Can a laptop get a "fatal" electric shock through its USB slot?
I plugged an external CD drive into its USB slot. After I connected the CD drive to a (maybe too strong) power adapter (1500mA), the laptop went dark and could not be started anymore. Zero reaction! I suspect that the external CD drive or the power adapter via the USB has killed the power supply of the laptop. IS SUCH THAT TECHNICALLY POSSIBLE?
The power supply is more likely to have supplied the wrong voltage.
Coincidence.
Yes, but that would probably damage the external CD drive. But can this spread to the laptop via the USB interface?
Thank you. My laptop calms down again…
The power of 1500 mA does not matter, but the output voltage does. If this is higher than + 5V, then other components in the laptop can also die, depending on the structure of the motherboard.
Depending on whether galvanically separated logic converters etc. Are installed, the supply alone is done externally.
Well, I don't see that from the outside of ACER. Well, I have to send it in anyway.
Well, that's 9V
USB uses a voltage of 5 volts, if 9 volts come into the system, you grill a lot.
Unless the drive would explicitly allow a different voltage, but I don't know any run-of-the-mill types.
