MacBook Pro Display Inverter Hum

Saturday, April 8th, 2006

I just wanted to post a note that will eventually be caught by the search engines for other people to find. I have a MacBook Pro 2.0 GHz with a W8607 serial number. The most noticable noise that I have encountered is the display inverter which appears to be caused by a less than solid connection to the case. At times, the hum from the inverter gets very loud, but I can immediately resolve the problem to almost unnoticable levels by firmly tapping on the display hinge on the right side of the unit. A switching inverter constantly oscillates, and it appears that the inverter oscillations are being amplified by the case similar to the manner of how a speaker voice coil transfers oscillations to the speaker cone. I’m tempted to open the laptop to see if I can tighten things up around the inverter or otherwise rectify the problem. If I do, I’ll be sure to post my results.

iPod and iBook

Monday, January 3rd, 2005

Those people in Asia are fast. For christmas, I ordered my wife a 20GB click wheel iPod. I was given the no-cost option to personalize my purchase by having two lines of text laser engraved on the back of the iPod. OK. What the hell. It adds 1-3 days of wait time to receive my order. This was Friday, 17-Dec-4, a week before Christmas. I really wanted to have the iPod here in time for the holiday, but the wife would understand if it was late. She even said so. I place the order and receive numerous emails from Apple about the status of the item. Apple, by the way, is very good at communicating the status of orders with their customers without nagging. Two emails show up on Friday. Then, when I least expected it, another email from Apple showed up on Saturday morning stating that the iPod had shipped. What?! Already? I look back through my order to make sure that I didn’t select the super-deluxe get-it-here-as-fast-as-humanly-possible shipping. Nope. It says free “parcel/ground” shipping. A quick look at the FedEx tracking number shows the iPod received by FedEx in Shanghai, China. Wow. Ground shipping from Shanghai. An interesting concept. And what is this? To be delivered by 6:00pm on Wednesday, 22-Dec-4. Needless to say, the iPod didn’t ship via ground. In fact, it is quite well traveled having started life in Shanghai then heading to Subic Bay and Paranaque in the Phillipines and onto Anchorage then Indianapolis and finally Cleveland. I’ve been to Indy. The best part of the whole thing is that it showed up before the big snow storm that halted pretty much the entire state on Thursday. Having ordered an iBook last Friday, 31-Dec-4, it appears that my experience will be even better this time.

I come in to work this morning after having off for the last 12 days and open my email to find that my iBook has shipped, complete with base package upgrades, yesterday. This time it started life in Taoyuan City, Taiwan. It’ll be here in a few days. That’s fast service.

Happy New Year, Baby, and iBook

Friday, December 31st, 2004

First of all.. Happy New Year! We’re enjoying what is likely to be our very last weekend alone for a very very very…very……..very.. (did I mention very?) …long time.

No new baby yet but any day now. I’ll be sure to post something when (s)he finally makes an appearance. I’m excited! Mom is doing well but very uncomfortable as is common with many late term mothers. We’re enjoying what is likely to be our last weekend alone for a very very very…very……..very.. (did I mention very?) …long time. :-)

I’ve started new year off well by ordering a brand new Apple iBook G4 today. I went for the 12.1″ display which isn’t very big but I’m interested in a decent laptop in a small form factor. The thing will weigh in at only 4.9 lbs but will include a PowerPC G4 1.25 GHz processor, 768 megs of ram, 60 gig hard drive, Combo drive (DVD-ROM/CD-RW), and Bluetooth and Airport Extreme (802.11b/g) wireless cards built in. It’ll be the last toy (for me) that I’ll buy for a while.
