Macbook and Powerbook Repair

Apple Inc (AAPL), stock hit an all time high today (it closed at 98.84), while my two Macs hit lows.

The Ethernet port on my Macbook (13″ Late 2006) failed. It seems that the connection to the logic board is loose. The nearest Apple Store is 72 miles away, and since I figured it’ll need a new logic board, I sent it off Apple Mail-In Repair in Tennessee. It’s still under warranty. They received it today and the repair status says, “On hold – Part on order (26-Apr-2007).” I guess that means they’ll fix it “real soon now.”

My other Mac notebook, a 4-year-old Powerbook G4 12″ (rev A) decided that it was going to have an intermittent connection with the DC power connector. I purchased AppleCare for this computer when I bought it, but that ran out about a year ago. So I had to fix it myself.

I highly recommend because they give step by step disassembly instructions with photos. It was a pain to take apart, in spite of’s excellent instructions, because the part I needed to fix required that everything else taken apart (except the display) first.
When I finally got everything apart, I could see the broken solder joint (circled in red) that was causing my intermittent power connection.

I guess it did “Test OK” when it was manufactured, but not now. A few seconds with a hot soldering iron and the connection was fine. Then it took me another hour to put it back together. As I said, a pain.


I bought a MacBook Core 2 Duo about a week ago. I bought it CTO (Configure To Order) with 2GB of RAM because I wanted to run some version of Windows. My last Apple laptop was a PowerBook G4 12″ rev. A, so the Macbook is a big jump in performance.

The only problem I’ve had was the DVD drive. DVDs and CDs wouldn’t mount on the desktop, though the drive showed up in the System Profiler. I was able to boot from the install DVD and ran the hardware tests with no problems. I reset the PRAM and then DVDs showed up on the desktop.

I installed Boot Camp and Windows Vista RC2 after it took me some time to figure out how to partition the 120GB HD into two Mac OS Extended partitions and one NTFS. I ended up using rEFlt for the boot menu and it works great. Vista runs with Aero on the Macbook’s Intel GMA 950 chipset. Performance is OK. The only problem is not being able write to the NTFS partition (reading works) when running OS X. Maybe someone will write a read-write file system similar to the NTFS for GNU/Linux.

I also installed Parallels (with a trial key) and Vista RC2. Even with 2GB RAM, system memory is paging out when Parallels is running so it seems that 3GB of system RAM would be ideal. Aero effects do not show up in Parallels with 2GB Macbook system RAM. Vista performance on Parallels seems to be about 75% of Vista on Boot Camp.

I used Michael Baltaks’ DoubleCommand and remapped the enter key to forward delete, so CTRL-ALT-DEL is now three keystrokes instead of four (fn-ctrl-option-delete).

I had no problems adding the MacBook, Boot Camp PC and Parallels PC to a Windows 2003 Server Active Directory. One thing I haven’t been able figure out is why a directory listing of a PC share is slower on the MacBook when I’m logged into the domain as opposed to logging onto the MacBook as a non-domain member.

Mac OS X 10.4.8 and SMB

I downloaded and installed the Mac OS X 10.4.8 Combo Update (PPC) for my Macintrash the day it came out.

I always look for improvements in SMB performance with OS X updates. My Macintrash is a member of a Windows domain and I have a mobile user profile stored locally. When I’m logged on to the Macintrash with my domain credentials, for some reason, getting a directory listing is very slow when I use SMB to connect to a network share. If I’m logged in as a local user, and connect to a SMB share using my domain credentials, the directory listing is instantaneous.

I use AppleScripts to log in to shares. Each script has an alias with a unique icon in my DragThing dock for each share. I just click on the alias in the dock and the share mounts:

tell application “Finder”
mount volume “smb://domain;username:password@computer/share”
end tell

I have used Group Logic’s ExtremeZ-IP, and it works great. I used Integrating Macs and Microsoft Active Directory at active directory page for help but there was no mention of this problem.
