I am using this forum as i have no other options left, in fixing a Lenovo ThinkPad T500.
The first time, with both battery and power plug connected, or just battery / power connected, when the pw button was pressed, nothing happened (no video, no audio signals, no fan, no hdd, no status leds).
So, i disassembled the laptop, removed all it's components (memory module, keyboard, trackpoint, fingerprint reader, hdd, cd/dvd drive, lcd, wireless, internal modem, cpu, cmos battery).
After a reassembly of the laptop, at power on, status leds are like in the picture below, the cpu fan is running for a couple of seconds, and the hdd is running without the hdd status led flickering, but there is no image on lcd and no audio signals. I tried to power on the laptop with battery and power, just battery and/or just power. In the picture below, there are only the necessary components connected: cpu, memory module, lcd, speakers, keyboard, trackpoint, and also hdd and cv/dvd drive. I also connected a external monitor, but there was no video signal.
As i have no video and/or audio messages/signals, i can't fully diagnose the laptop. I am hoping that someone have had the same situation, or knows what might be the problem.
I would appreciate any help!

Tried that aswell (without memory).
About USB, i really don't know. I can't test the usb ports. Anyway, no devices are connected; i kept it with only standard components connected.

Regarding USBs, check whether their pins aren't bent, check this KB:- http://forums.lenovo.com/t5/R-L-Series-ThinkPad-Laptops/ThinkPad-T400-T500-R400-R500-hangs-on-boot-a...

If there was no beeps when you started without ram, your MB is dead.
