PowerPC :: 800Mhz EMac - 3 Beeps And Flashing Light On Power Up
Dec 12, 2010
My brother has a second gen, 800Mhz eMac (the one that could be overclocked to 1.33Ghz - the earlier PC133 ram model). Since about 1.5 mths ago, when he powers it on, sometimes it will not power on, and other times it will give three beeps (diagnostic pages say bad RAM) and a flashing power/sleep light in unison with the beeps. Did this vintage suffer bad caps? I recall that it was only the 1.25Ghz model that had bad caps, but I could be wrong.
When I push the power button on my eMac the light come on but it just blink and also make beeps. Can anyone tell me why I am having this prob.. I am new to Mac.
I have an eMac 800mhz and I'm having trouble discerning whether it's an "early" build which needs the original AP card or a later build. What exactly am I looking for in the system profiler to tip me off?
I recently acquired an eMac that was said to be working, but when I try to start it up, all I get is a beep or two, and nothing further. The machine is (I was told, I haven't been able to verify due to startup issues) OSX 10.4, 1.25 GHz. I put 256 mb RAM in, and I know that particular RAM stick works, b/c I used it successfully in my other 700 mhz eMac.
Shouldn't the machine start up without beeps once the RAM is in? I can't even get to the startup chime, so I can't do safe mode, FTM, or anything... When I push the power button, I hear the CRT firing up (but no picture displays), the fan comes on, and the white light on front comes on. After a few seconds, the machine beeps, and does nothing further... just that little white light mocking me.
have been repairing a 1.25 GHz eMac with the documented capacitor plague problem, and have managed to replace the capcitors within the logic board, however now when I attempt to boot up the eMac it gives 3 beeps and will not start, having looked up the condition I found it meant that it could detect no good RAM, so I purchased a 1GB DIMM from OWC and replaced the 2 x 512MB sticks in there previously, however the problem still persists and the machine won't boot.
My PPC G5 Mac Power Pro has been working fine, on one startup recently the screen didn't come on, the keyboard and mouse did not pass the startup test and the white light flashes three times. After a while the fans go into hovercraft mode! I've reseated the RAm and checked all other cards.
I have an old macbookpro which doesn't have a good battery. last night it shut off because I didn't have the power chord attached. now I can't power it up. the light on the power chord flashes (slowly) between red and green.
I installed several system updates on my 2007 iMac last night, running OS 10.7, and today I can only get a black screen with a flashing white power light when I try to start up. My computer will neither start up nor completely shut down, and my wired keyboard won't communicate either.
I just bought a new Logic Board for a 1.25Ghz eMac and I've put almost everything back together after installing it until I ran into a problem. The power button cable that runs from the power button on the casing into the logic board has no connector on the Logic Board itself, now I have an old logic board that whilst being broken has a connector on it but I really don't want to have to solder the connector on for fear of breaking the logic board.
I was attempting to replace the hard drive in my eMac, but for instructions I HAD to follow some darn take-apart guide that said pull out the connection for the power button cord from the logic board. I didn't know that it was SOLDERED in there, and now I can't complete putting my eMac back together without doing so.
Can this be fixed without having to send it to Apple? Does it HAVE to inolve soldering, or is there an alternative? Is there a way I can temporary have my eMac power on until I get the connector fixed?
I have an ibook G4 (2years old, a part of the battery swap program) that charges normally... for about twenty minutes. Then the light around the charger turns from it's normal "i'm charging" orange to nothing, the light goes out and the ibook switches to battery power. I've just inspected the power chord and there are no strains or tears, the plug at both ends are in good condition and the ibook power socket is fine too.
I've turned the ibook off for a period of time (two days) and reset the power manager... still no difference. The ibook looks and acts just like it should until about twenty minutes into the charge then the light turns off and it's like it's been disconnected. The chord is in correctly, i've even tried the apple extension chord = no joy. If i reconnect the power chord at the wall it's fine, starts charging again... and yes i've tried different sockets on different circuits in the house!
I searched forums etc. I have a 867 12" powerbook. The problem is that it will not turn on at all. I took the battery out and pressed a few key and it worked for a little while. Now when I plug it up to recharge the light goes green to red then off. I found a so called reset button on the apple site and lifted the keyboard and it is not in site.
Basically I'm having issues with my newly acquired Powerbook G4. When i bought it the battery was not working at all so have now installed a new replacememnnt battery which works fine but having some slight issues. So...
First time I charged it, it reached 100% but green light never came on to indicate full charge. When I run the PB off the battery it gets to 20% and it shuts down without any warning it's low on battery (trying to switch it on after this is impossible, it clearly has no life) After the above I connect the power lead and start up the computer, the battery indicator starts charging from 20% onwards. Something fishy definitely going on and I have no idea what it could be, I calibrated the battery but it has always cut off at 20% since first charge/discharge.
I have a G5 dual 1.8 power PC...Bought some ram put it in & booted up. Then a red light came on the logic board behind the power button. The machine wouldn't turn on....I called apple care & we rearranged the ram, now the red light is gone but my system still won't boot up. The white power light blinks every few seconds... the apple store told me sorry can't help because your machine is vintage. Even if my logic board is fried is there a place to buy one on the cheap?
I have been viewing the forums for the past few months and have finally joined MacRumors as I have purchased an ibook G3 (first mac). I love it to death, it is so portable and even runs like a champ considering it is almost 4 years old. The ibook has a 800MHZ G3 processor along with maxed out ram at 640MB. Anyway I am planing on buying an TV before school starts up again and would like to encode my dvds to h.264. I was wondering if my computer can handle this task. BTW I would need to buy a dvd drive for my computer along with an external HDD. My other option is to buy a friends Powermac G4 with dual 1GHZ processors(he is selling it at $250) it already has a dvd drive and two 200GB HDD so that will save me ~ 150. As I am new to macs and would like to know if the Powermac will significantly make a difference in encoding times or should I just stick with my ibook and save the $100?
I've got a G4 iBook here that is really really slow. It's running Mac OS 10.3.9, has an 800Mhz G4 CPU, and 1.12GB of ram (Built in 128mb + 1GB upgrade).
Activity monitor shows over 800mb of ram free, and about 16000/0 page ins/outs.
The CPU is also about 80% idle.
Something is fishy. There is only 6GB of free hard drive space.. but I don't see how that could cause this nightmarishly slow performance. It takes 5 minutes to open a folder sometimes! Could it be bad ram? Malfunctioning hard drive? Does it sound like a hardware issue or software issue?
I also noticed that there were a few folders in the hard drive such as "Previous Systems" "Rescued files" and "Damaged files." I already trashed "Damaged files" because it was just a bunch of random crap that no one would need and it was taking up space.
I have an EMac G4 that has a number of problems, It is a 1.25gz. Sometimes it will boot to a blue, blank screen, on holding down the alt key I see the boot drive and I can start up (10.4os) but will go to the blue screen again. When it does start up properly, which it does for no apparent reason, there are little dash shaped spots on the screen and a flashing horizontal flicker. I ran fsck and disk utility and installed a fresh version of 10.4 to no avail. I do not have the original disks so cannot run hardware test. The computer falls under the Apple emac screen repair but they will not accept it because it is out of the three year time limit, very frustrating and unfair.
I am working on a hardware hack with an iBook G4 800MHz where I can only power the iBook with the AC Adapter--NOT using the battery. When the compy is turned off and turned back on, I am getting this huge error message on the display that my time and date are wrong.
I gather there is no battery on the MB that sustains the internal clock--the compy uses the powerbook battery to keep the clock up to date?
Is there any way to set the system software to bypass or ignore the time and date? This computer is not connected to the internet, and time and date are irrelevant to my application.
Now, my poor little G4 was just standing there. After a lot of fumbling around, restores, it finally has regained life, running Tiger etc.
Now, I wanted to install Leopard, see for myself what I would prefer, and it would allow to tether wireless internet connection through my iPhone to the G4. But I need Leopard for that, Tiger is too old.
So, after Googling, I found out that if I put my Intel into Target Disk mode, I could use it as external DVD reader, seeing my G4's reader is dead as dead can be.
My wife's MacBook Pro has failed to start. Strangely the button to open the lid on front flashes.The computer recently had a new mother board put in. Feburary. Bit of a waste of money on and old mac. But there you go.Now we can't get it to turn on.Disk drive macs a sound but screen doesn't even turn grey.Can't seem to reset PRAM. Get no chimes at all.
I bought a new mpb , i7. a few weeks ago it turned off and it wouldnt turn back on when i connected it to the power source , the sleep light however kept flashing, and it madethis sound like if it was trying to boot. anyway,i left it charging for a bit and it started working on its own.
however, lately its been shutting down when it runs out of battery instead of hibernating (which is really frustrating). and just now its doing the flashing thing again, cept for a much longer time.. any idea how to resolve this/what might be wrong with it?
This morning my girlfriend booted up the MP and it froze when she tried to log on. A short time after freezing she was able to bring up the Dashboard but then the computer display went wild flashing like a strobe light. Ever heard of this?
