Blue light next to the PSC 2400 cartridge
I wonder because I can't find anywhere in the documentation.
I have a PSC 2400 (no network capabilities).
Next to the cartridge is a little blue light which is still active. You can see it on paper when it prints, and you can even see when opening the printer (for example, paper, stuck or when replacing the cartridges).
I wonder what 'blue' light is... Why is that?
It is inside the printer, next to the cartridge and moves with the cartridge. It is not an indicator of some sort.
Thank you!
It's an old printer, but that the light operates as a sensor. Function of the printer, it helps with the process of alignment and remote sensing possibly different types of media/paper.

MacBook (retina, 12 inch, early 2015) El Capitan 10.11.5 now ongoing enforcement.
Whenever I try to access the camera FaceTime (FaceTime, Photo Booth Apps) the green light next to the camera made a slow blink, and there is no picture.
The system report > camera > model ID: Apple camera VendorID_0x106B ProductID_0x1570
The numbers of the vendor and the product are correct?
The camera worked for 6 months passed and I used FaceTime several times without problem. Several users are affected.
None of the recent changes to the system.
Since the problem began, I have:
(1) installed Skype to see if one application other than an Apple app had a camera problem. Skype has no camera or.
(2) improved 10.10.4 to El Capitan Yosemite. Hoping that the upgrade would reload the application Face Time. No change in symptoms
(3) reinstalled the El Capitan using the OS X Internet recovery. I have not used the time Machine.
(Note for everyone, it was simple and painless and does not need to reinstall applications.) I want to reinstall MS OS was too simple)
(4) several other threads suggested to reset NVRAM and SMC memory, even if they do not seem to be associated with the prob. who - without success here tried either
Any advice to determine whether it is hardware or software? Still dig while you wait for a response.
Note: This problem is not resolved

Light, next to the stack of DVDs orange blink?
I have a compaq 5700F desktop computer and the little light next to the pile of DVDs on the front flashes from time to time... does that mean? o.0...
Hello
If you mean the LED above the hard drive battery that is to the left of the power LED indicator is for the hard disk activity. When the hard drive is accessible, it starts flashing and that access should be a long series of access then the light will be constant.

When I turn on my laptop, only the light next to the button Cap Loc flashes.
Model G61 - 408 CA
Windows 7 operating system.
In the last session before the problem occurred online, I noticed the operations were very slow. I checked the speed of the internet and it was good. I tried to reboot several times but nothing comes of usual noises from the machine to report that she has been commissioning. Only LED the arrow next to the button CapLoc and another light next to the Altec Lansing logo at the top right of the machine kept flashing. Nothing else happened after 15 minutes. Pushed the power button to close.
Tried again a few days later. Still nothing.
Hello
Yes, I would say you are right and it would certainly be my first not to replace what looks like a defective module.
Kind regards

My blue light flashes and I am disabled Bluetooth. Suggestions - it's driving me bananas

I first try a hard reset, just take out your battery for about 5 seconds and could again. Usually, which solves a lot of problems. If it is still on, it may be a software problem, but is not certain.

Thank you
Hello
This means that your mobile doesn t boot with AC/DC adapter and AC/DC adapter too?
Really strange what sHave you tried to remove the battery and the AC adapter? If you remove the two you should an hour and then reconnect the two. Maybe it will work.
If this isn't the case, it seems to be a hardware problem. You must contact an authorized service provider, you can give them a call to speak to a technician.

I have a friend who brought me their 11 2 weeks older HP flow because all day yesterday they tried to restart the laptop and may not have to start at all. I tried the famous hard reset by holding down the power button for 8-10 seconds of course which is suggested (I have it pressed for a good 40-50 seconds). I also now tried the power button and the mute for 40-50 seconds. No luck.
Unfortunately, the battery is good behaviour and because he is still under the manufacturer's warranty, I can't remove the back and turn off the battery in this way. (Can I ask what is the point to make the inaccessible battery that the mere fact that you earn more money by forcing people to return the product to HP to avoid the cancellation of the warranty? Apple does it too well, please do not follow their trend! I love HP, but this is going to force me to buy elsewhere!)
Can someone help me or point me in the right direction to help with this?
The light next to the power button is on and the light on the projection side, it is turned is on but the screen is black with no cursor. It has been unplugged for 3 hours in the hope, the battery is going to die and I can get somewhere with him but I'm not sure how close it is exactly to be dead.
She becomes very frustrated by that and I don't blame him. She's at the point where she will return it and switch sellers totally if it can't be fixed.
The battery is eventually died. I plugged in the charger and Windows restarted without problems. Research in the logs to see what happened, I noticed that it didn't have an update for Windows 10.
My guess is for some reason any it failed but the laptop supposed it was finished, restart it it basically says "wait, what am I I loading?" and froze.
Needless to say, I downloaded the update from Windows 10 and installed successfully. I restarted the laptop and now everything is fine!

Increase the contrast with the blue light grey and highlighted slight defect
Side bookmarks bar by default, the colors are a light blue background and a light gray highlighted bookmark name. It is briefly underlined a deep blue that returns almost immediately to a light gray. The two colors are very similar and the gray highlight is hard to find when you return to the page. Personas change the colors of everything except this. Y at - it an order of esoteric to increase their contrast? Here's the website if it works: http://imageshack.us/photo/my-images/818/camels.png/ . This color is also in safe mode. It is not due to an add-on.
You can create a style rule in Firefox to change the colors in this area. In this thread, I gave an example that changes the background color of the bookmarks bar, thus the highest point is more visible, as shown in the attachment.
