Lenovo Thinkpad T460s not booting

I have searched all forums including this one and have been unable to find a resolution to my issue.

I have had my laptop (Thinkpad T460s) for just over a year now and use it for work daily. I was using it with no issue at lunch, but when I opened the lid around 3 hours later - the screen was black and the laptop seemed to be stuck in sleep mode. I tried a hard reset and now I can not even get the Lenovo post menu to show.

If I press the power button, the keyboard momentarily turns on the backlighting and the power button stays illuminated, after about a minute the power button turns off. This entire time the laptop screen is completely black, I don't see the Lenovo post menu and therefore have no acces to the BIOS or OS.

I have tried using the hardware reset button on the bottom of the laptop, removing the 2 discreet batteries, removing the CMOS battery, removing all batteries and resetting the RAM. None of this has gotten me any headway on resolving this issue. I am going to try contacting technical support but am hoping someone may help me find a quick and simple resolution to this issue.

Re: Lenovo Thinkpad T460s not booting

Try the old trick of removing both batteries and with the AC adapter unplugged:
1) Tap the power button 10 times in rapid succession
2) Press and hold the power button for 30 seconds
3) Re-attach the AC and try to boot
