Laptop resolution

The laptop that kept losing keyboard and trackpad capabilities has been tested and a diagnosis made - it was the battery. So yays to me for stating it was a hardware fault after much software faffing.

So to find a new battery. Acer don't even list that model anymore on their "Find your battery" page which is a missed trick as it's more likely for an older model to need one than a newer one. A telephone call got a price of £81.65 inc VAT and delivery with a 30 days delivery window.

Partmaster (Currys, PC World) offer a genuine one for £88 not necessarily counting delivery and a couple of generics one at £70 and one at £75; both apparently identical. Another phone call creates confusion in that they both appear to be the same and both work with this model. I can't tell that because usefully the "Suitable for" section on the list runs out of space and doesn't appear on the main item page. As an added bonus I can't even tell them the items I'm looking at as Partmaster doesn't provide part numbers for either.

You almost get the impression that they don't want to sell anything.
