nope, not afraid of getting hot. the mini little fan will run up to 6200rpm to cool my system down.
and last time i get freaked out and nervous that my uMB will burst or something, but oh well...
i don't really care anymore, cuz i know its reliable  rclxms.gif


my mac crashes a few times. most time (or can say everytime?) is crash on safari...
oh wait.. no crash.. just lag..  flex.gif

OH YA!! sifus.... wonder why sometimes i send songs via email using MAIL app in my uMB,
after i attach the song, the whole MAIL app will hang and unfortunately, i need to force quit it.
why?  icon_question.gif

Hmmm are you sending a legit song? Just joking hehehe... I don't think it hanged. Its just not responding because its attempting to upload the file onto the email server. And we know our upload links are slow, so its waiting for it to finish. Give it some minutes? But I agree... this shouldn't happen. I'm using Entourage and I don't see such a problem.

Added on October 24, 2009, 2:59 pmi realize something..
last time b4 i install SL.... when playing facebook with external monitor, clamshell closed... the fan will go up to 6200rpm and 60'c
even clamshell open with internal screen also around that...

but now, same thing but in SL.... external monitor, clamshell closed, fan is 6200rpm and 50'c+ only
and clamshell open with internal screen, fan is 3200rpm+ and 50'c....

cool? javascript:emoticon(':blush:')

I think there's an offset how the two OS revisions reports temperature. So far, I only hear of people upgrading to SL reports higher CPU temperatures. Yours seem to be the opposite. Also I remember closing the LCD lid would cause a higher temperature than leaving it open.

Sorry to ask such question, but is it better to continue charging our laptops(battery full) instead of draining the battery and charging it back full or vice versa? Which is better for our battery life sweat.gif
*
Like the rest who have said it, a typical discharge & charge cycle can be accounted from the point it is fully charged at 100% and depleted at 0% (theoretical) and recharged at 100%. Thats what we call a typical full cycle. However, it is not always as clear cut. Consider this scenario where you have a fully charged battery at 100%. You use 20% of it (remaining 80%) and then decided to charge it to full again back to 100%. That is also considered as one cycle. So you kinda waste a potential of 80% of charge for that particular cycle. It is important to note that this is not the same as 'memory effect' of older battery technologies. 'Memory effect' prevents the full effective use of the potential charge in a battery.

Some battery manufacturers have mechanisms in place to make sure a battery cell is used in a 'balanced' way. Sony uses a battery care program to limit battery cells to only charge to 80% or lower. That is to prevent it from hitting 100% in case you didn't fully deplete the charges for that cycle. Now I do not know why not hitting 100% is important but I remember back in university days where a very good indicator of a fully charged Li-ion battery is when its temperature suddenly shoots exponentially. Most charging circuitry has these fail-safe mechanism to detect voltage and temperature of the cells. Maybe that has something to do with it.

So for regular and typical usage, if you have started using the battery keep using it until it is fully depleted. And when you charge it, keep charging it until full. And continue to keep it plugged in for as long as possible especially if you don't move from one place or another. If you're mobile, do your best to find a power point. If you have to use the battery, then remember to use it until it is fully depleted. Rinse repeat and you're good to go.

By the way, it is perfectly alright to keep the battery plugged all the time. It will not harm it because battery charge circuitry is smart enough to isolate the battery and power your laptop directly from main power. However, HEAT will reduce the longevity of a battery.

Quite a good explanation. But i must say that "Sometimes"(strongly emphasize) from 80% usage and charge till 100% doesnt count as a cycle. And same goes to 30% which i tried before. Guess what for my 2months mbp is only having 9 cycles? I bring my laptop everyday to school and use it w/o magsafe. Damn happy and very satisfy about the my battery life cycles and mh.


Added on October 25, 2009, 4:14 amhttp://eshop.macsales.com/shop/Modbook found a modded mac website. saw 2 tablet there. the price is really painful.

Oh ya, I fail to mention that the counting of charge cycles is really tricky business. For one, there's no proper standard to address these 'metrics' so one manufacturer accounts cycles differently from the other. Some move into more conventional methods as long as 100% potential charge has been discharged while others are more aggressive. The truth is a battery usually outlives the manufacturer's claims provided they are well maintained and always used. Remember heat? Heat is a very bad component for Li-Ion. Cause heat changes their structure.

QUOTE(MetalZone @ Oct 25 2009, 01:16 PM)
Sorry but I beg to differ in some aspects. A lithium-ion(cobalt)/lithium-polymer battery (used in laptops) doesn't "remember" how many charge cycles it has gone through. It is simply a figure the electronics count to keep track of the battery.

Li-ion's do not have any 'memory effect' (as you mentioned) unlike Ni-MH batteries (Nickel metal hydride) which do; and isn't actually old tech compared to Li-ion-cobalt; Just different types of battery chemistries for different purposes. NiMH's prefer to have a full charge and discharge cycle, but Li-ion's aren't too happy with that. Not doing a full discharge DOES NOT "waste" that charge cycle.

Having a full charge and discharge once in a while is fine (also recalibrates the electronics monitoring the battery) but avoid doing it on purpose ALL the time (unless that's really your usage cycle then by all means use what you invested for).

A battery charging circuitry doesn't use the temperature of the battery as a charging indicator, but rather as a shutdown and disconnect mechanism, coz if you overcharge or overdischarge a lithium-ion-cobalt, you may get what you call a "thermal-runaway" potentially with flames! Instead it uses voltage as an indicator, and it varies between different battery chemistries.

To quote a fellow flashaholic... (flashlight hobbyists in other words. we live on the edge of loose li-ion cells on our devices so we know the pros/cons and dangers of these little things)
he has summed it up pretty well:
Correct me if I'm wrong though.
*
Yes, Li-Ion does not have memory effect. I remember myself specifically mentioning that its not memory effect. As mentioned before, there are areas that aren't clearly defined in how cycles are accounted for. You're right, Li-Ion likes to be charged and discharged many times. Which is why it is perfect for today's electronics and usage lifestyles. Sometimes I wonder why Sony implements charging programs like they did for their VAIOs. There must be a reason.

And of course temperature is not the only parameter charging circuitry look for. They do have dB cutoffs, voltages, and negative dB inputs. What I was saying is that fundamentally, when a Li-Ion cell approaches a fully charged state, its temperature would shoot exponentially. That is the critical nature of Li-Ion, one that is dangerous and bad for its longevity. Sorry if I wasn't clear enough. Writing in the middle of the night does seem to be blurry hehehe...

No worries, it's just a constructive discussion.  biggrin.gif
Yeah I know that u did mention that that it's not memory effect (check my post). Just wanted to clarify things further.
However, just wanna clarify something u mentioned above: "Li-Ion likes to be charged and discharged many times."
Instead, Li-ion likes to be charged but doesn't like full charge and discharge cycles (ie 100%>0%>100%>and so on).

I've not read about of the charging algorithm sony used as u mentioned, charging to 80% of the full capacity. But I can help you explain why they probably did so. Let's give an example. A lithium-ion-cobalt's typical maximum cutoff voltage is 3.2V. Let's say battery A is always recharged up to 3.2V. And battery B is always recharged up to 3.0V only. Battery B will have a longer lifespan than battery A. Because as mentioned in my previous post, i quoted that maximum charge is actually detrimental to the lifespan of the battery. The downside is that, you have less battery capacity to utilise.

Thus, to tie back to the charging parameter you mentioned, manufacturers don't make the charging circuitry to charge to the point  the "temperature shoots up" as it would be severely detrimental to the lifespan of the battery; but instead cuts off charging of at a lower voltage, say at a maximum of 3.2V for lithium-ion-cobalt for example.

*
Yup, Sony has very different thinking approach with their batteries (since their battery fiasco biggrin.gif). Its called the Battery Care program. Its meant to prevent short cycles like using 10-20% of 100% and then charge it back to full. Its a combination of hardware and software implementation. With Battery Care, the default limit of 80% is set so that it can never be charged to full thereby preventing short cycles. It can even go on more aggressive levels like 50% or any percent the user set. The downside is that you reduce the capacity potential of your battery in exchange for better longevity and service life. Besides, it also implements very different charging strategies.

Its something I don't entirely understand but I do know at the point where a battery reaches 100% charge, the temperature would go up very high. Maybe that is not healthy like you said.

Yeah, Sony VAIOs are still good. I love the VAIO X and I checked it out the other day. Really thin and vulnerable brows.gif. I noticed the CW-series are also out and the specs were really competitive. FWs aren't that bad also. I also noticed VAIO is the only computer line going all out for 64 bit Windows now.

And you're right, avoid Acer. I don't know about ASUS though.

hey guys i'm just wondering if the new 13" macbook white can swap the hdd or not? because my friend said at 5400 rpm is realllly bad.
*
Yes, you definitely can swap the HDD on your own. Use the videos provided by our friends here and make sure you have 2 screw drivers ready. 1 for the Philips (+) and 1 Torx T6 for the 4 HDD mounting screws. Without the T6 it'll be almost impossible to remove them and transfer to the new HDD. If you don't have the T6 driver, you can get it from Viewnet for RM25 (31-piece all types).

As for HDD, if you want the largest capacity then you're limited to 5400RPM drives. Most 7200RPM are either stuck at 320GB or pretty expensive that you have to settle for 250GB. In my opinion, save yourself some headache and get the WD Scorpio Blue 500GB 5400RPM 8MB HDD. This is the best available in the market and the price is really low. I have this stucked in my MBP and its really really fast. Its quiet and its cool.

One of the reasons not to get the 7200RPM is that its heaty and causes a lot of vibration. All this for a very very small increase in performance. Really... reviews have proven it. You should do some reading. Another reason is that most 7200RPM drives are only capped at 320GB. Compared to a 500GB HDD, platter for platter... the 500GB would have a higher density. A higher density platter (as with most higher capacity drives) will yield faster sequential reads and writes since each 'bits' are closer to each other. Of course a 7200RPM drive would have better random reads and write since the platter itself spins faster. But this is very debatable in the mobile platform.

In the desktop scene, no doubt.. the 7200RPM drives trumps 5400RPM anytime. But in the mobile scene, 5400RPM has been the de facto standard along with the 8MB cache. And since I do not trust Seagate HDDs anymore, so WD is really the only reliable brand I can recommend. Fujitsus too if you like OEMs.

Yes, these 2 HDD options are recommended. As long as it is cool, quiet and don't generate much vibrations I'm good with it. I heard Samsung satisfy those requirements too but ain't that fast compared to the Scorpios.

Should I get mini display port to dvi / vga if I want display on Dell ST24 LCD and Panasonic 50S10K Plasma. Worth it buy at Apple Store or Lelong/ebay selling cheaper?

On Parallels or virtualization modes, I would recommend 4GB of RAM. Running via BootCamp, 2GB is alright. Windows XP and Windows 7 are easier on the resources. But still 2GB will run unless you're dealing with a lot of programs both from Mac and Windows.

Get it from Cycom, 2nd Floor Lowyat Plaza. They have Corsairs 2GB DDR3 modules selling for RM140.

i got myself zagg invisible skin... rm110 in garage sales. very hard to apply, but at least i know my mac is protected biggrin.gif

Although now all are unibody construction but there's the aluminum material and one that is polycarbonate plastic. By the way, I kinda like the Incipio Feather for Macbook Pro better than the Speck. Both also see through. Still I'm not comfortable with the idea of wrapping something over the heat-dissipating feature of the unibody.

Still looking for a sleeve case. Nothing fancy available in KL. Machines and others don't seem to carry 13" models. Mostly 15.4 and 17". I found something decent but the design is very very classic and dull. Doesn't really match the 'MBP lifestyle' hehehehe...

Thermal performance should around the same as the Aluminum unibodies. You just lose the surface heat dissipation capability.

hey guys i have a question here regarding Airport...

Do u get disconnection often or slow connection after awhile?

My scenario is:

Using linksys wireless N modem... starting the connection speed is fast...when idle too long (overnight/restart) my Airport will not connect the router automatically...where i need to manually insert password and the most of the time the message from Airport shown " invalid password" 

I tried keying the same password and out of 4/10 times only manage to get the wireless up but the speed is slow....

However, i try to figure it out could it be router settings...but it seems everything is straight forward for the router...disable Mac Filter/ WPA password.....nothing else already....

Pls enlighten me if i need to tweak the Network utilities? Internet speed is not a prob ( i have another PC connected with LAN with the same router =new router= where my speed is good)

Ping wireless 80% packet loss.....
*
It happened to me before after extended duration of use. At one time it just loses connection and wouldn't auto-detect. I had to disable AirPort and enable it again for it to work again. Not sure if my router is the cause of the problem. But then the problem didn't come back so I didn't pursue.

Its normal. In fact CS4 uses your GPU for acceleration on some special purpose task, so I'm not surprise the overall temperature increases and cause the fan to spin faster.

I'm not sure but all I know is that different models will have their fans react differently to thermal generation. You shouldn't be concern. I'm sure its perfectly normal and it doesn't shorten the lifespan of the fan because it spins faster. It is suppose to spin faster to increase ventilation and rate of dissipation.

If wanna do defragmentation then can try out iDefrag. But it is not freeware, the shareware can only defrag a few hundred MB. If you don't wanna buy it, there are countless other utilities. To do a full defrag on the main partition (where the OS resides) you need to defrag it offline. Either through a bootCD or via a cloned partition of the main partition.

What I did was to use Carbon Copy Cleaner to clone my main partition to an external drive. Then set SL to boot from that external drive. Once booted up, start the application and perform a full defrag. Shaved a few more seconds from my boot time (average). By the way, we don't need to perform defragmentation regularly because the HFS+ (mac os file system) has built-in defragmentation prevention by keeping files together. However it doesn't optimize free space. So when your drive is almost full, you may have degraded performance or when your free space is too fragmented.

Definitely a good deal depending on the model you're interested in. I feel the polycarbonate unibody is pretty value for money. But you'll need a case for it. However, if you're in the mood for something solid and metallic, then aluminum unibody is hard to resist. If you want something nice on the wallet, take the RM4499 model and upgrade the RAM and HDD yourself. Of course if you're not sure what you're doing, then get the higher end model.

Thats absolutely what I did for my purchase. Took the entry level model and then 'spec out' the rest of it. Save me some money too. All you need is a set of special screw drivers, some knowledge of PC hardware and you're good to go.
