PowerPC :: G4 1.5Ghz Won't Boot Up

Oct 20, 2010

My PowerBook G4 1.5Ghz won't boot up. It happened about a year ago when I first got my new MBP so I just let it sit. But I'd like to give it to a friend if I can get it to work. I've tried resetting the PMU by holding shift+control+option+power... waiting 5 seconds and powering on, but nothing happens. The battery appears to be functioning correctly. When the cable is in it lights up like normal and the battery indicators light up and are in full charge. I've taken the ram out and put it back in. Any other clues what I could try before bringing it in to Apple?

PowerPC :: 17inch G4 1.5ghz - Brightness Stuck

Jan 3, 2008

For as long as I've owned my powerbook G4 1.5ghz 17-inch, the brightness has been stuck at a single setting. Both keyboard and menu changes function, and show that I've changed the brightness, but the brightness doesn't actually change. It even remembers what level I place it on, but obviously it doesn't matter since the brightness of the LCD doesn't actually change. I've done all the software updates and repaired my disk and permissions, and I've even tried resetting the PMU and PRAM(?) in the past, but to no avail. Now I'm wanting to sell the machine and have to replace the battery (since the display being bright has killed the battery over the years) and wanted to get this sorted as well.

Jun 15, 2008

Our old powermac died recently (G5 2.5ghz x2), the cost to repair was quoted at 850$, which is roughly the same price as a new Mac-Mini 2.0ghz. Just wondering how the performance of new mini compares to the 4 year old powermac? A new powermac is out of the question right now.

PowerPC :: Put 500gb Hard Drive In G4 1.5ghz?

Nov 7, 2008

I've been looking to upgrade the RAM and the hard drive in my powerbook g4 so I can prolong this little baby's life. I don't see the point in throwing something out that is still working. However, after a little scouting around online, I can only find 250gb drives advertised for Powerbook G4. Is this the case? Are there no 500gb drives that I could install too? Is there a specific type of drive I need?

PowerPC :: IBook G4 Won't Boot Past Apple Screen & No CD Boot

Jun 11, 2007

I have an iBook G4 1.07 GHz 30 gb 256 RAM with Panther. It was working fine until my HD got close to being full. Now I can't get it to boot past the Apple screen. It will either freeze there, or move on to the blue screen and freeze before the progress bar enters. I want to re-install Panther but I can't get any CD to boot during startup by holding "C", including the Panther OS CD, the Hardware Test CD, or the Tech Tool CD. I am able to boot to single user mode, where I type fsck -fy, and I recieve no errors with the hardware. I had this issue beore and my HD had to be replaced by Apple.

PowerPC :: Powerbook G4 Can't Boot To OS, But Clone Of HD Will Boot On Another Mac?

Oct 17, 2010

Got a Powerbook G4 with a "messed up" HD. Couldn't fix it, so got a firewire drive and ran a bunch of utilities from my newer intel iMac. Cloned the Powerbook's drive to a USB hard drive, did all repairs on the USB drive, formatted the Powerbook, cloned the USB drive BACK to the Powerbook, but it just gives me the flashing question mark when I try to boot.

What is REALLY weird is I can boot my iMac FROM THE CLONE ON THE USB DRIVE and it works fine.In Drive Genius the Powerbook drive (in TDM) shows as a single drive, but if I go to "Repartition" then it shows 3 smaller partitions on the drive; I believe they're called "Apple Free Space" or something like that (can't check right now, I'm running Repair on it AGAIN at the moment).

I feel like I'm missing something simple, like the machine just doesn't see one thing that tells it "Oh, yeah! There's an operating system on this drive!" I have tried partitioning from Drive Genius and Disk Utility. Have done clones back and forth with Drive Genius, Disk Utility, and Carbon Copy Cloner. Same results each time.

MacBook Pro :: Tell If It Supports 802.11n 5GHz?

Mar 1, 2012

As I wait for my Apple Extreme Base Station, I was wondering if it would make sense to create two different SSID networks. One Mixed b/g for 2.4GHz devices and another one solely for 5GHz. I know my ATV2 supports 802.11n in 5GHz. As I go down my list of devices in my house, I can't tell if my MacBook Pros support the 5GHz. Both MacBook Pros are Mid 2010 models. 

The reason for creating two different networks is that the AEBS downgrades your network based on the lowest device (i.e. b/g would be forced on a n device if such device connects to your network).

Applications :: Slow Flash Performance On 1.5GHz G4

Mar 12, 2008

I have had this issue for a while. No matter what I try, Flash movies are SLOW on my 1.5GHz PowerBook G4. I have 1.5GB of RAM, Leopard, and the latest Flash (Flash 9). Every video and game that I run in Flash is choppy unless I set the quality to "low". This occurs in Safari, Camino, and the standalone Flash Player application itself.

Hardware :: 5GHz Wireless LAN Transfer Speeds

Jun 19, 2010

Got a question for all you people experienced with wireless LAN transfers over a 5GHz 802.11n network. I just got myself a new AirPort Extreme and a 2TB hard drive. I'm planning on using this 2TB hard drive as a media server, but only for one stationary MacBook that I have hooked up in the living room. Here's my problem: If I plug the hard drive directly into the AirPort Extreme and transfer something from my iMac in my bedroom, the speeds are fantastic. I definitely see the 5GHz speed bump, and can transfer a 4GB file in just a few minutes. However, since the MacBook isn't that powerful, streaming a movie over WiFi seems to skip the playback a bit.

I would love to have the server plugged into the MacBook to avoid this skipping. I've tried playing a movie off a USB drive and it plays perfectly fine. However, when I transfer a movie from my iMac to the hard drive hooked up to the MacBook, the transfer speed is much, much slower (what would normally take a few minutes takes about 15). Why is it doing this? Is this normal, or should the transfer speed be theoretically the same as if the drive were plugged into the AirPort? I double checked that this MacBook is in fact connected to the 5GHz network (although it's at 270mbps instead of 300, but I don't think that should make that big of a difference).

MacBook Pro :: Manual Wifi Band Selection Between 2.4ghz And 5ghz

Feb 21, 2012

At my work place we have a lot of repeaters and some are on 5ghz and some on 2.4ghz, On my pc I can manage the driver settings to only run on 5ghz and the result is a much faster connection with better perfomance than my macbook air.

I have a macBook pro, running Yosemite, and cannot connect to 5GHz on my dual band bt home hub.  Keeps saying 'invalid password' even though it is correct.  I have given the 2GHz and 5GHz separate names and passwords and can now connect to 2GHz without dropping al the time, but am frustrated re 5GHZ.  Even when stood next to the router it will not connect or recognise password.

IMac :: Connecting Via 5Ghz Dual Band Between 27" And Linksys WRT400N Router?

Mar 11, 2010

I installed a WRT400N router via my PC several months back and used an adapter to utilize the Dual Band, Wireless N network. The product worked very well on my PC.

I recently bought a 27" iMac. It easily connected to the 2.4 Ghz Wireless N network. Performance and reliability are both good. However, I cannot see the 5Ghz network listed as an available network. Video streaming is not as good without the 5Ghz network.

Supposedly the 27" iMac (with built in wireless N) can achieve the Dual Band connectivity with Airport Extreme...but I do not want to spend money to replace a perfectly good router.

MacBook Air :: 2012 11" Slow On 5Ghz Airport Extreme Wifi Network?

Jun 29, 2012

I'm encountering an issue with a new Macbook Air and would grateful for any insights. I have an Airport Extreme (latest model, 5th gen, A1408) based network (all updates applied). I have a new 2012 MacBook Air (11") that I noticed was suffering from VERY slow wifi speeds. After looking into it, I realized that if I used the configuration utility to separately name the 5GHz network and connect to wifi on the 2.4 Ghz network, the speed radically improved. 

To illustrate, using speedtest.net, I saw download speeds of 35-38 Mb/s using the 2.4 Ghz network. This drops to 2-3 Mb/s when using the 5 Ghz network. The Macbook Air is showing an RSSI value of -56 when connected via 5 GHz and -51 when connected via 2.4 Ghz. 

Other deivces in the home have normal connection speeds on the 5 GHz network, as does a previous generation, 2011 MacBook Air.A friend's also new, 2012  11" MacBook Air exhibits the same symptoms, so the issue is not specific to my unit.

MacBook Air, Mac OS X (10.7.4)

PowerPC :: G4 Won't Completely Boot Up

Aug 28, 2006

I opened up Garageband, went into preferences to configure the audio for my peripheral audio device, and the computer and curser locked up, so I had to shut it down by pressing the power button for 4 seconds. I restarted the G4 and it would only boot up to a blue screen with the pointer curser, but would not finish loading anything on the desktop, no icons, no menu, nothing. I tried restarting repeatedly this way, but got the same result each time.
