My battery is playing up - it has gone through various phases i) charging but not allowing the PC to run without charge (even if plugged in) ii) not charging but working plugged in and now 3) not charging or working typically and then occasionally working even though it says it's flat as a pancake. Conclusion - my battery needs replacing but I can't find a supplier that looks legit. Dell sites won't recognise my service tag (and would probably be cost prohibitive for a machine of this age) and my search for a replacement battery online has just confused me - widely varying pics and dimensions (I wouldn't be able to open my screen if it was bigger).
I have just invested in more RAM and a big clean up and everything is running really well when I can get it on so really don't want to give up.
Any advice and links to reliable retailer very much appreciated.
There's a ton of them on eBay (but a new, original Dell one is £130!) As onthelimit1 implies, most of them are made by Chinese companies. That's not necessarily a bad thing, as the original Dell part was probably made in China anyway. But yes, there is some element of risk. Check that stock is held in the UK, or you'll wait forever, and check feedback meticulously.
