i am using lenovo laptop for very long time, like in 15 year i have used 4 lenovo laptop becuase they are cheap and abundant.
there was this issue with the touchpad... in one year i had to change the touchpad three times, it was due to charger and touchpad getting short or something ,, now i have never seen this in Asus, HP, Sony laptop.. no matter how we use it
but Lenovo Laptop some models are designed disastor, the voltage on some touchpad are very bad .. i sent several emails to lenovo, they acknowledge it,, but have no solution....
