The RAM installs just the same way in a 3400 as it does in a 5300 (also a 190 & 3500/Kanga). Removing the keyboard and palm rest (to get to the drive) could have further loosened it. I've had a PB 190 and a PB 5300 just sit a stare at me because of loose RAM. Try reseating it or just remove it temporarily.
The same holds true with the power supply board which is located directly under the trackpad and partially covered by the hard drive bracket. A fall could have jogged it loose. Then the process of opening up the 3400 to replace the drive could have further unseated it. There could also be a number of other issues that are causing the problem. It may be just plain broke. The logic board could have a cracked circuit, or the AC connector could be loose, or there could be a problem with the media bay contacts (try removing the floppy drive or CD-ROM) or the card cage could be unseated or...well, the list goes on. Definitely reset the Power Manager after each troubleshooting step. According to the manual, unplug the AC from the 3400, remove the battery, hold the reset button down for one minute (located on the back next to the ethernet/modem port). Then plug the AC back in a replace the battery. HTH, -makmac -- PowerBooks is sponsored by <http://lowendmac.com/> and...
