Sony have issued a warning that some of the batteries in their Vaio Fit 11A laptops could set on fire.

If you have one, you've been advised to stop using it immediately.

Sony say a non-removable battery pack built by Panasonic is to blame and, in a statement, they said: "The safety of our customers is of the utmost importance, so we are advising those with affected models to switch off the unit and discontinue use."

"We have provided customers with a simple tool to check the serial number to identify whether it is an affected model."

The Vaio Fit 11A has only been on sale since February, so it shouldn't be too big of a problem.

Affected European products are:

SVF11N16CTB SVF11N1L2RP
SVF11N1A4E SVF11N1L2RS
SVF11N1C5E SVF11N1M2ES
SVF11N1L2EB SVF11N1S2EB
SVF11N1L2EP SVF11N1S2ES
SVF11N1L2ES SVF11N1S2RS
