Despite smoke and sparks, it seems to work...

Earlier today I was servicing my Powerbook (Ti, 1GHz), and while disconnecting the backup battery cable from the logic board I bumped the adjacent capacitor with a ring. There was a sprark, a wisp of smoke, and a funny smell (also some pain in my finger).
However, upon reassembling the powerbook it started up without a problem. I didn't leave it on for longer than it took to start up as I was eager to test it (I was installing a new display) and neglected to apply a new coat of thermal transfer material to the heat exchanger (because I don't have any and which I intend to get Friday)
Though it seems to be working, is there anything I should do/avoid doing to prevent any possible problems (besides replacing the logic board)?

Hi Peter,
Welcome to Apple Discussions.
If any damage has already occurred, I can think of nothing preventative to be done about it; you'll just have to wait and see how things work when repair is complete and you're able to put the PB through its paces. I can't imagine any further damage to other components due to using the PB after the mishap could be foreseen, nor is it likely.
Glad to hear you're taking care of the heat paste; I've wondered if some of the heat issues I've read about here after logic board replacements might be due to lack of heat paste or applying it improperly.

How do i use my imac 21.5" 2011 as a display for my macbook pro late 2011, through thunderbolt cable ? I have tried and it doesnt seem to work, neither does target disk mode.

How do i use my imac 21.5" 2011 as a display for my macbook pro late 2011, through thunderbolt cable ? I have tried and it doesnt seem to work, neither does target disk mode.
Could it be a borked cable ? I just bought it new from the store today, i have updated both imac and macbook pro to latest thunderbolt firmware and updates. Both 10.7.3.
MacBook Pro:

You are correct, here is what Apple Says:
http://support.apple.com/kb/TS3775
I was able to find these instructions, however they referr to 2009-2011 27" iMacs. I think it's the same, if it's not then contact Apple directly for instructions. If either of the machines is less than 90 days old or covered by AppleCare then call AppleCare tomorrow for help, they should be able to easily answer this for you. You will find the number in your manual or you can use the AppleCare Contact Info link.
Your iMac should automatically recognize the presence of a digital video signal at the Mini DisplayPort and enter Target Display Mode.
If your iMac does not automatically enter Target Display Mode, press command + F2 to manually enter Target Display Mode.

TS3212 I have now installed and uninstalled iTunes 10.7.0.21 about 5 times and still iTunes app will not launch. I have uninstalled my Norton AV and still nothing seems to work. Any suggestions would be appreciated.

I'm having problems installing iTunes on a Win 7 machine. The app will not launch correctly. It was working at one time, but now I have no idea why it would not work. I tried uninstalling some applications and still nothing. I did have to delete the Quicktime folders because it did not show up as being installed. Should I reinstall it since it doesnot look like iTunes reinstalled it?

Are you getting an error message when you try to launch iTunes? If so, what does it say? (Precise text, please.)

ITunes crashes when trying to sync photos, I have called Apple suport and I have erased and reloaded itunes, seemed to work better but then crashed again in the middle of sync photos saying ' IPAD cannot be synchronized. The file required cannot be found'

This seems to be a common problem...can anyone help?

Have you tried deleting the photo cache from your computer and then re-trying the photo sync ? The location of the cache, and how to delete it, is on this page http://support.apple.com/kb/TS1314

MacBookPro with 10.5.7 and CS2 Photoshop and CS2 InDesign- Seems to work ok??

Brand new 2.66 ghz with 10.5.7- read about restarting with command option and shift depressed for photoshop.. Everything appears to be normal.. but is this just a temporary situation?? Might I be able to avoid buying CS4? Anyone else having any success??
thanks
steve

CS2 is not native to the Intel Macs. It must run in Rosetta which is PowerPC emulation mode. this slows everything up. add to that CS2 is not supported in Leopard. If you can live with this fine. Most people with the new fast computers find using CS2 so slow they might as well be using there old computers. Add to that the incompatibilities with Leopard most people just don't want the hassle.
There will always be a few people who don't have a problem you might be one of these. YMMV.

I need to update my devices but can't because not enough storage. Purchased iCloud and still can't do updates and doesn't seem to work?

I can't do any updates cause I've no storage I bought storage and now I can't do update cause I don't have enough mb?i need an apple genius to sort me out! It's probably something simple and when I look up apples website about iCloud it says I need the latest ios6 but I can't update because it won't let me?!! Advice please?

iCloud doesn't increase the storage capacity on your phone. That is fixed when you purchase it. iCloud only allows you to sync data between devices, so they always have the same data.
If you want to increase the free space on your phone so you can update it, you'll have to sync some of your data off your device to make more room. One option is to import your photos and videos to your computer (http://support.apple.com/kb/HT4083) and delete them off your phone. You can sync some or all of them back later if you want. Another option is to sync some or all of your music off your phone. You can also sync this back later if you want.

I have hidden some columns which I now need to see again and can't seem to work out how

I hid some columns which I didn't need for a report and need to recover them but cannot locate them and they are vital - can you let me know how to find them again?

You don't. You go back to your iPhone and turn iMessage off. If you can't do that, then contact Apple Support for assistance.

Resizing of the navegation and search bars seems to work only with the default set of icons.

Unless the default set is restored, the double-headed arrows do not appear.

Do you happen to have Dial Assist on? This is in Settings>Phone. This is what helps the phone identify international numbers when dialing, based on location. See if turning that off/on makes a difference. Unless you are making a number of international calls, I believe this can be left off. See the User Guide http://manuals.info.apple.com/MANUALS/1000/MA1565/en_US/iphone_user_guide.pdf Page 49 has info regarding Dial Assist.

Safari on my iPhone 6 running 8.02 doesn't seem to work right. Some Java scripts don't show correctly and they do on other browsers I have downloaded. I tried almost everything and nothing seems to work to fix it. Please help.

Some websites like the one of my college uses JavaScripts and they seem to load correctly to a certain point but then not really. For example in one it would say select an option from the left menu. And I do it hut nothing happens. But when I go to the same website in another browser on my phone. The JavaScript works completely and allows me to see whatever I was clickig on that menu. I have seen that there are other websites being affected too. I tried clearing my cookies and data. even restarted my phone. And doesn't seem to work. I don't know how change the configuration any more to make it work like normal. At first I thought it was my school's website but it never got fixed. And now I realized is my safari browser! I wanna keep using it since I am really familiar with It. If someone knows how to fix this please let me know!
Thanks

You can reset the SMC and see if that helps. If it's a unibody or Retina, follow the method for "a battery you should not remove yourself."

FF 9.01 Stalls on Win7 64 bit laptop. Every time I load it, it just stalls and ignores all keystrokes. It's dead, baby! IE and Chrome seem to work OK but I'm a FireFox guy.

For the past week Firefox just stops whenever I load it. I can't go to any sites, can't trouble, etc. I have a newish Dell Laptop with Win7 64 bit OS. IE and Google Chrome seem to work on but I am reallt a Firefox fan. It is so odd that it would just STOP dead.

Try with only the 2 x 1 GB RAMs and see if it BSOD as well.

945pl NEO Mobo Smoked and Sparked.. Help?

Hi everyone,
Please bear with me as I"m not super technical and also a bit tired/stressed as well as new here.
Some months ago I decided to go to a dual cpu so I upgraded to a dual using the same board as before. It started up, everything was fine until I'd turn it off. Sometimes it'd start up and sometimes not so I'd just leave it running.
It was as if there was a short? Anyway I decided to see if it was the psu so I took it to best buy (LOL OH BOY) the woman there told me I was wrong in calling the cpu the cpu because the case was the cpu, the whole thing. (haha) I asked to have my psu tested (unfortunately it was her who tested it). Claimed it was bad, recommended a new one (DYNEX) (Specs below). I got it home, hooked it all up and it smoked and smelled bad. I turned it off and didn't touch it for months since it scared me, alot of money involved. No warranties existed for the others that I'm aware of.
I tried to figure it out today and took it all apart and reconnected everything thinking maybe I just had it hooked up somehow wrong and it smoked and sparked again! It's the silver grill top left of this board that did it.. resistor? I have no idea what it is. Looks like something you'd see on the back of a fridge, silver metal with ridges sticking up sorta like a grill. There are 3 black box looking things next to the cpu, they look a bit dull but no marks that I can see on the board (though I bet it's fried by now, gotta be!)
The bios has been cleared.
Previous psu (claimed bad by best buy "computer specialist") Athena 450w (trying to remember what you guys needed of the label) model no. PS-450w.
3.3v=28a 5v=42a 12v=20a (and 27a?)
max power 430w 115/230vac
New PSU: (made board smoke and spark) DYNEX ATX 500w model no. DX-PS500w(recommended by that assistant) 3.3v =35a, 5v =40a, 12v1=16a, 12v2=18a (voltage 115/230v)
My pc's specs:
Mainboard: MSI 945PL NEO version 1.0
CPU:Intel Pentium D Processor 915 2.80GHz 800MHz FSB, 2x2 MB L2 Cache
HDD:Seagate Barracuda 7200.10 320 Gigs
Video card: NVidia model P260 (which one? I can't see it on the card and can't remember)
NEC ND 2500A DVD r/rw & cd-r/rw
Sceptre monitor x9 version. Flatscreen. (doubt this matters)
ESM/DDR1g667 RAM (1 gig ddr/2 667.5300 16c/64x8/240pin
I'm already highly embarrassed about this.. but I'm hoping someone has had some ideas concerning things like this.. How do I see if anything got fried from the smoking/spark? I've read about some seeing if their chips were fried. Nothing is black or gray that I can see. The lights on the front would sorta flicker when I hit the power button. I dare not now though.
Any ideas anyone? Please...
Thank you for your time.. and please feel free to let me know if I've missed something. This is my first time posting about my pc work. Usually I figure it out. Usually.... *sigh*
Update:Checked cpu (no signs of burning) smelled the board, definitely the area I mentioned. When I hit power, it does occasionally spin the cpu fan but stops.. I hear a hum (electrical kind) but quickly shut it off.
I know how some feel about newbs but hey, this is the only way I'll learn.. to fix my own problems. Besides, you heard what I mentioned about the employee above. lol Some know less than I and they get paid to fix things (or break them).

Hi ya! I'm back and I think I'm running okay. Unfortunately the guy broke the plastic piece on my cpu's fan so I need to find another I suppose.. It's connected with 3 corners right now instead of 4. I knew it was bent but he went and broke it all off.. :( No longer usable on that corner. I couldnt' think of any substitute either.
It's an Asus board. NOT ascus like I"d said. I believe that is a medical term and I misused it. *blush*
I went to get the board and got also a gig of ddr. This board has a nice monitor for voltage, temp and fan speed! I LIKE! (no offense to MSI).
I'm new to the OS I have too so bear with me on the specs!
I was stuck in a delimma and I think I should mention it with this.. but not sure... It's part of what my problem was.. so I suppose it's okay. My problems come in packages, no individual sizes lol.
I had windows xp x64 bit and had too much trouble finding protection for the pc.. antivirus and firewall wasn't satisfactory to me. So, I went seeking an OS, anything xp or above aside from what I had. I found no regular installs, only upgrades. Can't upgrade x64 bit version of xp to home or pro... but vista I thought.. maybe vista. Only thing I could find in stores were vista upgrades and xp upgrades. I bought the vista upgrade (also a best buy suggestion by a geek squad member) to find it won't work!
I couldn't do the advisor as it's 32 bit. So I tried to run it anyhow. It wouldn't let me clean install NOR upgrade so I decided to try manually, my options were limited and it was a weekend. I deleted my hard partitions to make just one, I cleaned it all up and did a full install. Still couldn't register it :( but tech support walked me through it! They had me upgrade my clean install. That worked! Then I could register the windows vista premium! (it's nice but takes getting used to).
That's the update. I've been through hades lol. It was my board.. I'd fried it by leaving 4 mount screws someone had put in the case when I bought it. I wasn't sure why they were there and thought it was to stablize the mobo. *blush*
NOW I know, do NOT leave anything on the case that is metal behind the mobo.. NOTHING.. Unless the mount screws go into it, not the board up against it!! lol
I'm in working order with what vista rates as 3.2 pc rating. *shrug*
The sims 2 reguires 3.0 rating apparently.
The 2 gig of ram really pays off.
I hope to get another MSI board later.. It'd be especially nice if MSI offers a monitor like Asus does.
Thanks for the input everyone!!!!
The only thing that was bad was my mobo. Everything else, even after me trying to start it over and over, was fine. My cpu, my ram, my psu, hard drive, dvd burner.. Everything else was fine.. The heat sink was verified as the smoking and sparking part. I have kept the board wondering if a shorted board can be repaired as I really liked that board.
Sorry it was so long.. I'm notorious for long departures lol..
Have a wonderful, eventful and peaceful week NovJoe!! (as well as other assistants)
Parthina

Despite smoke and sparks, it seems to work...
