Hp notebooks are really  unreliable.Dv4(dv1225dx) doesn't boot, just gives blank screen  all led's are on  except caps/numlock  leds are always blinking. Perhaps motherboard failure  I think, any other solution ?

    Sorry to be the bearer of bad news but I had similar light sequence on a HP Compaq 6730s.  It turned out to be a motherboard failure.

    here my laptop troubleshooting guide :
    - if no display - test with an external monitor
    - test also with a known good battery !
    - remove battery and AC adaptor, hold power button for 20 sec, connect AC and reboot --> any display ? if NO -->
    - disconnect all disk and cd drives, battery , and other cards and peripherals, leave only 1 ram stick
    - boot -->any display ?
    - if NO remove all ram and reboot --> if NO beeps, mobo or cpu bad ; if it beeps, replace ram stick
    -if you can access the bios battery, remove the battery, AC, and bios battery for a minute to reset the bios
    or test it, it should read 3 V
    *** you can test the disk on another pc, if you like !
