Powerbook does not power up 4 beeps...

I've been going through these topics trying to figure out what is wrong with my powerbook, but haven't really found out much, in part due to the vast amount of posts and also because of my faltering internet (thank you Comcast). Anyway, last night my computer shut down and when I restarted made 4 tones and wouldn't. But then I tried again and it worked. But this morning it did the same thing, 4 beeps, and now won't start up at all.
Based on the other posts I have found that these four beeps mean my computer has "no good boot images in the boot ROM." Ok great. I have a general knowledge of macs, but apparently less than I thought because I have no idea what that means. Can anyone enlighten me in more colloquial terms? Is this a reasonable problem for me to fix myself? Or to have fixed by the Apple store tomorrow? Or is this the end of my powerbook's life?
Thanks guys.

That means that the instructions which tell the computer how to operate don't appear to contain the steps needed for it to reach the point where it can transfer control to Mac OS X or another installed OS. This issue probably can't be resolved by end users.

My Powerbook will not power up, but I can hear the fan running...

Please help!! My Powerbook will not power up, but I can hear the fan running when I press the power button to attempt to power it up. I just received a new power adapter because it wasn't working properly and it was doing this before and then it worked for a week and now it will not power up at all. It just starts the fan but nothing else turns on. When I plug the adapter, with the battery still connected, it will look as if it is charging but then the light on the plug turns from green to orange then off and doesn't power up at all. If I take the battery out and plug in the adapter, the light stays on but it does not power up except for the fan noise. Does anyone have any suggestions? I also followed the two articles listed online in regards to resetting the power setting and the command + alt + P + R as well. Nothing works. Thanks in advance.....

Same here. If I start up with the power adapter attached, it starts up fine. If I try to start up from battery only, the fan comes on, the sleep light comes on but nothing else happens. I tried letting it sit that way for about 15 minutes and nothing changed. I tried attaching the power cord while in this mode and nothing changed. I tried the PMU reset a couple of times but nothing helps.
This computer is just over 1 year old and I have not had any problems with the power cord (3rd party), the battery, or any problem like this before. It started after a proper shutdown last night and attempt to start without the power cord this afternoon.
Any answers to this yet? I think I'll call on this and report any success to this discussion.

MacBook Pro A1260 - does not power on

The MacBook Pro does not power on.
When I press the power button shortly, the sleep indicator light goes on and goes off again (with the macbook going off) within less than a second.
When I press and hold the power button, the sleep indicator light goes on, stays on for about 4 seconds, then begins flashing quickly (4..5 times per second?) for a second or two and then goes off (together with the macbook going off).
What does the blinking mean?
I tried with the battery only.
I tried with power chord only (battery removed).
I tried with battery and power chord connected.
Each time the same result.
The macbook used to have an original power supply, but that broke down. Now I use a nonane replacement, which worked well for some months.
What can I do to fix it?
EDITT:
The screen remains black all the time - the macbook does not beep. I can hear the DVD drive start up - also I believe that I can hear the CPU fan.

8800 does not power on but shows the charging symbol! HELP!

Hello everyone,
I have been searching for days now across the web for a solution to a very bugging situation. A'las i am close to giving up. someone please try and help. So here is the problem: I recently bought a 8800 rim (branded for cingular/AT&T but UNLOCKED) from ebay powerseller with 100% rep. it was advertised in MINt condition.
It arrived two days later and seemed in great physical condition.
So i plug in the charger and let it charge for more than 8 hours. I try turning it on but to no avail. During the charge the screen goes dimly on and shows a battery with an electric bolt going through (I assume that means charging..).
It initially seemed to me as a battery problem. So i took it to a local store and borrowed one of their batteries for 8800 and the phone started working fine also made a call with my temporary T-mobile sim inserted. (although their battery was also on low charge)---
So i come home and with a new OEM 8800 battery. plugged it in and charged for like 4 hours and the screen goes on with the charging symbol but does not power on.
I have repeatedly searched through the WWW and came across wide variety of dilemmas but none were any helpful. I also tried installing the latest OS...which also spectacularly failed [got an error that ...loading failed during the mult-load seesion...or something like that. I followed several very well written guides [advising that the manager and OS be installed on PC and etc.].
SO I MAKE A DESPERATE REQUEST FOR HELP FROM ANYONE OUT THERE WHO CAN HELP. WHAT'S THE DIAGNOSIS WITH THIS BB. IT WAS ABLE TO WORK WITH THE BORROWED BATTERY FROM A LOCAL STORE..EVEN MADE A CALL AND EVERYTHING...BUT WITH THE BATTERY THAT CAME WITH THE eBay PURCHASE AND THE THE BRAND NEW THAT I BOUGHT....IT DOES NOT POWER ON.
BESIDES HOW LONG SHOULD I BE CHARGING IF IT IS NEW OR IF THE PHONE HAS NOT BEEN IN USE FROM SOME TIME??
THANKS IN ADVANCE.
Please help ASAP.

How are you charging the BlackBerry? Do you have a wall charger or are you charging via USB cable from your PC? Its also possible that the charging circut in your BlackBerry is faulty. This would explain why a charged battery works while your uncharged battery is not.

Time to replace it: $49 2nd Gen shuffle at online Apple Store...

I have had my iMac for 55 days now and twice I had to power off/on and then It does not power up correctly. I verified my disk and found errors that could not be repaired. I erased the drive and restored system back to the previous day.

I have had my iMac for 55 days now and twice I had to power off/on and then It does not power up correctly. I verified my disk and found errors that could not be repaired (errors were associated with boot drive) I erased the drive and restored system back to the previous day. Has anyone else experienced this problem?

Since it's a new machine, contact Apple's Support and let them deal with it. Allen's already recommended an Apple repair station visit. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you might be eligible for an onsite repair since yours is a desktop machine (depends on where you're located). BTW, the AppleCare Protection Plan's the best warranty policy available for desktop machines. Get it if you don't have it before contacting Apple.

Screen/Computer does not Power Up when life the Display from being Closed

Sometimes (not always), when i come back to my MacBook Pro and open the display after it has been closed for a bit, the screen and computer does not power back up or anything. If you look at the screen there is a very FAINT image on the screen of whatever was open when the screen was closed, but you can't do anything, nothing is responsive, etc. I have to hold down the power button until it turns off, and then right before it turns off the screen will power up for one second and then shuts off. Any ideas?

I am having a similar issue when transitioning from my external display via the Mini Display to DVI adapter back to the internal LCD. The screen will go black, the machine will not sleep if I close the lid, and none of they key commands appear to work. The only response I can get is the caps lock key will turn off and on. When I restart the machine, I get no details on a Kernel Panic, or anything else, so wondering if it has something to do with the video drivers.

HT4061 HOW CAN I GET MY SERIAL NUMBER WHEN MY PHONE DOES NOT POWER ON

Not sure why you need the serial # if you phone is locked.
Plug it into iTunes, and you can get the serial #, and also unlock your phone.

Nomad Zen Xtra does not power

I have just recieved my Zen Xtra today. But when I power it on, per the manuals proper instruction, it does not power on. I have also tried to charge the battery with the mp3 player both on & off. When I had it on the "using AC outlet" icon would show. It does seem I need a new battery. But I fear something else, could the charging mechanism be dead? This player is a refurbished product by the way. It works on the AC outlet, I can transfer files to it, and I can successfully connect it to the USB port. the hard dri've sounds fine. It seems I need to buy a new battery right? Where else besides Creative.com can I buy one? Thanks.

First, read/try the advice here
Failing that, I would suggest buying a replacement battery. Check froogle.com (that link is set to the best deals) for a good price.

T61p 14.1" Does not power up

My 14.1" T61p Type: 8891-CTO laptop does not power up.
After my last successful use, it was sitting idle for 2-3 days with battery & AC adapter connected. When I turned it on nothing came up, no battery charging light or display. I do not have mini/advanced dock.
So far I've tried the followings:
1.) Removed Battery & switched on with AC adapter (with & without circuit breaker)
2.) Removed AC adapter & switched on with Battery
3.) Removed HDD, RAM, DVD Drive one at a time & again used step 1 & 2 with no luck.
I bought it new in Dec'07 & still under warranty. I have never used Lenovo support before but from what I've read, their on-phone support sucks.
a.) Have you faced similar problem or know the solution?
b.) Does Lenovo have any local repair center in NJ or NC where I can physically carry the machine & get it fixed?
c.) What will be the fastest/sure-shot way of getting it fixed?
Thank you!
Warm regards,
Hitesh

Ok! It's fixed! I disconnected AC, removed the battery. Then, I took out / reinserted the MEMORY CARDS. As soon as I plugged in the AC, VIOLA! Indicator lights were on. I replaced the battery. I powered up the pc -- battery showed only 2% juice. Moral of the story: if you leave the pc in hibernate (prolly sleep mode too) for an extended period without plugging in, the battery will lose juice and the pc memory will remain in the previous mode, unable to register when AC is available. Not ideal, but what I think that's what it is. OR - someone else suggested that the PC needed a longer time to recharge after wasting all the battery juice -- and that I should've been more patient. But, the PC had been on the AC for 2 hours and no indicator lights were on, which made seemed to indicate that the PC was unable to register that it was attached to the AC power. I needed to get some work done, so I was ready to try anything. When in doubt, take the mem cards out. And reset them.
Sayonara!

Ipod does not power up unless plugged in

My ipod touch does not power up unless plugged in or connected to the computer. It is fully charged and when I unplug from the power outlet or computer it will stay on for a minute and then turn off again. It only shows the apple icon when I try to turn it on unplugged and then turns back off.

Likey the battery is dead.
Try the following to rule out a software problem
- A reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory settings/new iPod.
If you still have the problem that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order

Power button lights up for a few seconds but does not power up

Hello
my computer froze up so i shut it down via the power button but now it does not power on when pressing the power button the button lights up but as soon I let go the light goes out and nothing happens not noise form the computer
anybody can help.

Hi, racb -
Try resetting the PMU - Article #HT1939 - Resetting CUDA/PMU
Also, it may be time to replace the internal battery. Those batteries have an expected life of about 4 to 5 years; leaving the machine disconnected from live power regularly or for an extended period can reduce that time a lot. You can get a replacement at places like RadioShack for about US$18, cheaper on-line.

[SOLVED (Arch is a great community)] Thinkpad x220 does not power off

My thinkpad x220 does not power off, it goes through the whole shutdown process as expected until reaching the last step where it displays "> POWER OFF" and just sits there until the battery is empty or I force the power off by using the power button.
I don't know what's wrong or where to start looking for clues.
The same happens when rebooting, it displays "> REBOOTING" and sits there.
Occasionally on reboot attempts I have additional messages from iwlwifi:
iwlwifi 0000:03:00.0: Queue 9 stuck for 10000 ms.
iwlwifi 0000:03:00.0: Current read_ptr 28 write_ptr 29
iwlwifi 0000:03:00.0: On demand firmware reload
iwlwifi 0000:03:00.0: Could not load the INST uCode section
iwlwifi 0000:03:00.0: Failed to start RT ucode: -110
iwlwifi 0000:03:00.0: Unable to initialize device
-edit-
Not sure if this could be related but my thinkpad has the particularity of having a renice x3 mSATA SSD that I installed myself.

This is what you're looking for : https://bugzilla.kernel.org/show_bug.cgi?id=33872
I've had this issue before, also on my X220. The solution was to remove the e1000e driver before shutdown. I've placed a command that does something like "rmmod e1000e" in a configuration file that runs it on shutdown, and it fixed the problem. I forget where this file is though... Hopefully someone else can fill the gap =]

Satellite Pro 440 CDT does not power up

Hi, I have an old 440 CDT which does not power up. Anyone any ideas???
AC is connected, power light is on, green. Battery is dead (as in buried). When I press the power button, the following happens:
- On light is green
- Num lock key (the one with the "A" on it) flashes 3 times: long-short-short
- HDD light flashes on 1 time, green
- CD light flashes on 1 time, orange
- Popping sound in the speakers
Then it turns off again, with the power light burning green constantly.
Nothing happens on the display (tried FN F5). I also switched CD/floppy, attached both, with or without battery, no help.
I am puzzled, please help!
thx, Eric

Hello Eric
Like you know, on this way it is not possible to give any precise diagnostic, just speculate what the problem can be. In my opinion it is definitely because of defective electronic on board but what exactly it is not easy to say. Try to contact someone who has experience with notebook repair procedure.

760GM-P23 FX does not power on

First build in a while. I just purchased a 760GM-P23 Fx motherboard. It does not power on.
I installed an AMD Phenom II X6 processor, and one 8GB DDR3 memory module. Plugged in the ATX 24-Pin power connector to JPWR1, and the ATX 4-pin connector to JPWR2.
Power supply does not turn on -- fan does not run.
Disconnected both power connections, shorted pins 13+14, confirmed the power supply works. Tried also with a spare power supply, neither works.
The motherboard is sitting on a non-conductive surface -- a painter's tarp on the workbench.
Is there something else I should try before returning to store for a replacement?
Thanks

Double check your connections to JFP1, are the case switches and LED(s) connected to the correct pins? Short pins 6-8 JFP1 with a small screwdriver or whatever as a test and see if PSU starts up.
