Last evening, i closed my tx2500z and let it go into sleep mode for the night, not plugged in. this morning, i plugged it in (power light still blinking for sleep mode), but didnt open it. after work, i came home, opened the computer, and it wouldnt come back to life from sleep mode. i though it was odd, so i just hard-reset it with the power button. it wouldnt boot up though. not even the hp logo, not even bios. all it does is makes the cd drive sound twice (not the usual 3), and continually blinks the capslock and scrolllock LEDs. ive tried with the power cord, without the power cord, with and without the battery, with and without the cd drive, held the power button with everything detached, pressed all the normal buttons (esc, F8...) and nothing. im clueless and would appreciate beyond belief any help. thank you!
