Hello everyone, nice forum do you have here - sorry about bumping up an old thread, but, I thought I shouldn't start a new topic, as my problem somewhat coincide with the main theme. And here it is - I bought second hand faulty T23 few months ago, seller said it was something with motherboard, but that was ok with me, since i needed just tft panel for my old T22 which had some pressure spots on it. Nevertheless, I thought I should give it a try - so i hit the power button, and CPU fan started spinning (steady, without surging), but not much else, no signal showed up on display, neither HDD showed signs of life. I replaced the keyboard with the one from my old T22, and bingo, it booted! However, after i rebooted it some ten minutes later, it went dead, and wouldn’t boot again. Now i searched the Internet for some guidelines, found your forum, and learned that most commom problem with T23‘s motherboards is associated with loose iductors. I dissasembled it, and indeed, there it was, the one in the area underneath the space button had the hairline crack on the solder joint, and i easily took it off. I’m not so versatile in soldering so i took it to friend who works as a computer repairman. Now, he resoldered the inductor, though i think that he had not cleaned the places where inductor was connected to the board, which were lightly coated with black film, but tested it afterwards and said the conduction was good. I assembled the computer again, but it acted just like at the beggining - “Z” button lights up, CPU fan spinning, no display signal, no HDD activity. I should try again the trick with the keyboard (although i feel that was coincidence), but at the moment i don’t have my T22 with me. Any other ideas and advices would be greatly appreciated. Cheers - and sorry for my poor English!
