A lot of laptops will run fine on a MSW here are some items that do not run well on a MSW.
Laser printers, photocopiers, magneto-optical hard drives
Certain laptop computers (you should check with your manufacturer)
Some fluorescent lights with electronic ballasts
Power tools employing "solid state" power or variable speed control
Some battery chargers for cordless tools
Some new furnaces and pellet stoves with microprocessor control
Digital clocks with radios
Sewing machines with speed/microprocessor control
X-10 home automation system
Medical equipment such as oxygen concentrators
I suggest buying a Kill-a-Watt Meter
Power factor displays:
Volts
Amps
Watts
Hz
VA
KWH
I use the volts & Hz to adjust the governor on the Onan 2800. If your generator surges it's quite likely running too slow, and the voltage, and frequency will be affected. It seems my needs a little adjustment a couple times a year.
You can use the Hz, to check the frequency of your microwave while running on the MSW inverter. Should be 60Hz, but you will probably see something in the 50Hz or even 40Hz range.
