Disable power LED blinks during Vista hybrid sleep?
I have a laptop that when sleeping is perfectly quiet, which is great. What isn't so great is trying to sleep with led lights that get brighter and brighter, then dim, then get brighter... all to let me know the computer is sleeping.
Well I also want to get some sleep.
How do I make my computer play dead (Dark and silent)? Eg: appear hibernated, (no lights, no moving HDD...) without hibernating, or shutting down my PC.
It would be even better if I could have the status lights work normally between the hours of 8 AM to 8 PM but I don't expect such an elaborate solution.
I do however want the answer to only affect the computer's software, not the hardware. No cutting cables or masking tape...
Laptop model may help here... – soandos – 2011-12-09T20:41:31.857

@soandos Are you sure there isn't a registry key or a setting that would apply to all computers? – wizlog – 2011-12-09T20:44:58.890
13@wizlog - I would be shocked if there were such a thing. The operating system doesn't control those lights period, let alone when the machine is in a low power state. – Shinrai – 2011-12-09T20:46:14.537
@Shinrai So the "caps lock" and the "num lock" lights aren't controlled by Windows? – wizlog – 2011-12-09T20:53:40.163
@wizlog - Not in the sense you mean, no, and those are still very different from the system power and activity LEDs. Think of the analogous situation on a desktop. – Shinrai – 2011-12-09T20:54:37.933
1@Shinrai What do you mean? Can you please cite something? – wizlog – 2011-12-09T20:56:13.067
@wizlog - AFAIK (and I may be slightly off here but I think the jist is right), the way the lights work is that you press the appropriate key, the system reacts, and sends a signal back to the keyboard to enable that light. The other lights are completely controlled at a firmware level by the motherboard, though. (This is why on a desktop chassis they're plugged directly onto headers on the motherboard.) – Shinrai – 2011-12-09T21:05:20.470
9The real key takeaway is that when your computer is asleep, the operating system isn't responding to anything anyway. So there's nothing in the operating system that'll be able to do this. – Shinrai – 2011-12-09T21:05:57.460
I have Fujitsu Siemens Amilo Pi model which have 3 leds, one blinking (while sleeping) and one turned on (when on AC). So when I went to bed I had one bright blinking led and one lighting at full. I had to put book before it so I could sleep. You'll have to do something similar. – Dalibor Filus – 2011-12-09T21:50:10.070
1Since you don't want a hardware solution, and Windows is asleep, I don't see much you can do. Maybe you can reprogram the BIOS? But perhaps you can train yourself to sleep anyway? I have been sleeping for a number of years in various rooms with one and sometimes two computers, and other things with blinking lights, and even though I am a light sleeper I usually manage to sleep anyway. (And just wait until you get small children. Blinking lights? Ha!) – Thomas Padron-McCarthy – 2011-12-10T09:44:37.853
Why not switch to using hibernate rather than sleep? The few extra seconds to wake up aren't a big deal IMO. – Steve314 – 2011-12-10T10:45:45.823
@Steve314 -- I've tried using hibernate on my Vaio. It does not go down or come up quickly, and often it will wake itself up after several hours anyway. – Daniel R Hicks – 2011-12-10T14:16:48.360
Brilliant question - my HP laptop has the brightest dang LEDs, and I often have this problem. – nhinkle – 2011-12-10T19:26:33.650
How is this exactly the same question? Does my question also refer to Windows Vista's Hybrid sleep? – wizlog – 2011-12-11T05:19:26.670
2@wizlog It's the same question because they're asking how to control the chassis LEDs from their OS while in a sleep state, just as you are. The answer is the same: you can't, because it's beyond the OS' control. Aside from the exact OS and exact choice of sleep state, how is your question different? – Ƭᴇcʜιᴇ007 – 2011-12-12T05:18:04.670
