    Dell inspiron 15.led light on,does not power on,just one funny sound every 3-4 secs.

    I removed everything hook up to the board and still does not boot up, power led stays on but does no go beyond that, nothing on the screen, just one blocky sound coming from speaker.
    i attached the schematic, maybe some of you guys can help me.
    so far i notice that the drain side of PQ702,PQ703,PQ700 line is shorted to ground.

    What type of sound?
    Did you go through bios beep codes?

        no solution yet, still doing the same, im thinking it might be embedded graphics chip/processor.

          it doesnt go to bios , not even the dell logo. and the sounds are not beep codes, its a single screeching noise coming from speakers....weirdly enough the laptop stays on the whole time, never shuts off.

            did u tried to flash the bios by removing the eprom chip and flasing by flaher/eprom programmer and putting it back on motherboard, many forums says that its a eprom bios error, a common issue with insyde UEFI BIOS program especially on dell 3521 series.

              if it sounds like 'tek' 'tek' then try flashing BIOS.
              Generally 34XX and 35XX series have this problem.
