A few days ago, I experienced a power surge (approx. 350 volts), which has affected a few appliances in my home and in some way, seems to have affected my laptop. I live in a country with 220-240 V power rather than the normal 110-120 of the United States. Here is the rundown of what happened.
After the power surge, I noticed that my laptop would no longer charge (although it worked normally off of battery. I assumed that my A/C adapter had been destroyed by the surge, so I got out my spare A/C adapter. Unfortunately, this did not seem to work either. On both A/C adapters, the light showing that it functions would turn off almost immediately after being plugged into the power source (but this did not happen before the surge). Does this indicate that these are being automatically turned off because of high voltage? They should not, since my power at home right now is at 200V and these say that they will function as high as 240V.
In addition, if I plug my laptop cord into a international adapter (designed to change 220V to 110V for use with U.S. electronics), then the computer charges. However, these adapters explicitly say that they should not be used with computers or other devices with electronic circuitry. They are designed for short term use and I do not want to fry them or my computer in the process.
Does anyone have any thoughts for me? Are these A/C adapters simply not functioning at the level of the electricity at my home? Did something happen to my laptop during this surge?
Any help is greatly appreciated.
