    External Lenovo CD Reader-writer voltage question


    I am using 10.0.17763 build.

    Recently I was given an external Lenovo CD/DVD reader/writer that according to instructions printed on it requires 5v. input. I have a transformer with variable output which allows you to choose your required voltage output. Unfortunately there is no 5v setting; there is a 4.5v and a 6v. So my question is: Is 4.5v not good enough to make the unit work 100%, and could a 6v setting damage the CD/DVD unit by burning something inside? I know nothing about electricity.

    Incidentally, I have noticed that if I connect the unit to my laptop using a USB cable without any electrical input, it still shows on Windows Explorer and a CD in it can be ripped or copied without (seemingly) any problem. I don't know if this tit-bit is of any consequence.

    Thanks in advance for all help.

    External Lenovo CD Reader-writer voltage question

    Thanks Anibor, I was not aware of that. I just checked my system information and discovered that my 4 usb ports are all usb 3s. I have not tried writing with the Lenovo unit yet because for some reason I believed that that was the function that required the most power. Now that you tell me that the unit is actually getting its required 5V through the usb I shall try and write an audio CD and see what happens. For your info I shall report the outcome on this thread.

    Once again, thank you.
    My wishes to you for a happy and healthy 2020.

    The CD unit receives the necessary power (5 V) from the USB 3.0 port.
