from a real charger. Just wondered if I'd done something stupid as the charger I dismantled had three leads, at 0V, 12V and 19V, so I thought there might be some weird about laptop chargers. I just connected the 0V and 19V wires to the power plug. It's not like it was dirt cheap. It was £70 which is only about ten or twenty quid cheaper than they go for so it wasn't exactly to good to be true.

Three leads is a big huge clue.

To stop using any old power source the chargers are special. I don't want to duplicate the old stories here about battery fires and what design changes followed.
