I have exactly the same problem with my T400. Computer was working perfectly... I did a reboot... and never boot again.. it hangs at the initial boot screen, but neither the "ThinkVantage Blue botton", neither F1, F2 or F11 give me access to bios or any further info. No post messages on screen indicating if any hardware failure... nothing...
Any hint ?

Just a WAG:
Remove the battery, and power with the AC adapter.
What indicator lights are on or blink, and which are off?

This just started happening to one of my users on Sunday. I had him overnight the laptop to me and indeed it freezes at Lenovo boot screen. One odd thing I did notice is that the wireless switch is off, but the Bluetooth indicator is on when the laptop turns on. The only other indicators that are on are "Power On" and "Battery status".

Here is a sequence that might help fix delays / hangs at BIOS POST:
EDIT: Mark_Lenovo recommends skipping the gray steps 3-5 when you first try this sequence -- they may not be necessary. If you then decide to try removing the CMOS battery, please first make sure that there are no administrative passwords set on your ThinkPad.
Please report back if the above works for you. The above sequence does the most thorough reset of your machine, it's possible that not every step is necessary. If you're squeamish about opening your ThinkPad and don't have someone to help you, you could try skipping steps 3 - 5.

Welcome to the Lenovo forum!
Sorry to hear of your trouble with your T500. If you're able to get into BIOS Setup by pressing F1 at boot, you could try disabling the Security Chip: Select Security, then Security Chip and set it to "Disabled", then press F10 to save settings and reboot.
If you cannot get into BIOS Setup, or the above doesn't help, it's probably time to call Support.

Unfortunately, can't get into the F1 BIOS settings (tried to press F1 and hold it before, and press it at different times after, the power-on button, without any luck)...
