    I am having problems with my laptop powering on. I plug in my AC adapter and the charging light comes on I then try to power and the power light will come on and then just go off. When I have opened the laptop it seems the fan doesn't kick in at all.

    I have tried the following:

    Different charger
    Took battery out and held power button
    Checked ram
    Disconnected keyboard/CD drive/ hard drive
    CMOS battery
    Cleaned fan (making sure it will spin properly no dust blocking)
    New thermal paste

    I have no idea what to try next, any suggestions would be great.

    What's the complete model number of that Toshiba Satellite L450D laptop?

    There should be a dash and another series of numbers and letters after L450D

    ---------------------------------------------------------

    How old is that laptop?

    The battery doesn't last forever and will lose holding a charge.

    ----------------------------------------------------------

    Is that replacement charger the correct wattage and voltage?

    L450d-113 is the complete model number. It's a genuine charger that I bought. Also even if the battery doesn't last forever, surely the machine will power despite having a battery issue/if it's removed while the AC is plugged in.

    The board is certainly getting power to it and correctly. The fan doesn't seem to start. I have also tried replacing the CPU and still no luck. I am thinking of putting it down to a bad motherboard.

    According to the Toshiba Satellite L450D-113 support site, it uses a power adapter with these specs:

    Input Voltage: 100/240 V

    Output Voltage: 19 V

    Output Current: 3.95 A

    Output Wattage: 75 W

    -------------------------------------------------------------

    I've worked on a couple of Toshiba laptops that had "power on" and charging issues.

    Replacing both the battery and power adapter resolved it.

    But like you said, it may have some other hardware issue.
