Windows 8 - Blinking Power Light
Oct 6, 2013
I've had Windows 8 sitting around since February, and got around to installing it yesterday. So far all is well, except for when I shut my computer off the power LED will keep flashing. At first I thought my computer was just in sleep mode, but after hitting a couple keys that was not the case. Is there a setting some where that would cause this. I know it's a minor issue but damn that LED is bright.
My systems specs
Intel Core 2 Quad Q9300
EVGA 123-YW-E175-A1 LGA 775 NVIDIA nForce 750i
Seagate Barracuda 7200.10 ST3750640AS 750GB
CORSAIR XMS2 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800
Yeah this machine is over five years old, working on getting a new one together soon.

I have a lenovo twist running windows 8.1. This computer will be running run fine but will freeze then come right back. It also will not wake up from a sleep at times and the only way to get it back on is to cut all power or hold down the power button until it shuts off. It just started not being able to do some of the windows updates.

I am using Windows 8.1 with all the latest updates.
I'm trying to get into safe mode, but when I do it is only a black screen with in each corner it says "Safe Mode" and the whole screen blinks every few seconds resetting the cursors position. The cursor and text are only visible when I am moving the mouse, otherwise it's all black. I can't do any button combinations like CTRL ALT DEL or anything.
Normal mode works fine, and I can't think of any viruses/malware that work allow you to work in normal... but not safe mode.
I have all my Windows 8 options disabled (Windows 8 mode, fast boot, secure boot) to see if it was those but to no avail.
Every time I try, I have to go into safe mode. It sticks, so I can't just reboot/reset and go back into normal mode. I have to go into the emergency cmd and do bcdedit to delete the safeboot value.
I usually clean my PC every so often, the same with OS re-installation but nothing is wrong with the normal mode and the OS still seems quite fast with the SSD.
I have never seen safe mode function, this is the first attempt at running it in safe mode. What could cause this? I can't get into safe mode but can get into normal mode...

I had a problem with my laptop in that the disk use went to 100% and then the screen started blinking and I couldn't click on anything. After a reinstall of the OS it worked the same as new for about an hour but now the disk use climbs to 100% even when a new tab is opened and it stays at the max for a short time. The laptop becomes unresponsive during this time also.

The caps lock light on my HP Pavilion G6-2356sa is flashing. The button still puts the letters in capitals, so it still works, just continually flashing. It's just stopped flashing actually.
Anyway, I've had a Google and all the results I've found say it has a black screen at the same time.

I just bought a Dell Inspiron laptop 17i17RM-2419sLV almost a month ago. Today the computer has started making a soft clicking noise that goes in sync with the flashing hard drive light. Is my hard drive bad already? I'm in grad school and can't afford for this to suddenly crash on me again. I actually bought the same make/model right before this and the hard drive crashed three weeks after I bought it. It was replaced for me and now here I with a almost constantly blinking light and accompanying clicking sound.

I have a wireless keyboard with no light that tells you when caps lock is on. I have found where I can customize my task bar to show the "HP LED Indicator" on the task bar. When you click on that, it shows you whether caps lock, num lock and scroll lock are turned on. But it disappears after about 5 seconds. I want something that turns on and stays on when I hit caps lock (usually accidentally, because this new keyboard has really low profile keys compared with my old one and I'm constantly hitting the wrong keys!!!!!). I don't want to be clicking something to see the status, I just want to see at a glance!
HP told me it's not possible to have that, but thought I'd check here too, on the Windows side of things...

I found that f.lux is really useful to your eye when you look pc all day.
However, I found that the light setting doesn't gradually change according to time.
For example, at noon the setting is at the highest peak. So there is different light setting across the day time.
It would be good for night if there is automatic setting for light gradually set to the lowest at midnight.
When this happen, the word and picture look totally different and the nothing come out from the blue colour. I might as well go to sleep and continue work tomorrow.
Is there a way to set a few setting and when the time come, f.lux change the light setting? It may not be fully gradually change but at less there is different in the light setting than have it all same all day.

I just noticed that when I go to the Power Options that the options are missing. It says the Power Plan is missing or unavailable or something such. One answer said to do a refresh or reset of Windows 8. Isn't that a bit drastic? Is there no way to do it by tweaks. I did that refresh once and lost more than I thought I was supposed to.

One day I go to shutdown/hibernate/sleep button and a pop up says "no power options available". I can still preform these options but I have to go through signing out first then picking. How do I change this? Oh, and no, I didn't add or upgrade, etc. anything lately.

I realized something interesting what happen using Windows 8 and 8.1, compare to Windows 7: a quite huge difference in power consumption!
For some special reason I was need ti install Windows 7 on my computer at home. I done that on an new HDD with 320GB, running solo for the installation by removing the power cables form the other HDD's, a total of 8 SATA3 HDD's. That was done 2 days ago and I firstly I installed only those Apps I need to use on Windows 7, no any gimmiks, whistles or bells! On Windows 8 I use Gadgets and the CPU Gadget show at middle 20%-25% while doing normal work.
I also have 3 different power circuit's at my home office, to each an Ampere Meter connected. On the circuit with my computer, which is connected to an 1.2KW UPS is also the Modem/Router 4 Port, LAN Switch 8 Port and and Debian Linux Server running. 2. Power Circuit has an Survailance Server and an Mail Server running and 3. circuit is for the normal other electric use like lights, power plugs etc.
Now on my computer's circuit the Amp Meter is 0-10A and with Windows 8 and 8.1 and the other devices, as pointed above, the consumption is about 2.6A-2.7A, depend on the work done on the computer. There is only 1 printer connected via the same power circuit, an Brother QL570 Thermal Label printer which is 99.8% of the time off line!
Now the interesting: running Windows 7 on the exact same computer with all HDD's running, as Windows 8, the power consumption is between 2.2A and max 2.4A! So, I installed more apps, mainly now the same a s running in 8/8.1 and also the gadgets. The CPU usage is mainly between 2-6% and may goes up to 15% by heavier work but reach 20%!
Both, the CPU usage and the power consumption is a quite huge difference using the exact same hardware, only difference is the OS Windows 8/8.1 vs Windows 7! In this, Windows 7 wins clearly!

My computer won't power off completely, SOMETIMES, i'm going nuts here.
Here are my system specs:
ASUS Forumla IV latest BIOS
ASUS GTX 690
2x4 2333 GB RAM
ANTEC 1200W PSU
1 SSD & 4 HDD
Creative ZXR SB
using latest drivers for all the above
sometimes the PC power off completely when i shutdown, sometimes not, the screen would go black but the power won't get turned off, the fans are still spinning and no BSOD...I have to either hard reset or hold the power button to turn it off.
I tried resetting CMOS, turning on and off the Fast boot feature in power options
With or without overclocking
Is there anyway to diagnose or investigate what is causing the PC not to power off completely?

I recently upgraded to Windows 8 (64-bit) and noticed I don't have power options available. I own an HP Pavilion DV7, usually when I leave the laptop to do something over night, I go into "Choose what closing the lid does" and I get the error saying my power plan info is not available. Whenever I try to create a powerplan it tells me the same thing, but when I hit next, it tells me it can't find the file specified. I have no power options at the moment. I tried resetting to defaults using cmd, rebooted, and the only power option I had (Razer Gamebooster) was gone, and had nothing after.

I installed clean Windows 8. I checked the event viewer to see if everything is OK. But it has 4 critical error and they were all Kernel Power Error. I noticed these Kernel Power Errors are caused by when I restart my PC. Example is when I installed Photoshop, I restarted and I checked the Event Viewer Log. There was an event Kernel error created.
but here is where it gets complicated. When I boot to desktop after restarting my PC, it doesn't say my computer suffered from a serious error. I have to check it manually by going to the Event Viewer Logs. If I don't check the Event Viewer Log, I won't know.
There has also been times where my PC won't boot to Windows 8. I goes past BIOS and Windows boot screen, but it hangs there. It simply crashes.
I don't overclock my PC. My PC temps are always low old IDLE and always within the max temp under full load.I have installed and updated ALL drivers and BIOS. I thought this might be driver issue but I realized this happened when I installed it clean and booted up for the first time.
This does not happen in Windows 7. Only in Windows 8.
I ran Prime95 for 12 hours -- no error
I ran Intel Burn Test for 9 hours -- no error
I ran Memtest for 12 hours -- no error
My PC specs:
CPU: AMD FX 8350 4GHZ
GPU: AMD Radeon HD 6870
RAM: 8GB Corsair Dual Channel
Motherboard: ASUS M5A97 R2.0
PSU: XFX 450W
Samsung 830 128GB SSD
500GB Western Digital HDD

I'm troubleshooting a Windows 8.1 HTPC (ASrock Vision 3D 252B) that sometimes starts up on his own.
Unexpected power on seem to be periodical, but checking scheduler, registry and BIOS, there's no scheduled power on.
It's connected to a SmartTV via HDMI, but unexpected power on happen also when SmartTV is off, so I think this is not a cause.
This computer is often powered on via WoL but, if there's no stange packets coming, i think this is not a cause, too.
I've just been disabling RTC Wake Up in BIOS, I have no idea what this feature is.

Lately just after I updated my Windows 8.1 all of the sudden my PC started shutting down for no reason and I had to restart it. It often occurs during the morning hours, but it also occurs during the evening hours, too. It's a Kernel Power error with Event ID 41, Version 3, Level 1, Task 63.
Here's the zip file and text document attachments I made which contains more information about what's going on with my PC.

I installed windows 8 on a desktop computer that had windows 7 before. Screensaver was working perfectly on windows 7. Since windows 8, the screensaver won't start, the display won't turn off after 15 minutes like I set it up in power options. Just to test, I removed all USB devices that could prevent the screensaver to start. I closed all the programs running in the taskbar, including those hidden. The screensaver won't start even if I set it to one minute.
Pressing the preview screensaver button works. But letting it go by itself doesn't.

I build out tons of machines of all makes and models for demo scenarios. One of the things that is the same on all devices is our custom power settings.
Is there a way to copy the power settings and apply them to any new laptop we build out?
Example:
Laptop 1: Power settings are set to never go to sleep, not require passwords on wake up, brightness set to max, disable adaptive brightness.
I am hoping to be able to run a batch file or something to accomplish this on every machine I build out.

I'm running Windows 8 Pro 64 bit on a Dell Precision 490 desktop. I upgraded from XP so it was basically a clean install.
I have my power button configured to put the system to sleep and it will do that ONCE after I turn it on. After that, pushing the power button does nothing until the next reboot or power cycle. Going to Charms -> Settings -> Power -> Sleep always works.
This obviously isn't a critical problem, but it's really annoying because I'm in the habit of hitting the power button and usually it just doesn't work.
Things I've tried:
- searching Google - can't find the needle in the haystack
- searching this forum - nothing that matches
- checking the Event Log - nothing interesting or suspicious
- apply all Microsoft updates - no change
- disable my Comodo Internet Security - no change
- change power options and then change them back - no change
- checked if I could stop and restart the power service - nope

Installed 8.1 about a week ago and I'm fairly happy with it so far (after removing charms, going straight to desktop etc) however I have a few minor problems.
Firstly my windows keyboard shortcut key is not working (Logitech G15)
Secondly in power options there are no plans that I can change, if for example I try to create a power plan I get the message "Your power plan information is not available". Tried sfc etc but no problems are detected.
Finally it just seems slower in some respects vs win 7 x64 ultimate, especially booting up. SSDs are all trimmed and aligned and all drivers are installed.

I recently reinstalled Windows 8 completely because I bought an SSD for in my laptop. I exported my power plans I used before the reset (when Windows was still on the HDD) and imported them again after the reset. In every power plan, Windows should go to sleep mode when closing the laptop lid, but that's not what's happening. Instead, Windows shuts down entirely, but the power light on my laptop indicates it's in sleep mode (flashing slowly). I also tried the built-in power plans (after just adjusting the appropriate setting), but the same happens. When i change the setting to do nothing (instead of going to sleep mode), it acts like it should: it does nothing.
