Genuine Lenovo charger 'unauthorised', G700 not charging

2017-09-28, 6:14 AM

The charger supplied with my Lenovo G700 recently stopped working completely (it was making a weird bleeping sound when plugged in as well), so I purchased another genuine Lenovo charger identical to the first. However, my laptop doesn't recognise that this is an authentic Lenovo product and keeps telling me that I'm using an 'unauthorised battery', so my laptop can only be plugged in, and not charging. So far I've been unable to find a suitable fix on google. I'm reluctant to buy another charger as they are so expensive, in case I encounter the same problem again. 

 

Any suggesions/experiences would be very helpful! Thank you :)

If the original charger made strange noises, you might have damaged the power circuitry on the motherboard

Thanks for your reply! The bleeping sound was coming from the power pack on the actual charger, and happened one day out of the blue, it has never worked since so I haven't used it. If that is the case though, what can I do to fix it? I'm pretty good with computers, but not when it comes to what's actually inside them, haha!
