New HomeHub 4 stuck on Green Power Light????

Just got this and it booted up fine then after about an hour it became stuck on a green power light.
Its lost all broadband ,wi-fi and lan connections and I can't even do a reset....any ideas
I've seen others with this problem but never saw a solution

Tried that a few times and it did nothing, the light remained on the whole time.
I have just managed to restart the hub by holding in the WPS button for 20+ secs and then did a software reset once my PC could reconnect.
So far its kept going and hopefully stays that way....the 1st hour or so showed a decent performance advantage over my old Homehub 3

3400c will not boot/ green power light remains on

Strange thing happened. We lost power while I was away and when I came back my 3400c was on (the green power light was lit) but it will not boot, shut down or power up. Will not respond to the power button or force quit keys. I tried removing the cd drive, the battery and unplugging but when I reconnect the power all that I get is the green light. No internal noise, won't boot. Also, I tried pressing the reset "button" in the back and the green light will flash but nothing else happens. It hasn't been my main computer for awhile and I no longer have it connected to the internet but it is nice for the kids to run their cd games on it. Anyone have any idea on how I can go about troubleshooting this laptop.

I've done a ton of tinkering with my 3400c, and currently am having fun installing Linux on it. Through my adventures with this thing, I've occasionally seen the stationary green light.
I'd recommend removing what's in the media bay, and any PCMCIA cards, unplugging all components and removing the battery.
Disconnect the unit from power and press the PMU reset button on the back, and hold it for several seconds.
Let the unit sit for about 10 minutes, just to be on the thorough side. Then reconnect the power cable (no battery/media bay necessary). What SHOULD happen is an immediate boot chime.
If the issue persists, you might try booting into open firmware:
Hold down Option + Apple + O + F, and press the power key on upper right of keyboard while holding these keys. Hold them down until you (hopefully) see a grayish-white screen.
If so, type these lines, return after each one:
init-nvram
set-defaults
reset-all
If all goes well, should reboot normally. If not, you may have a hardware issue on your hands. I'd try disassembling it and removing debris, looking for loose components or any point of failure, but if not you may require a new logic board. Luckily, either a 3400c or Kanga G3 board will work with these models if that's the case. (Only caviat is that the ram that originally came with some 3400c models will not work on the Kanga logic boards).

Compaq presario SR1504x green power light

hello
My compaq power light has started blinking every 2 seconds. The computer is running fine. Starts, loads up fine, other words it works good. Any idea way its doing that? I have not installed or changed anything,
thank you
This question was solved.

Hello dotdot65,
A blinking green light could mean it's getting close to time to replace your power supply.
However, let's try this troubleshooting step
1. Turn off the computer and unplug it
2. Hold down the power button for 10-15 seconds
3. Reconnect the power supply and boot up
This will kill all the power to the motherboard and completely discharge it, let me know if the light is solid green after that.

T60 will not power up (battery status led green, power status led green)

Ok so I have been researching this for a couple days now. Trying various things............
Including the famous 10 second power button press discharge.........
Symptoms:
1st Disclaimer - coffee was exploded all over the laptop but has been running for a month.
Symptoms:
It has been working post coffee spill (several weeks ago) as long as you left it running. I get cocky and turn it off then it wont come back on.
The laptop has exhibited the inability to power on since but I have been able to get it to turn on several times since.
green power light comes on with AC adapter only
plug battery in and the battery light goes green
press the power button - both lights go out
I replaced the keyboard, battery, tested for 20 Volts on the AC adapter, tested for 2-3 volts on the CMOS battery.
I tried testing for 20 volts on the motherboard where the power supply cable connects. I have most of the laptop broke down still.
I did get it running again last night as a result of me incorrectly using the multimeter and short circuiting the power supply connector .
It booted up and ran fine and I even tried turning it off and on again several times.
I thought it might be a heat issue. I turned it off and tried to turn it on this morning and it will not power up.
Same symptoms as before.
no battery, only power connected, green light comes on, plug in the battery, battery light goes green, try to turn it on and the lights go out.
It seems like it is fixable but I am not sure what to look for next.
Or should I be looking for another system board...........if so what should I replace it with
This is an IBM T60 Type 2613 15" screen.
Solved!

Welcome to the forum!
Your best bet would indeed be a new system board. Any single one from a non-widescreen T60/p will work.
I've got dozens of them available - send me a PM if you're interested.
Good luck.

BT Keyboard power light flashing???

Okay, so a nasty looking black spider crawled under the keys of my Bluetooth keyboard just now. Freaking out as I sometimes do (hey, I don't like spiders, what can I tell you?), I turned the keyboard upside down and beat it furiously to get the offending arachnid out from under my '4' key. After I'd done that (and squashed said arachnid), the G5 said it had lost the connection with the keyboard. I figured I might have knocked the batteries out of contact or something, so I took the opportunity to put a fresh set in. When I turned the power switch back on however, the green power light on the back comes on for about 5 seconds, then starts blinking. I put yet another set of fresh batteries in it, and it does the same thing. It won't connect to Bluetooth, and I'm having to revert to the crappy old G4 USB keyboard to do anything.
Anybody know why Bluetooth is blinking??
Thanks!
Butch

This may be fixed by now, but all you should have to do is just restart the computer with the keyboard off, then turn it on after the system as booted up. Also, the flashing light is actually a good thing: http://docs.info.apple.com/article.html?path=Bluetooth/1.0/en/blu28.html. It mean's your keyboard is discoverable.

New BT Vision+ box always has red power light

My father has just re-subscribed to BT Vision and received a new Black Vision box. Setup went through OK. Update received and installed fine at first boot. However, the Power light has never changed from being red, not the record light, but the power light.
The Box is working fine, you can watch, record pause, rewind, on demand everything. But the power light refuses to change colour, as I understand it should show either Blue, Purple or Red. Well we've never seen either of the first two. Any ideas? We tried turning it off completely overnight - no change.

Sounds like it's faulty, ring the THD 0800 1114567 and get another one sent.

Mac Mini (intel) don't start, power light is flashing green!!! Plz HELP!!!

I try POWER ON with Shift, Ctrl, D, X and nothing change.
The HDD is fine, because i withdrew and tested in other PC and boot fine.
If anyone has any ideas, please help.
Thanks...

If the power light flashes after power-up, it is very likely to be that the system is failing the power on self test, and the flashing is the way it is reporting the fault to you. If so, the system should also beep.
The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
+In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.+

HP 6940: carriage stuck at left side, resume and power lights flashing

I've used this printer under ubuntu/linux for about 2-1/2 years. Color printing has always been a challenge, I get about one usable page per 5 test pages. About a year ago, it stopped printing; hp-info (part of the hplip package) said the color cartridge was defective. I was able to get black&white printing by removing the color cartridge.
This week, I had to print some stuff in color. I pulled the color cartridge out of its ziplock, re-installed it, and ran a quick cleaning. A test print showed that wasn't enough, and I ran a full cleaning, after which I was able to print a good test page, and then one page of my job.
When I tried to print the second page, nothing happened, and the resume and power lights started flashing. I cycled power on the printer (I have to do this very frequently, even for black and white jobs), but it didn't fix the problem. I pushed resume, but no dice. I pulled the back cover to check for paper jams: nothing jammed. Replaced the back cover, pulled the paper from the tray: nothing jammed. Replaced the paper in the tray. Pushed resume again: it made noise, but didn't clear the problem.
I opened the lid, and the carriage was all the way to the left-hand side. Pushed resume: a small plate in the loading dock at the right-hand side moved forward and then back, but the carriage stayed at the left-hand side. Tried (gently) to move it to the right, but it's firmly in position.
hp-info now says:
"status-desc Paper or cartridge carriage jammed"
The color cartridge is an HP cartridge, and came with the printer. The paper is HP paper.
Any suggestions?

The Flashing Orange Power Light Of Doom! [HH3]

I've had no internet service for a week now, on Infinity 2 with HH3.
All lights on the white modem are green, the hub won't even start, just goes to a steady orange, then after about 15 seconds, a continuously flashing orange power light, and stays there. The other lights are dark. Power cycle doesn't work, holding down the reset button doesn't even reset it.
After lengthy "troubleshooting" on the phone with India, I received a replacement HH3 yesterday, plugged it all in and got all blue lights for all of 3 seconds and then - wham - reset to flashing orange light, which now stays there no matter what I do. The issue was escalated to "Tier 1 support" by India yesterday, but heard nothing.
No service problems reported in my area according to the BT website, but India seemed adamant that it was a network issue (after being adamant that it was a faulty hub earlier in the week...).
This is getting very frustrating now, anyone have any idea what could be causing this ??! I really just want an engineer to come out but India wouldn't arrange that.

It should be quite easy to prove by bypassing the hub and connecting the modem to the PC, then setting up a broadband PPPOE connection.
Here's some instructions provided by Rygg
try a direct connection to the modem. This will rule out your homehub and internal wiring as the fault.
1: Remove the homehub from the modem
2: Connect your pc/laptop into the modem using LAN1 port
3: Open network and sharing centre on windows and click set up a new connection or network
4: Connect to the Internet (the top option) then click make a new connection Broadband PPPoE
5: Username [email protected] and the password as anything you want
6: connect, if it cannot connect, just keep pressing try again if this happens and it will eventually connect.

Toshiba Satellite L505D wont go into sleep mode. Freezes before power light blinks yellow.

When i try to put my laptop into sleep mode by closing the lid, it freezes before it enters sleep mode. i get a black screen when i pick the lid back up, and the power light stays green, instead of blinking yellow like its supposed to. Last time i remember it working properly was around June 6th, i took my laptop to my buddy's place so we could watch the new Halo 4 trailers and i know it worked properly on both the car ride over and the car ride home. anyone have any ideas whats wrong?

Let's make some experiments.

New iMac is stuck on grey apple screen after restart from Migration Assistant

New iMac is stuck on grey apple screen after startup. It is a 3.4GHz Quad-core Intel Core i5 running OS 10.9.4. The problem occurred after a migration from my older 2009 iMac which is running Snow Leopard 10.6.6. When the restart occurred from Migration Assistant, the new computer will not boot up to the login screen. Disk utility did not solve problem. Followed instructions for a soft reinstall of Mavericks but that also did not solve problem. Any suggestions?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Deskjet 6943 No power light Resume light fully on

On power up of my deskjet 6943 the power light is off, only the resume light comes on (full on - not blinking) Nothing moves. I have checked the power supply. I tried inserting new cartridges and the printer looked like it was going to work, power light on, platen working and then it went back to resume light on and no movement. It would be totally dead if the resume light was not on.

design,
The green light is a sleep light, not a power light; the only time it should light (pulse on/off) is when the 'book is sleeping.

Battery isn't charging nor is power light

I'm in a pickle. My current 14" iBook battery is about dead. It only holds for about 30 minutes. Over the weekend it simply stopped charging more than 66% and the iBook power light isn't even catching that it's charging or not charging. Giving me a green light all the time.
I had a new battery arrive last Thursday, but the exterior plastic was cut wrong so it wouldn't fit into the battery slot. That was returned, but they have no idea when new 14" iBook G4 batteries will come in. Not even a clue.
Is it safe to keep the dying or dead battery in the iBook or should it be removed leaving the bottom exposed?
Mike

Some people have reported reviving the battery by starting up in Open Firmware and resetting the PRAM and NVRAM there.
Start up into Open Firmware by pressing and holding the Command-Option-O-F key combination during startup.
At the Open Firmware prompt, type: reset-nvram
Press Return.
When prompted for your password, enter it and press the Return key.
It responds OK.
At the Open Firmware prompt, type: reset-all
Press Return.
The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings. (This procedure has been reported to breathe life back into a dead battery.)
