The Samsung Netbook is back with Mr Fixit. The charger has been checked and is delivering the right voltage, the pins on the motherboard are also delivering the right voltage - so the problem must lie with the new battery... so the Gorse Fox left it with him to get replaced and checked out.
On a brighter note, the chappie came with the stand-in Nespresso machine and took ours away to be fixed. At least GF should be able to get his fix! Unfortunately the replacement doesn't have a milk steamer/frother so the Silver Vixen will have to rely on copious amounts of hot milk.
