[SOLVED] My IBM Thinkpad T20 will not boot up.

StoicBlade · 08-01-2008, 11:58 AM

Hi. I have a IBM Thinkpad T20 laptop. It worked fine yesterday. Now it will not boot up. When I press the power button, the hard drive light and the battery light (located on the keyboard base, near the power button) flicker for a second and that is it. I know that the laptop is getting power from the power supply. I have checked all of the cards to make sure that nothing is loose and I have removed and replaced the battery several times. I even swapped out the hard drive, just in case. Nothing works. Any ideas? Thanx.

Oh yeah, I upgraded to Service Pack 2 about 3 weeks ago.

Try this:
1. remove the battery and unplug AC adapter
2. press power ON button for 30 secs at least
3. plug back the battery and the AC adapter
4. power ON as normal.

EDIT:
Do you hear any beeps? Have you tried running on battery alone or AC adapter alone?

Hey TriggerFinger,

Yup, that worked like a charm. Thanks. I am curious though...why did it do that and why did I need to press the "on" button for 30 secs with no power? Is that a self-diagnostic process or was I re-setting the BIOS or something?

Anyway, thanks for your help.

It is another way of resetting the CMOS configuration. Some laptops have a reset button at the bottom. I believe that is the equivalent of that.
