When i boot my laptop, nothing happens on screen, HD doesn't do anything, the only button that is lit is the power button (and the charging button)... I tried with and w/o the battery in...
Up to now, the consensus seems to be that the T23 is
not affected by the BoD symptoms, and your description isn't detailed enough to tell whether you may have such a case.
The BoD Thinkpads I have, and have personally experienced, were/were T21 and T22 models. The symptoms were that the computer would - suddenly and for no apparent reason - cease to boot when the "on" button was pushed, and instead the LEDs for the HDD and power would flicker briefly (less than 1 sec). Often there would also be a soft "plop" noise when the "on" button was pushed. The computer would give no further response.
When the battery and AC adapter were removed and the computer left without power for a period of several days to several weeks, it
might boot the next time the AC adapter was inserted and the "on" button pushed. If it did, this behavior (computer starts normally when switched on) would often continue for a week to ten days. Then, again for no apparent reason, the computer would again stop booting and the above symptoms recurred.
The cause of this problem is presently unknown, although it appears to be related to some problem with one or more capacitors on the mainboard, and therefore cannot be "fixed". The often-made suggestion to replace the mainboard gives a false sense of security, since unless the root cause is known, a "new" (used) mainboard can also develop the problem.
All that being said, the T23 doesn't appear to be affected and if you could provide a more detailed explanation of your difficulty, it might be possible to locate a remedy.
