How would you know if power supply surged in my 110v toshiba e-studio283 because it might plugged into 220v by the operator?

Question edited for clarity (make model (what it is)

Just buy plugs to suit the voltage for your bench use.

• AC Output:
  • 110V Version:110V~1.4A 60Hz, 150W, 300W Surge
  • 220V Version:220V~0.68A 50Hz, 150W, 300W Surge
• Cig Lighter Port:12V=10A, DC Output: 12V=10A (Total 120W Max)
• USB Output:5V=2.4A, 12W Max Each Port
• USB QC Output:5V=2A/9V=2A 18W Max
• USB-C Output:5V=3A/9V=3A/12V=3A/15V=3A/20V=3A 60W Max

hi
does it allow you to switch from 110v to 220v ? if it does then you got to switch it according to the power supply from the plug point that you are going to plug it into. Do NOT switch it to 110v and plug it into a 220v plug point .
if it is only 110v and not switchable then you got to use the only 110v

Have a look on ebay for cheap converters:

if you need 110V US to 220V UK (6.99):

or 220V UK to 110V US (3.00)

Hope helps

While most modern power supplies can handle such a mistake with minimal damage to the motherboard and attached computer components, there is still a high probability that you damaged a component on your computer.

The only surefire way to know if you caused damage is by testing; so it is suggested that you obtain a new power supply, set it on the proper setting, plug it into the machine, and see if it all still works. I'd run some stress tests (there are utilities that can do this for you, or you can have a local repair guy do it), and see if the machine is having any issues.

The most common components that are damaged by a power surge are:

• Memory
• CPU (processor)
• Motherboard
• Hard Drives

Those are the most common to fail. If you use a new supply, and notice your machine does NOT turn on, chances are, one of those devices is burnt or damaged as well. It is suggested to test them in turn, to see where the issue lies.

yes!you need to supply also the 220v the control running in 220v,110v only for the motor/s

You would have damaged the power supply section but in many cases the front end contains a surge protector with a variator which will short and blow the fuse. So check fuse replace and check for short in the input circuit of the power supply, if the Switch mode is damaged then you need to replace the unit with a 220 volt type or if only the 110 type is available then use a step down transformer to down the mains to 110V with about 0.5Amps

It most likely has a 110V plug on the power supply; however, all you have to do is buy the appropriate 220v cable for the power supply for your country, and it should work fine on 220V.
External power supplies are designed to use either 110v or 220v -- all you have to do is change the cable or use an adapter and you're good to go.

Make sure the printer is plugged into a functioning wall outlet supplying the proper voltage (110V or 220V).
If you are using a surge protector, extension cable, or power strip, plug the printer directly into the wall outlet.
Press the power button to turn on the printer.
If the issue persists, unplug the printer and wait 15 minutes.
After 15 minutes, plug the printer back in and press the power button.
If the issue persists, try a different power cord (if available).

The power supply isn't a transformer, its a switching power supply. The power supply is different for different locations, but you should not plug a 110V only power supply into a 220v source or vice-versa. You should contact iRobot if you wish to obtain the correct power supply for another location or to determine if they have an autosensing model that can sense and adapt to either 110v or 220v. You can also use a step down transformer to convert from 220v to 110v. The charger should be using 20W or less, but it will be pulling the current in narrow surges from the peaks of the voltage wave (aka a high 3rd harmomic current) and you will need to use a 40W or larger transformer to avoid unexpectedly overheating the transformer core.

No lights is not good. Power supply issue fo sure. Check th epower supply cable to your laptop. Are you running it on battery, or from a wall socket. Are you using it via a safety surge board, make sure the se are all funtioning too. If still nothing, you may have to take it to a repair shop as power suply may be damaged. Also if system has 110v/220v switch on back make sure it is set to 110v, and try again. Good luck lilacgerry xxx
