Apple :: MBA CPU Cores Maxing Out
Mar 18, 2010
I do half an hour of normal browsing (no youtube or flash videos) like check my bank account, visit few forums, check email etc. and my MBA's CPU cores max out while the temp stats at 65-68C, I regularly monitor it with iStat. To remedy this problem, I put it to sleep for a minute or two and the air is ready to use for next half an hour.
In the past it had two problems, once when it's fan stopped spinning i.e. stayed at 0rpm and second time when it's lcd developed white spots in the middle of the screen. Apple fixed both under warranty.

I am strongly considering taking my laptop onboard to try and kill off a few hours especially as i have a good 100gb worth of films & series on it, but i want to try and squeeze every last drop out of the battery!
I will obviously be turning the brightness right down and turning off the backlit keyboard, aswell as wifi etc, but is there a way to drop the cpu speed to 15-20%, or whatever the laptop needs to run a film?
I wont need the full 17" screen, is there any way to turn off 3/4 of it so that i am only using a portion of it? if not is there any colour to use as the background that wont draw as much power, as im guessing fullscreen will draw more power.

I got a refurb Studio XPS 1640 with the below config.
-- Intel Core 2 Duo P8600 (3MB cache/2.4GHz/1066Mhz FSB) Windows Vista Home Premium.
-- 500 GB SATA Hard Drive (5400 RPM)
-- 4 GB DDR3 SDRAM 1066MHz (2 DIMMs)
-- 512MB ATI Mobility RADEON HD 3670
I have the below questions.
1) My CPU gets maxed out even if i have a couple of IE8 windows open. Is it normal or do i need to check something?
2) Also if i play any mkv files the movie is not smooth and is this an issue with processor?

Does the ZM-85: 2300 MHz work to? It says S1 sockel.

I noticed it was running really really hot, almost painful to hold your fingers against the rear fan vent. So I ran SpeedFan and sure enough the temps were whacked out:
1st core at reasonable temps (30ish)
2nd core from 65 - 90!
I tried following the disassembly guide for the DV2xxxx series here to take a look at the heatsink contact and fan but I got stuck at the logic board. (One of the disconnected WLAN antenna cables is impossible to fish out from the chasis, and after removing all connections, the logic board refused to budge fully)
So I just went nuts with compressed air on the exposed parts of the fan/heatsink, but that only helped a bit, temps on that core were still at a constant 65+ but the other core was at 30-35 and all other components were at okay temps...

I think the dell tech who was supposed to replace the heatsink also disabled 2 of my cores on my corei7 quad. On cpuz it is only showing up as 2 and same with on device manage

After applying the latest BIOS patch (76CN38WW) I've noticed a degradation in performance.Â
Â
Looking at task manager I see cpu speed fixed a 0.77 GHz and looking at resource monitor I notice only CPU 0 with any load the other 3 cores appear ideal (disabled?)
Â
Power plan is set to performance and is on main power.

Does anyone have the wired full size apple keyboard w/ the numeric pad?
I got it a couple days ago and it definitely takes some getting used to. But that phase is over now and I love this keyboard. The build quality is amazing and typing feels just like my MBP keyboard.

Conventional wisdom holds that one of FAT 32's classical limitations is a 4 Gigabyte files size limit. I've done a few searches on the net, and I find this rule repeated ad-infinitem, without contradiction.
I recently purchased a 320 GB Iomega Prestige external drive that I plan to use interchangeably with my Mac and PC systems. To do this, I re-formatted the disk to a single 320 GB partition with FAT 32 file system (The drive comes formatted NTFS).
Yeah, I know there are work-arounds that would permit me to format it NTFS, and use it read-write on my Mac, and there are probably a few solutions that would permit me to format it Mac OS Extended, and use it my PC. I prefer not to use any "workarounds".
Here's my question.... I had occasion to copy a few files to the drive from my MacBook to the drive, namely my Virtual Machine files, that I don't want to use Time Machine for. I had no problem doing so. The two files exceed 4 Gigabytes handily, with one of them being over 30 Gigabytes! Oops, this can't be done, right?
I ask, how is this possible? I thought I had a 4 Gigabyte limit with FAT 32. Does the fact that I formatted the drive with my Mac give me some sort of advantage that Microsoft's formatting using the same file system does not?
I have read that the reason the FAT 32 files sytem can't store files over 4 Gigabytes, is the insufficient lack of storage within the allocation table for the requisite number of pointers required for a file over 4 Gig in size.

I'm going to pick up a bigger HDD pretty soon for my rev A Unibody MBP. Would I be able to use the old 250 GB 5400 drive in the PS3? Seems like a worthwhile upgrade. I'm guess since they are aboth SATA it should work, right?

I currently own a Sony Vaio FW21M (16.4") and while it's an amazing laptop, it just feels too big to carry Also, is the MBP still small enough to carry around too?

Does the Apple MBP accept any type of 1066 MHz SO-DIMM RAM or is it special and has to be bought from Apple?

I am going to buy a mac in the near future and am currently conducted the research stage of my purchase.
I have been to a shop to see the MB and the MBP in real and am very very impressed with them.
I am going to be using my new computer for some medium gaming and i'm wondering which will give me more "bang for my buck"
So, what FPS can i expect on the following games: Unreal Tournament 3, WoW, COD:WaW, battlefield Series and L4D. On med- high settings using the Macbook and the Macbook Pro
And also which would you recommend? Any macbook user that wishes they upgraded to Macbook Pro?

I know that I have stated earlier that I wasn't considering the MBP 17 because the lack of portability, and that I already got a 24" Full HD screen.
But the thing is; I might be able to get the MBP 17 for the same price as the highend MBP 15, because of all the hassle etc that occurred.
I feel like, I don't really need the extra screen estate, I already think the 15" is barely portable, but the 17" got a great battery etc.
When it comes to what I'm going to use the computer for; mainly light stuff the coming time, but after that I'm going to start using final cut pro a lot and I know the 15" screen isn't enough for the ui of the program and the 17 is enough.

I would really like to upgrade my MBP to 8 GB of Ram as I use lots of VMWares in my job. I read that you can do 6 GB but I also saw some people trying 8GB of RAM on even older MBPs.
I read this with interest:
[url]
I'm sure you have also seen the article about the MBP only doing 6GB and not 8GB.
Has anybody here tried 8GB? With the 17" supporting 8GB, boy I wish they would allow it on older MBPs.
I'm hoping with Snow Leopard that 8GB becomes an option.

I am planning to buy base MBP sometime in next two weeks and then upgrade it to larger HDD by myself. I am wondering if the HDD that comes out of MBP can be used in my dying Dell Inspiron 640m (bought in 2007 and has 120 GB drive which has started to show signs of crashing anytime now).

I need to pick up a new notebook soon and I'm having a hard time deciding between the MB and the MBP. This will be my main computer and I do a good amount of traveling. Accordingly, I really want the portability of the MB, but I also really want the superior LCD of the MBP. Are there any other major differences I'm missing that might sway me? I'll be using this mainly for office applications and web surfing, but I'll also be doing occasional work in Adobe CS4 (I understand this would benefit from the MBP's dedicated graphics card).

I'm currently looking at options like the Balmuda Floater (kind of describes what it... oops, heh heh heh) but these still need a degree of space to site. They also all vent downards in a nominally usable config, which I'm not convinced is the smartest idea.
I'm wondering if there's any solutions which fit behind the monitor (ACD) or something along those lines, and maybe feature more in the way of heat dissipation. I know you can get little shelves to mount on the back of ACD's and iMacs, was wondering if anyone had taken that idea further.
Failing that, perhaps a sideways stand? The Air isn't a priority, mainly for the 17-inch, but would be good if there was a solution for the Air as well. I did a stand for it when the Air first came out for someone else and that's fine, but if I do it for myself I know I'll spend too much time nerding all the details.

I want a MBP because I'd like to experience the whole OSX thing and whatnot. I have been a windows user all my life. OSX looks great and interesting!
I have desktop right now...
AMD 64 X2 4400 @ 2.4GHZ
2 GB DDR2 RAM
A bit weak in today's standards... I get lags in FireFox after a while.
What should I get? I am going to be a Commerce student... and the reason why the 15 comes to mind is the i5 and the better GPU over the 13... the 13 still has the I2D... how much better is the i5 over the I2D? The 13 would provide much better mobility though.

If I buy a third-party SSD, how would I install it into the MBP (apart from opening up the case and replacing the HDD). Do I have to specially format it or anything? Or is it just pop in, put recovery CDs in and off I go?
Does Mac OS X Snow Leopard have TRIM support for the 256GB SSD you can upgrade through the Apple Store or any SSD for that matter?
On another hand, would a 500GB 7.2k drive decrease battery life much as opposed to 5400rpm HDD or SSD?

I have some ideas as to how I would do this, but I wanted to hear from some of you how you would go about doing it. I haven't had to do this before and I would like things to work as seemlessly as possible.
What I am working with: 320GB @ 7200 in my MBP and 2x1TB @ 7200 in the form of a WD My Book Studio Edition II, which can be organized as 2 separate drives or in RAID 0 or RAID 1.
The 3D and CAD work that I do requires me to work in windows quite a bit. Because its a smoother workflow from the 3d and cad, I do most of my PS, Illustrator and InDesign work in Windows as well. I'll probably end up creating a 120-140 GB partition for Vista to be installed on.
I'd like to be able to access all the data that I have (currently about 500GBs) from both OS's. I would also like to be able to backup both the osx and vista partitions (hopefully automated).
I've read much of the Bootcamp thread, but haven't seen a discussion covering effective ways of backing up both os's with one backup drive as I think most people have.
