For 's T22 that shows power LEDs but never gets to video or a boot screen, 's point about listening for POST signals and 's experience with a failed drive are both relevant. Those two leads help narrow the fault, but a quick, ordered check will separate a simple user-serviceable issue from a board-level failure.

Recommended quick checks and isolation steps:

  1. Confirm the adapter and battery: verify the power brick LED and, if possible, measure output with a multimeter. Test with AC only (battery out) if a spare adapter is available.
  2. Do a power/EC drain: remove battery and AC, hold the power button 30 seconds, then connect AC only and try powering up.
  3. Memory: remove SODIMMs, clean contacts, then try one module in the primary slot. Faulty or poorly seated RAM often stops POST.
  4. Display vs POST: connect an external monitor (VGA) and also shine a bright light at the LCD to look for a faint image. External video or a faint picture points to backlight/inverter or lid cable problems.
  5. Storage isolation: remove the hard drive and power on. If the BIOS/POST appears without the drive, the drive or its controller/MBR is implicated. If nothing changes, the HDD is unlikely to be the root cause.
  6. Observe fan, LED blink patterns and any beeps; document them. No fan/spindle spin plus LEDs often means DC rail or motherboard faults.

If these steps do not produce POST or any diagnostics, the problem is likely motherboard/DC-jack/EC related and needs board-level repair or a replacement unit. Handle modules with ESD care and consider professional service if unsure.

Try a different hard drive. I recieved a T22 for christmas and a few months after my hard drive failed and made the machine do all sorts of weird things. But IBM was quick and had a new drive to me in a few days (machine was still under warrenty).
