I confess; I’m chicken. I need a new battery for my Toshiba Satellie U200, so off I went and Googled for it. This is what online shopping should be for, after all: I can type in the part number of the laptop or the battery and get many pages of hits, all striving to garner my business with promises of guarantees, instant shipping, perfect compatibility… what could possibly go wrong

Well, take a look at pictures of the U200 Tosh. It has overhung screen hinges – by which I mean, when the screen is opened any further than about 50 degrees, the base of the screen starts to drop over the back of the laptop. By the time it is open at a sensible laptop viewing angle, the screen base is aligned with the bottom of the main body of the unit, and completely obscures the rear of the laptop. That’s why all the plugs are on the sides and even the front: the back is completely occupied by the battery.

So… why is someone selling this? – at first blush it looks like a jolly good idea. Extended battery runtime is an excellent concept, and hanging outside the form-factor of a laptop is a tried and tested way to get it. Having a standard battery dock in many models of laptop no doubt helps manufacturers keep prices down, too – but as with so much “should be easy” stuff on the web, it looks like this is one of those howlers it’s all too easy to get caught by.

I actually sat here for a few minutes, waggling the screen of the Tosh to and fro for a while, trying to figure out if the lid could possibly miss the bump on the back of the battery – then I realised it was much easier to confess to moral turpitude here and wait for someone to recommend a battery replacement website which actually knows what they are selling.

(by the way, no special criticism is intended for laptopbatterystore.co.uk – they are just one of the hundreds of sites all apparently using the same copatibility parts matrix to offer the same batteries for the same laptops)
