USB-c charging and no thunderbolt icon in notification try battery icon

I am using usb-c charging of my notebook and when I plug in the cable it shows the battery icon with a thunderbolt and if you hover over it it says plugged in.
When the system sleeps and I wake it up, the thunderbolt is gone but it still says 'plugged in' when hovering over it. But the battery is on and draining.
If I unplug and plug it back in , the thunder appears and charges, otherwise the battery is on and discharging.
What is going on?

Some (laptop) systems have a setting in BIOS / UEFI to allow charging even when asleep / powered off, though I think this might be disabled by default. But to be sure, you'll need to check your system's owner manual / user manual as to whether it has this feature or not, as well as whether the app can survive being put to sleep.

Who is the manufacturer?

vaio.

There are 5 different models listed with manuals at Sony's website:


Find the one you have and take a gander at the manuals to see if there is anything in there regarding the charging via the Tb connections.

I will check. I was just wondering if there was a way to tell if the usb-c cable (maybe needs both data and power?) or usb-c plug adaptor was the problem. Both are rated 100W.

I'm pretty sure it's not the cable, nor the port - if that setting is available on VAIOs but disabled by default, then it probably won't charge while in sleep mode.

But even if that setting is not available for VAIOs, the SONY app for detecting chargeable devices and displaying that charge icon may not be able to be restarted when the VAIO comes out of sleep mode.

One other thing - be sure to check and make sure your VAIO-specific software (and drivers) are up to date.

I have emailed manufacturer. Unfortunately the latest firmware driver and app with setting to usb-c charge when sleeping does not seem to work. Possibly a defect somewhere in the software or hardware. Only unplugging usb-c cable and plugging back works. Even the app says if does not work, unplug and re-plug. Great solution lol. I think perhaps to downgrade driver as its older computer and newer drivers for newer models may or may not have some changes that don't work past a certain version. If all else fails, I can use AC.
It could also be win 11 OS settings or other drivers, but probably not? Perhaps a safe mode trial is worth a shot. I don't recall BIOS having any setting related to this.

I suspected as much.

That is a consideration, too.

Depending upon when your model was developed, it could very well be Windows 11 being Windows 11 lol.

How is your power plan set up for the VAIO? Perhaps we can find one or more things that might be worth altering that might have a chance at making this work.
