Powerbook won't boot. Caps Lock Light and NumLock Light on. No other sounds

I'm posting a problem I'm having with my powerbook in the hope someone can give me advice as to what the problem could be. Or how i can fix it.
I have a PB G4 12" (1.33) running OS 10.4.11. All of sudden one day the laptop would not boot. I have tried the PMU reset, taking out the memory, plugging in an external firewire drive, etc but nothing works.
The laptop just won't boot, but I know power is being transmitted as the CapsLock light works, as does the NumLock (which is oddly activated by pressing F5).
Any suggestions/ideas on what the issue can be? Is it a dead mainboard/logic board? Or DCtoDC board?
Any suggestions/help would be greatly appreciated.

I found many others with the same issues.
Maybe we can read through their stories and find a solution???

Won't boot, Caps Lock light blinking, black screen, tried everything I could.

Hello!This is a problem that even made me scratch my head. It started two days ago: blinking light, black screen etc. (It was double-blinking, which mean't BIOS corruption). I looked around the HP forums for help and tried what I could find (keyboard combination, making a recovery disc out of a memory stick, which failed), but nothing worked. This sorta thing has happened before, but somehow it managed to revive itself, so naturally I ignored it, because I didn't expect what was to happen next, which is right now. Incase I can't get any help from here, I'm gonna buy an new motherboard, but what I am really expecting for is that the fix will not hurt my wallet and not buying a new motherboard. Hoping to get a response as soon as possible and not this to be overlooked. Perhaps this post will help other people in the future (Who knows?). Anyway, thank you for your attention.

Hi , Thank you all for visiting the HP Support Forums and Welcome. It is a great site for information and questions. I have looked into your issue about your HP Pavilion dv6-7000sy Notebook and startup issues. Here is a link to computer will not start. I would start at the top and work my way down. Mine was fixed with reseating the HDD. Others have had it fixed with just reseating the Memory. Here is a video that shows you how to remove and reseat the HDD and memory. Please note remove any and all USB devices. Disconnect all non-essential devices, as these could cause some issues. You could reset the BIOS with this document selecting the reloading the BIOS default settings. Which has helped others as it restores the default settings. If you should get the system started again, I would run the HP PC Hardware Diagnostics, It will tell you if something is failing. I hope something here helps any one of you fix the Notebook. Thanks.

Envy M6 Won't Boot, Caps Lock Blinks Twice

     My wife's laptop automatically installed some HP updates Thursday. After they installed, the laptop rebooted but only completed the shutdown portion. During the bootup portion, it never POSTs. It just sits there, blank screen, fan whirring, wireless radio light on (orange) and the caps lock light blinking twice every 4 or 5 seconds. I've also noticed that when I have a thumb drive in one of the USB ports, it powers up even when the laptop is off. And when I turn the laptop on, I see access flashes on thumb drive.
     I've tried disconnected the batteries, laptop and CMOS, with no luck. I've tried the hard reset procedure (WIN + B and then hold power for a second), with no luck. When I removed both sticks of RAM, it beeped properly.
     What options are available to me?

Hi @J1mM ,
Thank you for visiting the HP Support Forums and Welcome. I have read about your HP ENVY TouchSmart m6-k022dx Sleekbook and getting a blank or black screen on startup after updating. Try performing a hard reset.
When performing a hard reset please note remove any and all USB devices. Disconnect all non-essential devices.
You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook.
Here is a link to computer won't start for Windows 8.
If that does not help at the end of the document it shows you to do a hardware test.
Thanks.

PowerBook Won't Boot Past the Apple and Spinning Flower Screen...

I've been reading a lot of these forums, but still haven't figured out how to fix it on my laptop. So, I made my own topic.
Anyways. My dad gave me this laptop since he got a new one, so it's a hand-me-down which means I don't have this startup disk that I keep seeing talked about. I've tried Safe Boot, but when I do it with Command + V, it says all sorts of things that I just don't understand, and there is a lot of talk about the Apple Power Management? Such as:
com.apple.driver.AppleIntelCPUPowerManagement isn't a valid mach-o (magic is cefaedfe)
error mapping module file com.apple.driver.AppleIntelCPUPowerManagement
can't map com.apple.driver.AppleIntelCPUPowerManagement in preparation for loading
couldn't alloc class "AppleIntelCPUPowerManagement"
Etc, etc. And then the last lines that it ends with say:
BSD root: disk0s3, major 14, minor 2
[HCIController][configurePM] power parent ready after 1 tries
And it just stays there and doesn't boot up.
I honestly don't know what any of this means, or if it is even relevant to why my PowerBook won't boot past the Apple screen. If you have any information on how I could fix it, that'd be great. Also, if you have any questions that would help you figure it out, ask away and I will answer them.
Thanks a lot.

MixtapeChick:
Welcome to Apple Discussions. Congratulations on your "new" PowerBook. I suggest that you begin with this combination procedure:
• Shut down the computer.
• Locate the following keys: Command, Option, P, and R. You will need to hold these keys down simultaneously later.
• Turn on the computer.
• Press and hold the Command + Option + P + R keys immediately after the startup chime.
• Hold keys down until you hear the startup chime for the third time.
• Release the keys and immediately hold down Shift key to start up in Safe Mode.
• Log in and empty Trash.
• Restart normally and log in.
Let us know how it goes.

Laptop won't start quickly but power wifi and caps lock light keeps blinking

Hi, it has happened before too but rarely but nowadays it happens on daily purposes.
When I switch on my laptop after leaving it for 8-9 hrs, it won't start up but instead power, wifi and caps lock light keep blinking. I tried removing battery and pressing power button for few minutes but nothing happens. Then i left it like that with lights blinking and after 15 20 minutes it booted. I did same yesterday too. I left it like that it booted after 20 minutes..so My question is "why is this happening? Is it a motherboard issue or is it because of cold moisturous weather here and laptop takes time to get warm up?" Should I show it to HP Service center?

Hi @Nishant5788
Welcome to the HP Support Forums. I see that you are having a problem getting your notebook to boot up normally. As for what is causing the problem the blinking Caps Lock should tell us what is causing the problem as it should be blinking in a pattern. This HP document Computer Does Not Start and LEDs blink has a chart that will tell you what the blink codes mean.
This is most likely a hardware issue and you can give us a call regarding repair options. You can reach HP Total Care at 1-800-474-6836 in North America or start here if you live outside of North America.

My wireless keyboard is faulty. The CAPS lock light is permanently on and the other keys do not take any input. I have changed batteries, cleaned contacts etc. I cant even log on to the computer as its either caps locked or no input

Wireles Keyboard issue. CAPS lock light permanently on, when it goes off i cant input anything using keyboard

Begin by resetting the SMC and PRAM each at least 2x. If that won't work book an appointment at your local Apple Store or AASP. However before doing so, after you have done the resets (assuming they do not work) test another keyboard to determine if it's the keyboard or computer.

I cant use the X key on my imac wired keyboard, the key viewer shows the two commands keys pressed when i hit x and the caps lock light is always on....thank you

I cant use the X key on my imac wired keyboard, the key viewer shows the two commands keys pressed when i hit x and the caps lock light is always on....not really sure what happened, but i didnt do anything different from my daily stuff
just an update....when i hit the right command key it respond normal (cmd v cmd c...etc) but when i hit the left command key it shows the x and two commands pressed as well as it delete what i'm working on i.e like backspace but takes out everything at once
thank you

Hi Moe,
Sounds mostly likje a bad KB, do you have another to test with?
Or...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

I suddenly have two flashing lights on my keyboard by the caps lock key and over the end/pg up key.

I encountered a problem waking my laptop (Pavilion dv7-1270us) this morning. At first it would not wake up and had to do a hard reboot. Now I have two flashing lights on the keyboard -the caps lock light and the one over the end/pg up keys over the number pad. I have run several diagnostics and cannot find an answer as to what this is.
This question was solved.

Hi,
Try a Hard Reset as follows.
Shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery, plug in the AC Adapter and see if the notebook will start.
If the above fails to help, as your notebook is still under warranty, contact HP and arrange to have it repaired - you can check your warranty status Here.
If you live in the UK, contact HP starting Here.
If you are in another part of the world, start Here.

Hello kiranreddy,
Welcome to the HP Forums.
It appears that your Notebook is not starting, that you have a blank screen and flashing LED's. I will try to help you with this.
I would like you to start with this document: Computer Does Not Start and the LEDs Blink or the Computer Beeps. This will help to try to identify if the Notebook is providing an error code. If it is, it will also provide steps to attempt to resolve the issue.
Please let me know how you make out with this. If you require further assistance with this please provide the Model and Product numbers for your Notebook. (How Do I Find My Model Number or Product Number?)
Thank you for posting on the HP Forums.

I cannot log into my mac. I have determined that the caps lock is on no matter if the caps lock light is on or off. Anything I can do?

Hi lahiri,
Welcome to the Apple Support Communities!
I understand that the Caps Lock key on your MacBook Air is staying lit as if the Caps Lock is engaged and you cannot turn it off. One article I would suggest taking a look at in this situation is attached below. If the information does not help you solve your issue, please let me know more about the situation. Are the letters you type in all caps all the time or can you adjust between upper and lower case using the Caps Lock key and the light just stays on?

2009 Aluminum Keyboard caps lock light not functioning

Greetings:
I bought my wireless keyboard in February 2010 and it works but lately the caps lock light has not been coming on when I hit the caps lock key. I took it to a local Apple Specialist to try to figure out what is going on and it of course worked when he paired it to his machine.
I got it back home and re-paired it to my mini (2009 2.25 mhz intel) and it worked for the day... now it is not functioning again. I unpaired the keyboard and re-paired it again and the light functions again for the time being. But if it holds to pattern, tomorrow it will be non-functioning again.
I have the latest update for the keyboard installed and I am at Snow Leopard 10.6.3 on the system.
It appears that if the keyboard goes to sleep, this phenomenon happens. Any ideas?

I think that re-pairing the keyboard does essentially the same thing as restarting the machine would do with regards to resetting the keyboard. I did replace the batteries today just to see if that would help. -- so far, the light is working still and the keyboard has been asleep for a couple of hours since I replaced the batteries. They showed 81% when I replaced them this morning.
I would like to know if this is a common problem. The keyboard always works, just the caps lock light stops working which is annoying for me because I tend to hit it by accident and the light is a good way to see that I did, in fact, hit the key.
I am marking the question as answered, but hopefully someone has a real fix for it, or Apple has a new firmware update coming soon
