B&D 400W Inverter won`t run my laptop

The inverter is definitely working - have tried with phone charger and a reading lamp. the voltage supplied is reading just over 200V so maybe a little low but these devices seem fine with that. The laptop i`m trying to run is 19V 6.3Amp so should only need 120Watts max so i`d expect a 400W to manage easilly but all i get is the inverter power light flashing. i`ve tried seperately with 2 full charged leisure batteries and still no luck. Anyone have any ideas pls?

Your numbers don't add up. Where are you 'seeing' 200volts. Your lap top power supply transformer uses 120 volts AC. Are you plugged into a 240 volt outlet or something? Your inverter should be 12 or 24 volts DC input; to AC power usually 120 volts AC. Check out you output plug, should read 110 - 120 volts AC

Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

400W Black & Decker Power Inverter Doesn't Power My LCD TV
The problem of your inverter is from
your battery .your laptop and dvd
player requires little current to
operate.But you tv requires more power
to run, if your battery is low you it will
not last for 3 minutes. If your battery
has a low current rating, it will also be a
cause, for example, if it is below
100ampere hour. Lastly if your battery
is bad i.e. if it reads below the
stipulated dc voltage Require by your
inverter to operate.
