I have a probleme since i got my Imac 27 Mid 2010. It just dont boot when a usb Drive is plugged in. I had i Firewire hard drive in the past and i had no problems to boot up on it. Turn the mac on, holding option key and bang ! BUT usb just dont work, it stay on gray screen and after a while (10 mins) it boot on my regular internal drive.Â
I tried several usb drives and it's always the same. It look's that im not the only one that have this problem.

I think the title pretty much explains it all. I'm wondering if there's any harm that would come from leaving the power adapter plugged in all the time, but without the MacBook connected some of the time. I'm a college student, and with the way I have my desk set up, I can't really take the power adapter with me everywhere I go. So yeah, I was wondering if there was any harm that would come from it.
View 4 Replies View RelatedI get this strange message every so often, sometimes more often than other times. It says:
USB port drawing too much power. The device that is plugged into it will be deactivated.
There are only two things plugged into the USB-The keyboard and mouse. When I get this message, the mouse freezes. If I jiggle the mouse cable where it is plugged into the USB, it comes back and everything is fine until this message comes up again.
The battery says it is at 99% charge but the computer shuts down when I unplug the power cord.

I have two usb hdds connected to a usb hub. I've never had any issue with it(the hub). After I installed the last update 10.7.3 everytime I restart my computer if I have the hub (with all my hdds and other devices) connected to my computer, the computer won't boot. It get up to the white screen (before the loading wheel). If I unplug the usb cable it starts booting inmediately.

Will this have done any damage? The macbook pro was not powered up, but I had the the mac ac adapter plugged into a power strip with the magsafe adapter connected to the laptop, since I keep it plugged into ac all the time at my desk. The power strip was on while the power outage happened. I had the 3 prong extender cord of the magsafe plugged into the power strip. The power outage was due to a problem with some power lines in my neighborhood, not from a surge of overuse of fuses in my home, so my whole block was without power for about 2 hours.I did notice the power strip has always had 2 lights on; one red, not protected, & one green, grounded. The outlets in my room are only 2 prong, so I have a 2 to 3 prong adapter plugged into the wall that the power strip plugs into. I know this is not the best, but my house is a 1950's era house, & I do not have the knowledge & have safety concerns about trying to convert my bedroom outlets to 3 prong. I hope this did not cause damage to my macbook pro. Is there anything I need to do before powering the mac on to use the next time? besides convert my 2 prong outlet to 3 prong? will there be any static charge? this outage happened on a very hot & dry day in my area.
View 7 Replies View RelatedThis probably seems a bit ridiculous, but after having my first power supply melt and short out on me I've been completely paranoid of this happening again. My first power supply was one of the older models from 2006. I then got it replaced by one of the newer smaller models. After about a half a year it started twisting around on the inside of the cable which got me worried. The apple store wouldn't replace it unless it was melted so I called Apple and got a new one.
I've had the newer one for about a year and the cable seems to be wrapping around itself on the inside again. There doesn't appear to be a place where it's melting or breaking. I take care to not wrap it too tightly. Using it as a desktop replacement I'd like to not have to worry about leaving it plugged in when I'm gone. I find it crazy that this is even an issue but after having the first one melt right in front of me I find it hard to trust. Are the newer power supplies any better?
So I just got hold of a few of these new battery chargers from Apple and I'm just wondering if these are meant to stay plugged in the wall, even after the green light goes off. Does the light going off mean that the batteries will no longer draw power from the power outlet and that it is safe to assume power will continue to be consumed? Or is it preferred that I plug and unplug the charger only when needed to avoid any, unnecessary, extra power consumption?

I have a G3 iBook I've put together from spares just as a project. Everything works fine and will connect to the internet over the ethernet cable.As soon as I plug an Airport card in it refuses to boot, it won't even try so it seems to be a hardware issue.Is it possibly a dodgy Airport card or something else?It's a 2001, 600Mhz, Dual USB, white 12" iBook.
View 2 Replies View RelatedI added 2 sticks of 512 to my power mac g5 1.6. I had ahard time getting the computer to see the new ram, but finally was able to kinda get it working after zapping the pram. However my computer only saw these 2 sticks as 256, odd. So i attempted to troubleshoot the problem. I tried just installing the new ram, but the computer wouldnt boot. I tried a few different combos with the other 4 sticks i had, but nothing. I put the old memory back in, and still nothing. The power led looks to blink once every five seconds or so. I tried pressing the pmu reset button, but still the same out come. I also tried taking out the battery, nothing.

This is bad and old, and full of lessons about backing up. Anyway, internal boot drive crashed a week ago, and internal optical drive is busted. New external LaCie dvd burner works fine, but all attempts to start up from Tiger, Leopard and Diskwarrior installation disks just end up back in OS10.3 on my external LaCie FW drive. I've tried many things: unplugged everything; switched external LaCie to USB (wouldn't boot), unplugged power from internal optical drive so Mac wouldn't look there first (somebody suggested that). Attempts to start up installers from mounted DVDs result in installer screen with restart button, which, when clicked on, results in... you guessed it... boot back to dreaded 10.3 system. Night owls and westcoasters, I am up for hours yet, pulling hair.

my old 2x2Ghz PM G5 (late2004) doesn't launch the boot sequence:
- when pushing power button, the blue led turn ON as long as I keep it pushed. If not pushed, it light off but yet the fan are running.
- no chime
- the fans turn on normally and the hard drive start a little to make noise once powered up.
- no video on display, the screen is black.
- the keyboard is not recognized anywhere I plug it. Â
- after a minute or two of non activity, the fans start to blow full speed (guess its a security measure for saving processor)Â
I ve done the reset of PMU several time (unplug the power cord then push the button at bottom of mother board)As i dont have access to keyboard, I can't start on Target mode to check if the HD is failing all.I ve removed all RAM extensions and left only one pair in slot 1 (J0), and changed the pair to avoid a faulty RAM.I only have a redlight on motherboard if I don t put back the glass panel.I ve check the voltage of the lithium battery, and yet its the original, the voltmeter says its 3,6V...Â
I use my MBP 15" (the new one), as my primary machine in my office. I sit by my best usually 10-12hrs a day working on it.
I am trying to figure out what is best to do, keep the AC plugged in or have it un-plugged and only plug it in when the battery is drained (or less then 50%)? I have tried different experiments, plugged in, not-plugged and time is about the same for life of the battery. The true question is, how is is best to do it for the health of the battery.
last night I was using my computer just chatting with people, then all of the sudden it shuts off. Now it won't boot past the apple grey loading screen, and the fans slowly rev up till they are full boar, and I have to shut it off for them to stop. Â I've reset the PRAM, the SMU/PMU, tried holding alt and selecting my drive to boot to. None of these did anything, and didn't help at all. Â
I've heard it's a processer or logic board failure, or a HD failure, or something else. I'm ready to buy a new computer, I'm actually kind of sick of this one, I just want to know if I can fix it or not. I will probably take it to the apple store just to make sure, but maybe I can get an answer on here to know how to fix it or just to know that it's dead.Â

Having trouble booting up my old G5. If I'm lucky, I can hold down the 'C' while pushing the power button and it may or may not boot after several tries. Using tiger 10.5 (?) Can't remember the exact version because it isn't booting up anymore. Last time it did there was no keyboard/mouse recognition. Is there any key combo to try other than the 'C'?

Had a power outage.My hopped up G4 tower with 2 - 200 GB EIDE drives on an EIDE PCI card. It crashed and one 200 GB EIDE drive didn't survive.(Yes it was on a UPS but the UPS ran dry and the G4 crashed before it could be gently shutdown) I removed the crashed drive and made sure the remain drive was jumpered as a single master drive. It wouldn't boot. All I got was the gray screen (no logo no paddle wheels, no start-up gong) I replaced the battery on the motherboard (commonly known as the PRAM battery)It wouldn't boot but I heard the start-up gong. I booted off the Leopard install DVD and ran Disk Utility repair disk and repair permissions. No problems were found. It wouldn't boot. Still gonged though. I installed Leopard onto an external firewire drive and connected it. Restarted holding down the option key to select a boot drive. Selected the Firewire drive. It wouldn't boot - gray screen only (and the gong). I installed Leopard onto the surviving drive and it appeared to install properly. It wouldn't boot (get used to this result). I erased the 200 GB drive and installed Leopard onto it. It wouldn't boot. I took my trusty PowerBook - booted it in target mode and then connected it to the G4 and booted off of it. Success! That worked. So I downloaded the Leopard Combo Updater and updated the Leopard on the 200 GB drive. Tried to boot off the 200 GB drive. It wouldn't boot - however now I have an Apple logo on the gray screen - still no paddle wheel though. At this point I was reseating PCI boards, EIDE cables, and all that stuff. Yes, yes, I reset PRAM a few times and so forth. It wouldn't boot. I pulled 2 SCSI drives out of another G4 tower and installed them and "option-started" the G4, selected a SCSI drive to boot from and it booted off an old version of Tiger. Once it booted, I could see the 200 GB EIDE drive and put files on it and everything! So, it's not like the drive is broken. I ran Disk Utility again just to be sure and it appears to be fine. When I select it as the start-up disk, it won't boot.Â

My back up 1.6 ghz G5 power mac is misbehaving. I moved the system to another room and when I went to boot up, the only response I got was the fans running at normal speed - and then they started to slowly creep up to a very high speed. No hard drive activity, no monitor activity. I swapped out the memory for the original factory mem - same problem - reset the switch... nothing.
