XPS 15 9550 - Touchpad has become very difficult to use. Probably because of battery swelling as described on numerous posts.

My touchpad seems to have gone up by 3-4mm from its normal position in the past few months making it very difficult to use.

As far as i understand from a number of posts in this forum it is probably related to a battery swelling.

My warranty expired exactly a year ago.

Is this a hazard? Can the battery explode? What is the action that needs to be taken? I really need to have the touchpad sorted out.

Bought it from DELL UK.

Thanks,
