Replaced PRAM battery, now G$ Quicksilver won't power up
I replaced the pram battery. Now my G4 Quicksilver will not power up. The light is on in front of the computer, as well as on the front of the monitor. However, pressing, pressing and holding for many seconds does nothing. No sounds--nada.
I bought an iMac, and want to use the G4 in target mode to transfer files, and then set up a wireless network. I have no clue as to where to start, since the computer is dead with its lights on.

My iPhone prompted me to download the latest version of iOS7. I did, and now my phone won't power on. It just shows an iTunes icon on a black screen. When I connect my phone to iTunes on my laptop, the only option it gives me is to restore my phone's factory settings. But won't this erase all my photos, contacts, etc? Any suggestions?
It's in recovery mode. You don't have a choice. You have to restore the phone. Anything that was on it is already gone.
If you've been backing up/syncing on a regular basis, you won't lose anything except what's changed since the last backup. -
I Have just returned from a 2 week vacation and had left my iMac plugged in, I noticed we suffered a power cut during our absence from home and now the iMac won't power up, help !
What have you tried?
A safe boot?
A recovery boot?

Replace PRAM battery in in Intel core2 duo iMac?
I have just installed the iStat widget in my Intel Core2 Duo 2.16 Ghz iMac. I was a little surprised to see a battery level reading on it (of 45%). I wonder if it is measuring the remaining life of the PRAM battery. Remembering how badly my Powermac and my wife's G5 iMac behaved when their back-up batteries needed replacing, I want to avoid the same situation on my Intel iMac. However I can find nothing on Apple support for replacing the PRAM/back-up battery on an Intel iMac, so I am wondering if there is a replaceable battery or not. Anyone know?
Thanks

This section shows various information about your Mac’s battery. This section is only visible if you actually have a battery and won’t appear on desktops.
Percentage
The current battery charge as a percentage. This is also shown as a bar at the bottom of the section.
Time
Time left using the battery, time until charged, or “Charged” if the battery is fully charged.
Source
“AC” if the Mac is connected to mains power, or “Battery” if the battery is being used.
Status
This shows if the battery is charged, charging or draining.
Battery Health
This is a comparison between your current battery capacity and capacity of it when it was new. For example, if your battery lasted 5 hours when it was new, a figure of 50% suggests you should get 2.5 hours out of your battery now.
Cycles
The amount of battery “cycles” the battery has had. One cycle is defined as a complete discharge and charge of the battery, but partial discharge and charges also count. So, two half discharge and charges are the same as one complete discharge.

Need advice - should I replace PRAM battery even if I don't need to?
I'm getting ready to open up my iMac to replace the internal memory and DVD drive. While I'm inside, I was thinking I should go ahead and replace the battery. I keep my machine on 24/7. I have no idea how long a battery lasts. Its woking fine now. But since I'm opening up the machine and using thermal paste, and all, should I also replace the battery?
I assume pulling it out to replace it resets the PRAM. Not sure what effect that will have on my machine. What will be reset? Could it cause me any problems? What settings will I lose? I could always wait until the battery goes and then replace it. Is that a better idea? I don't know anything about PRAM, etc.
Thanks,
AlfredoAlfredo
Mac OS X: What's stored in PRAM? will answer your question.
Since you are going through the effort to replace the DVD drive, the loss of PRAM settings is the least of your worries. I presume that you have the necessary technical knowlege, tools and skills to perform this surgery, and as long as you have gone through the effort to open the case, I would also advise that you take this opportunity to replace the battery.

Apple just replaced my battery - but it still won't charge
Hi guys,
Just got my macbook (white, 13 inch, late 2007) back from the apple store - they did a couple of repairs on it and also replaced the battery which wasn't charging. The lady at the genius bar did a few tests on it and charged the machine with another battery and said it was 'definitely' an issue with the battery and not the logic board.
Brought it home today, plugged in the charger but the new battery won't charge. The charger light won't come on which makes me think it's the power adapter that needs replacing. The orange light came on briefly a while ago and the battery did start to charge but this didn't last. Just wondering if anyone thinks the same as me? I've already ordered a replacement charger so I hope this resolves the issue.
The adapter still powers the macbook for now but I don't know if that will continue. :sWhile you are waiting for the new charger, go ahead and reset you SMC:

What's easier? Replacing pram battery or hard drive and dvd drive?
I have a dead imac g4 flat panel with all my files and a dvd drive. I have a working imac same year, same processor but with only a cd drive.
First, I want my files.
Then, I wouldn't mind keeping one of them as a dvd player.
Would appreciate any suggestions!
(I don't actually know if it is the battery or power supply which is dead.)My experiences lately with my NEW (to me) 20" iMac G4.
1.25 GHZ PPC 1 GB RAM 160 GB HDD
Purchased on eBay in the orginal box for $349.00 delivered.
When the computer arrive it appeared to be in excellent shape. It turned on and operated without any problems. I really purchased as a project, and intended to restore to as NEW as possible. The iMac arrive with the usual specification for the model (born on date 3/2004). Specification were 1.25 GHZ PPC, 1GB RAM 512/slot.
So I purchased some parts to get started (like I said above everything worked).
1. OWC RAM 1GB/slot for a total of 2BG's ($55.98/Free shipping)
http://eshop.macsales.com/item/Other%20World%20Computing/2700DDRS1GBA/
http://eshop.macsales.com/item/Other%20World%20Computing/2700DDR1024/
2. OWC PRAM battery ($3.99/free shipping)
http://eshop.macsales.com/item/NewerTech/BAA36VPRAM/
3. OWC LG internal Optical Drive ($45.99/free shipping)
http://eshop.macsales.com/shop/optical-drives/superdrives/imac/g4
4. IOGEAR Bluetooth (ver 2.1) Adapter (USB 2.0 Micro) ($13.99/free shipping)
http://www.newegg.com/Product/Product.aspx?Item=N82E16833139019
5. Apple Wireless Magic Mouse (had a spare)
6. Apple USB Keyboard (newest) (had a spare)
Before installing the parts I cleaned out the dust and grim (nasty dirty), removed the Fan and cleaned (nasty dirty), I also removed the Thermal Grease and applied new Thermal Grease (used Artic Silver 5 Thermal Compound). I used a powerful vaccum and a air compressor (120 psi), and damp Q-Tips.
On the outter shell and back of monitor I used SoftScrub/Bleach lite scrub and then rinsed with a damp cotton rag (looks brand NEW). Was sure to remove ALL of the SoftScrub.
On the screen I used iKlear and a iKlear cleaning cloth, screen is in MINT condition.
Honestly the computer looks and operates much better than I had anticipated.
I really didn't need to install a new Optical drive in the 20" but it was a cheap upgrade. And so. I have a iMac G4 17" with the same spec's as the 20" iMac so I opted to install the 20" iMac's Optical drive in the 17" iMac. The 17" would only play CD'd and not DVD's.
After putting everything back together I installed Leopard 10.5.6, then upgraded to 10.5.8. I installed Quicktime 7.7 for Leopard and iTunes 10.6.3. Installed iLife09 (no iMovie), iWorks09, Superduper (latest), and Disk Warrior 4.4,
I chose not to upgrade the HDD simple because it is working fine and I don't have any critical information stored on it.
My final upgrade would be to install a new FAN but I'll wait on that for a while. Since the Fan operates fine it does have a very, very slight whine meaning the bearings are starting to wear a bit. Probably because of the dirt and grime that was on there from before.
I would like to buy a NEW Fan to install but right now the only option is to buy a Apple Fan (part# 622-6215). I wouldn't mind a non OEM Fan but the little fins on the side of the Fan's walls are a concern for proper air flow.

I will be opening up my iMac (G3 400 early 2001) soon to install a new hard drive. I realized this would be a good time to change the pram battery which is original, but still good.
If I do the replacement quickly enough will all the settings be saved? If not, what is involved to restore them? Is resetting the pram necessary? What, in general, should I know about doing this?
Also, since this will, at the same time, involve replacing the HD for upgrade- I will be cloning bootable external to new HD (with partition just below 128GB- how will the battery change complicate, if at all, this procedure? If settings are lost should I restore them when booted first from the external before cloning and partitioning? Thanks for any help on this.You are stressing too much about this. Just replace the battery. After you get everything reassembled you will want to reset the PRAM and then set the clock.
It has nothing to do with the hard drive. -
How to replace PRAM battery in Power Mac 9600?
Greetings. Need to replace the PRAM battery in a Power Mac 9600. Purchased a new battery, but can anyone tell me exactly how to remove the old one? Don't want to break the black plastic "cradle" it sits in. Thanks very much.
You need to remove the cover/retainer that snaps over the top of the battery holder. Using a very small screwdriver, insert its flat tip between the outside of the socket's positive metal contact and the battery retainer's end. Gently pry outward against the plastic retainer to unsnap it. You may need to do the same at the opposite end to completely pop it off. Once that's removed, you can actually grasp the battery by its sides and roll it up and out of the holder. Otherwise, insert the same small screwdriver under the lip on the outer rim of the battery's positive end, and pry/lift it out of the holder.

G4 upgrade now one monitor won't power on
ANY HELP WOULD BE APPRECIATED! I'VE BEEN UP ALL NIGHT!!
I put in 2GB of RAM today along with a super combo (DVD, CDRW) drive. I tested the machine with a single monitor at work, it was fine. When I got it home and hooked it up to my dual monitors, only one monitor turns on. The other one won't do anything. Now power to it at all. I tried plugging it directly into the wall, still nothing.
I switched the cords and everything and the same monitor (the one on left) turns on, but the one on the right doesn't. Can anyone help? When I detect displays, it shows I have two monitors, but I am only getting power to one. I also reset the PRAM, still did not power up my monitor.
Is there a workaround here or should I send it back? It's under warranty and everything. GoVideo Dual 19" monitors. Has anyone dealt with sending something back to Wal-Mart? Is it fast to get the replacement?

step 2: get a new 1/2 AA size 3.6 volt battery, install it, and reset the PRAM/PMU again. -
Help, my backscreen keeps flickering and I got told that resetting the pram (alt ctrl p and r) might fix it. But now it won't start up at all. It was working fine befor but now just goes on grey apple screen for 20 mins then the log on page comes up but it won't log in! I don't have the original install disk. I'm not sure what to do and I can't afford to take it to the apple store. What can I do?

Replaced HDD, now MacBook Pro won't power on.
Just bought a new HDD, Seagate Momentus 750Gb (link below). Installed it in my MacBook Pro, replacing the old 160Gb drive (also a Seagate Momentus, older version though) and when I tried to boot my laptop back up it won't even power on. I don't hear anything starting up, and the status light on the front doesn't turn on either. Putting the old drive back in and booting up it works perfectly fine, just like it did before swapping drives. The drive is supposed to be compatible with my laptop (MacBook Pro 3,1 Late 2007 15"). The drive is not partitioned or formatted, but this should not affect the laptop from powering up. I have no other computer to try the drive in to see if it is DOA but even if it were it again should not affect the laptop from powering up. Any advice on what could be causing the problem or something that I may have overlooked would be much appreciated.
Thanks, Chris

Your options, as I see them:
1. Contact Seagate tech/warranty support and see what they have to say.
2. Get an external enclosure to try the HD in.
3. Find another MBP to try the HD in. -
Quicksilver won't power down w/Leopard
After installing Leopard on my Quicksilver (w/GigaDesigns dual 1.8 processors), when I go to shut down or restart, the screen clears as if to power down, but the the spinning (whatever it's called) keeps spinning and I eventually have to hold the power button in to shut it down. It restarts okay. Even in safe boot, the same thing happens. Suggestions?
An archive and Install is not the same as an erase and install. The archive is great cause you get to keep all your settings and not re-install apps. but it can also bring problems to the new install that were present in the previous OS.
If you cruise the Leopard Usage forum you'll see suggested, time and again, if you are having issues with Leopard to do an erase and install. That means backing up and re-installing apps; basically starting over. I would Zero Out Data too to map out any bad blocks on the drive. Let us know if you need help with the Erase and Install. Beware, these procedures will totally wipe out everything on your drive.
Note; also make sure every app. you have on the Mac is able to run using 10.5 and get rid of every haxies you have. If you are using apps. from Versiontracker.com, go there and find the updates if they are available.
I would re-post in the forum I linked if you still have troubles after all this.

Camera flashes when charged battery is inserted. Won't power up.
Battery went dead while taking photos. I charged the battery. Upon inserting, the camera flashed (weird) but wouldn't power up. Then, the battery charger showed that the battery needed charging, so I did it again. In a few minutes it appeared to be ready, so I repeated the process with the same result. I thought maybe I ruined the battery, so I bought a new one.
Same result. I would think it's a software problem, but there's nothing I can do to get this **bleep** thing to light up!

MacBook won't start. PRAM battery?
So with a good power cable and full battery (used battery from another MacBook but didn't help) my MacBook wont power up. No fan, hard drive, white front light, or anything. I've had the computer for about 5 years, and it stopped working out of the blue. Should I replace my PRAM battery?
