Hey guys,
Im having a problem regarding my hp laptop model is 8470p. 2 days ago i left the laptop on, updating windows for overnight but when i woke up, it was completely dead, no response to power button and kept showing charge white light no matter if adapter is connected or not it keeps showing the charge light. One day i put the battery out and left the laptop overnight, next day when i put the battery again it started working fine but after shutdown the same problem started again, and this time no trick is working. Now, i don't understand what is going on with my laptop please help me out. Thank you.
 
Solution
try this, remove battery & power adapter from laptop, hold power button down for 20 secs(this is a hard reset), reinstall battery into laptop, reconnect power adapter to laptop & turn on laptop.
