COMPUTER giant HP is recalling 78,500 laptops due to fears the battery could overheat and cause fires.

The move is an extension of a recall first announced in January 2018, which then involved 50,000 devices.

At the time it said you be affected if you own an HP ProBook, ZBook, x360, Pavilion, ENVY or HP 11 model.

HP has now added 10 more laptops to the recall, as the models are compatible with the fire risk batteries.

If you've bought the products, you should request a replacement battery and apply a software update that switches your battery into a safe mode, which will prevent it from charging, HP urged customers in a website statement.

The extended recall was first issued by HP in January, but the US Consumer Product Safety Commission only announced it now due to a US government shutdown, which was the longest in the nation's history.

The product recalls come after the commission reported HP had received eight reports of the batteries overheating or melting, with one owner suffering first-degree burns.

The laptops were sold around the world between December 2015 to April 2018 for between £264 and £3,526 ($300-$4,000), while the batteries were also sold as separate accessories.

To check if your laptop is affected, you should download a tool from HP's website.

Even if you checked your battery after last year’s recall, you should do so again as it's been extended to include more products.

If it identifies your laptop as being affected, you'll get the chance to put your computer into "Battery Safe Mode".

This will allow you to carry on using your laptop safely by using its mains adaptor instead until a HP technician can replace it free of charge.

Customers are not able to replace the battery themselves, the firm said.

The Sun contacted HP for a comment as well as a clarification on how many of the affected products were sold in the UK.
