I have a IBM A22m laptop that won't boot up. When I hit the power button I see about a 1 second flash in the screen. I tried a different power supply, and took the battery out and put it back in etc. , and the battery light blinks. Not sure what to check next.

A focused troubleshooting note for the IBM A22m symptom described by . rightly pointed at power checks and reported a rare “came back after waiting” outcome; below are controlled, non-destructive steps that isolate display, memory, and power-rail faults so the result is actionable rather than guesswork.

  • Power-reset (controlled): remove AC and battery, then press-and-hold the power button for 30–60 seconds to discharge residual charge. Reconnect AC only and try to power on. This is different from simply removing the battery because it forces a full discharge of board capacitors.
  • External display test: attach an external monitor (VGA) and power on. If the external shows BIOS/POST while the laptop screen stays dark, the problem is the LCD, inverter/backlight, or the display cable.
  • Memory check: open the access door and reseat the RAM modules. Test each module alone in the primary slot (one module at a time). A bad DIMM or slot commonly produces no video/very short flashes.
  • Remove storage and peripherals: detach the hard drive and optical drive and try to boot. If the machine still does nothing, the issue is upstream of the boot device.
  • Observe status indicators: note fan/HDD spin, any beep codes or LED blink patterns and record them exactly (count and timing). Inspect the DC jack for looseness and the board (if opened) for bulging capacitors or obvious damage.

If none of the above produces POST or display, the fault is increasingly likely to be a board-level power/graphics failure or a failed display subsystem; those usually require component-level repair or a donor motherboard. Exercise ESD precautions when opening the case and avoid aggressive repairs if uncomfortable — a local repair shop experienced with older ThinkPads can often give a definitive hardware diagnosis.
