    Hi all, just found this site and hope someone here has seen this before.
    Power applied to the unit, yellow led goes on off on then off.
    Press the power button and the yellow goes on off on then off – no green, no boot.
    Hold down the G key to reset, or the Q or P to go into NetXfer, and the unit powers up just fine. (If I hold the K key the led goes green, but nothing happens – btw what is the K key?)
    I am able to reimage with WDM, have tried Win CE 4.2 and 5.0. After the reimage the unit hangs during the reboot, but if I power up and do the G key reset it comes on ok and shows the image was loaded. Everything works o.k. – just the power on issue.
    I am assuming a bad power controller chip (or maybe CPU or bridge chip) but didn’t want to rule out some simple software thing.
    I have multiple units with this problem, so hope to fix them all.
    (of course, if there are any schematics floating around out there…)
    Also, is there a BIOS on these like the S30’s? If so, what key to press?
    TIA.

    ups, did not read the header correct.

    I have never seen such an issue with 3235. I will do a search maybe I can find something.
    These units do not have a BIOS like S30.

    Hi,

    I did a search and this can only be 2 different reasons.
    1. the logicboard is defect
    2. the power supply is not working correct.

    As the first issue is not trivial to test or repair, the second is easily to test.
    Take a power supply from a 100% working unit and test with your failing one. Although the failing power supply is giving power to the unit, it could be that it is no longer delivering enough power. These old power supplies are dying over the years and I have seen that several times with my customers (although other issues than yours have arised there).
