    Dell Vostro 1540

    I was given a Dell Vostro 1540 with PSU which had not been turned on for a long while.
    If you plug in the PSU (or an identical one) the power light on the PSU instantly goes out ---- indicating a short.
    This happens with or without the battery attached.
    Any suggestions welcome or if anyone has a motherboard please let me know --- it has DV15 CP UMA MB printed on it.
    They are available but not wanting to spend a lot on it .
    Thanks .
    Regards

    This laptop is now up and running but with one annoying feature that I have failed to switch off.
    Everyday at 14.10pm the machine will boot up --- even after being shut down at night - not standby or sleep.
    It does not happen if the power supply lead is not plugged in i.e battery only.
    I have looked at the bios and can't find anything there nor in the power settings .
    Any suggestions appreciated.
    Thanks
    Regards.

    Sorted !!
    Having updated BIOS --- no change.
    Eventually in device manager etc the LAN adaptor was being powered even when the laptop was powered off.
    "Shutdown Wake-on-LAN" was a bit I had missed .
    I had already disabled "Wake-on-LAN" now disabled "Shutdown Wake-on-LAN" has cured the problem although I have to switch on the LAN adaptor if I want to every time the laptop boots -- but I don't use it anyway so no big deal.
    All I need to do is track down where the 14:10pm boot up command is coming from --- suggestions are it is the router
    Regards
