Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Sorry for the delay in responding.
That is a severe error. The first thing to ask is: was the Lenovo dropped, was hardware added to it (e.g. a memory upgrade) or taken from it recently, or was it ever gotten wet ?
Secondly: How old is it?
Good news! if you bought it new, never dropped it nor opened the case (which voids the warranty, generally) nor got it wet by mischance or carelessness, then it is still covered by Lenovo's warranty.
No upgrades? no removals from the laptop?
If no upgrades were done on it, nor anything removed from it, I would advise you to
1. hold the power button down until it shuts Off.
2. unplug from power, remove the battery if it is removable, and leave it to rest and reset, for at least overnight. (or 6+ hours.)
3. try it again.
If at that point it still sticks on the Lenovo splash screen, then it's basically defective within warranty (CPU locked up during initialization, or circuitry too defective to initialize) and you should contact Lenovo about getting it serviced into something like workability.
If you bought it in Australia, then contact Lenovo Australia:
Does this answer your question fully enough?
I hope and trust that they will provide good warranty service.
