My little Acer V3-112P laptop has been round the world with me but recently developed a fault. It started making a ticking noise (like a capacitor discharging) when it was charging with the lid shut. Unfortunately then the screen stopped working but shining a torch on it showed the back-light had failed.
According to Acer’s support page, static electricity can build up in their devices. I’m turbo this week so I guess I’ll be taking apart a laptop this weekend to see if I can get lucky and it’s just a capacitor that needs replacing.
Edit: Apparently Cold Cathode Fluorescent (CCFL) back-lights are no longer popular and most screens (including this one) have LED built into the screen. So I’m waiting on a replacement screen.
