Notebook Shutdown / Hybernate without any warning

If your notebook shutdown or goes to hybernate without any warning then your notebook might be getting over heated and you should avoid using an overheated system as it might fry some other parts.

Please check your systems temperature with some software like speedfan and see if its under the operating range of your peocessor or not.

Generally speaking AMD processors have a much higher cutoff than intel as they become much hotter than intels.
