HP ProBook 430 G3 Notebook PC
Microsoft Windows 7 (64-bit)

Just out of waranty Notebook (430 G3) shuts down without warning. This occurs now a couple of times each hour. No warning, no messages, just switches off. Powering on again and Windows starts up again as normal (no warning about irregular shut-down or similar). This is not a heat issue (have run Speccy and all temperatures are below 40C). Have run start-up diagnostics and all seems OK. Any ideas?
