Thanks. Tried that, but no luck.The flickering lasts about a second then it flashes each half second. The external monitor remains black.I now suspect the Cmos battery or related. The laptop is from 2014 and has been running almost 24/7 every day since then. Actually I'm amazed the HDD has lasted this long!Sent from my Galaxy

You could try connecting an external monitor in case the problem
is onboard display. If you are seeing some LED flickering due to
disk activity, that could indicated that you have progressed
beyond BIOS initialization and are into the OS boot sequence.

My laptop, a Lenovo y50-70 black screened
yesterday, I presume during an automated windows update.
It wont boot and I cant even get into the bios to
see what's up. On boot a few leds go on (power, battery) the
disk light flickers for a 1.5 seconds then flashes on and off
each second. No other response.
Lenovo doesnt seem to have a copy of the bios code
I could download and reflash my bios with.
Any ideas?
I am presuming that the bios is corrupted. Does
anyone have suggestions?
