    Default I'm Nervous re fix

    My Lenovo Thinkpad keeps losing audio then most times audio returns 1,2 or 3 days later. Not this time. As Covid closes business I have been given instructions to fix myself. I'm assuming the repetition is a "Typo".
    My ancient laptop an old HP I was planning to use as backup in absence but it now is not charging -says Charged at 5% -been plugged into mains. I did not think battery was that old and wonder if it is charging cable.

    Anyway i am a bit nervous re the Lenovo steps.

    i should appreciate comments. I assume "Working machine" means the 32GB USB stick.

    To Lenovo Customer By Service Email (Neil Fitzjames) (23/08/2021 08.24 AM)
    As at Monday morning New Zealand time audio has not corrected itself automatically as it often does.

    Under Synaptics Driver properties the same old error message
    “Device is not connected to this computer (Code 45)”

    This does seem like a permanent Hardware problem that keeps recurring.

    Lenovo suggestion

    Default Re: I'm Nervous re fix

    Another thing you can try is boot the laptop with a live Linux distro, Ubuntu or something similar...

    If the sound works on Linux then it's unlikely a hardware issue, but if the sound doesn't work (and drivers are installed) then it's possibly a hardware issue.

    It's not uncommon for a vendor to suggest a recovery like this but usually that is a last resort if "standard" OS/software/driver troubleshooting has not resolved the issue...

    Corsair Hydro H100x

    By "working machine" they mean a PC coneccted to the internet so you can download their recovery media and put it onto a USB stick. Your machine will probably do that ok. The USB stick needs to be at least 32GB it can be larger.

    Backup anything you want to keep before doing that, seems like it'll reset everything and you might lose your data and programs.
    It's not uncommon for some technical support and repair guys to go straight for the nuclear reinstall windows option, quickest and easiest for them.

    The Linux live distro is a good Idea to sort out if it's hardware or software without changing anything.
