Windows 10: Why is my disk active light blinking while in sleep mode?

My PC normally uses ~70 watts at idle. When I place it into sleep mode, it normally goes down to 0 watts. But sometimes, I come back to find that it is back to 125 watts by itself and the hard drive light is blinking. I turn on the monitor and there is no signal, so the OS is still in sleep mode. If I click a key, the logon screen will show up which is normal from sleep mode wakeup. So why is the PC operating with the hard drive running while in sleep mode. I have Brave and Edge open when I went into sleep mode. After I woke up the OS, task manager shows Brave, PfuSsMon.exe and avp.exe having

Sleep Mode with no light blinking

It is a brand new pc, a Toshiba P25W-C2300-4K. Among other things, the Windows sleep mode is working strangely, or inconsistently. It does go into sleep mode as set with power light blinking. However, if you leave it sleep for hours, the light stop blinking,
then you have to press the power button to wake it. (I already set it such that any key stroke should wake it up). As usual, the computer manual does not say anything about this (and many other things) and I have searched up and down to find an answer but
in vain. Why can't Microsoft make anything simple and consistent such as this. Older version of Windows did not have this problem of PC "playing dead" with no indication of being ON while in sleep mode.

 

Sleep Mode blinking led on N73

Is there any software/updates that will force the light to blink in a pattern or at least blinks faster to indicate any miss call or messages? I find it annoying having to get the phone out of sleep mode to see if there's any new message or miss call.

 

Multiple computers won't wake out of sleep mode/start in sleep mode

I am trying to reinstall Windows with a USB, following the steps, and I cannot get anything on the monitor. It is black and the lights are blinking like it is in sleep mode.
