I have a thinkpad T440p, i have replaced the CMOS because it died on me, but now after a while of getting the new one my PC is behaving weirdly, it takes three tries to turn it on. First time i turn it on and it tries to start but shuts off; the second it tries but shuts off much quicker with a strange sound that seems like the speaker suddenly disconnecting and then it works flawlessly on the third try. Is the CMOS the problem here?

    Weird. I have a dell workstation that does the same thing, except the first time all the fans rev up to full speed before abruptly shutting off. Then the second, it shuts off really quick. Then the third, it works flawlessly. I think it happens more often when the comptuer is unplugged/disconnected from power quickly. So maybe it’s something to do with shutting down? That’s a wild guess based on my problem that I definitely don’t care enough to troubleshoot.

    Have you reset the cmos to defaults after changing the battery? It’s very rare, but they can act funky when the voltage droops, but doesn’t dip enough for it to fully lose the contents.

    Also is that machine new enough to have an SOC reset hole? try holding that for 30 seconds if so. That fixes all sorts of issues that makes 0 science to me.

    maybe something physical with the power button? try setting the bios option to auto boot when ac adapter connects, and try booting that way

      Thanks for suggesting this, and yeah attaching it to the AC makes it turn on fine, probably a problem with the button

        it might be getting a charge with the ac and letting it boot up like normal – i would try another battery in your shoes.

          Yeah the battery is barely hanging on, i believe it’s around 50-60%, i was about to replace it but i didn’t know it could cause this. Removing the battery and turning it on on AC works fine. Are the kingsener fine?

        wait, it only exhibits this “3 boot” problem when its on battery? If you remove the battery and just attach it to the AC adapter does it boot on first button press every time?
