I put my Experia Z on charge and when complete removed from the charger but the green light remained on and I cannot switch the phone on. Help!
Try holding power + volume down for 15 seconds and try turning it on again. Additionally there may be a red reset switch near the sim tray area, not sure which model had it but it’s worth a try.
Xperia Z has a removable battery if my memory serves me right. Take it out, leave it around for like 2-3 minutes and try turning it on. I still own a Xperia L as my secondary phone. I just love the phone, never felt like selling it off
