I've been using my new laptop (Aapire M5-581T) for around 2 weeks and I've noticed something that could become a serious problem. This new computer has been bought from a seller at Amazon as refurbished.
The touchpad appears to be swollen/lifting/bulging. It takes about an hour (I think only when the device is running) before I have to push the touchpad near the keyboard to put it back in place.
I fear that might be caused by the battery possibly bulging. However I don't feel that it is particularly hot and the battery wear level is almost at 2% (which is not so bad) and so far 3 charge cycles. So I wonder...
BTW, I've completely charged the battery once using a powerbank for laptops (which can deliver 19V current). Otherwise I've been using the device with the AC adapter.
