    HP Compaq Presario CQ42 powering on, no display. Missing +3VLCD.
    by gjgib
    Hi again guys. I have this motherboard that won't show display even tho it was doing it yesterday. I think something could've past away in the circuit.
    I'd appreciate if anyone who is used to MOBO LCD voltages and circuits could enlighten me since this is the first time I have to deal with it.

    I'm missing [B]+3VLCD.[/B]

    This is the circuit

    I want to dim light bulb by 50% I want to learn how to calculate it on my own
    by Omron
    I have a 5W lamp on 12Volts battery, I want it to be half as bright, so I will add a resistor. What resistor should I supply?

    A = W = 5 = 0.416mA
    _ _
    V 12


    R = V = 12 = 28.84 Ohms (R) this is resistance of lamp
    _ _____
    I 0.416

    So I will add one resistor 28.84 Ohms

    I will have 28.84 + 28.84 = 57.6 Ohms

    Or 28.84 + 28.84 = 14.42 Ohms

    I don't know if it will work in series or in parallel
    voltage would be 6V and amp current mA = 0.208mA We divide everything by two

    W= V * I...

    HP G3 BIOS
    by AdrenalinTL
    Hi Peeps.

    Quick question. Might sound silly so bear with me pls.

    After flashing a BIOS with a flashing tool, my laptop went from stone dead, to the fan spinning. However the screen doesnt show POST. Is there anything like pulling out the battery AFTER flashing the BIOS one needs to do or is there another issue I am sitting with now?

    I think the board doesn't turn on.
    I have power on directly on the board in SWK001
    External power supply with digital volt/amp and shows 20V and 0.350A.
