Well the one in Birmingham never arrived - place wouldn't answer any emails or phone calls so I requested a Paypal refund. They issued a refund straight away, by which time I'd found one on Aliexpress (a bit cheaper, too, at £30ish) so I ordered that.
A week later the Birmingham place emailed me and said they now had it in stock if I wanted to reorder it. I ignored the bastards.
The one from aliexpress was marked as dispatched within a couple of days and I even got a tracking number! Then the merciless Chinapost took over and it's spend the last 6 weeks bouncing between the airport, customs, security and the seller - back and forth, back and forth...
Contacted seller and they gave me a refund.
So I had an other search on google, this time I found a place in Belgium that reckoned they had it in stock ready to sell - so I broke out Goolge Translate and attempted to order. The site was weird and kept stopping responding randomly, but I persevered and managed to get it to accept my order on Wednesday. It just turned up in the post, and for the grand total price (including postage) of 12 euros!
Just have to fit the fucker now, but if anyone needs spare laptop parts I can heartily recommend
