12" pBook: 80GB@5400 vs 60GB@4200 - noise, fan, battery?

Message #1 - Posted 2004/05/27 - Peter Renzland

I am considering a new pbook, and wondering whether to get the 80GB@5400 HD (vs 60GB@4200).

I like quiet.

Should I expect more noise from the drive (or less?),
and will the fan be on more, and will the battery drain faster?

I currently have a 500Mhz iBook, 10GB, 384MB. Very quiet.

Battery load is 400mA doing absolutely nothing with display and Airport off. Minimal load (editing with vi), with display at 1/16th the load is about 750mA.

I expect that the pBook load will be more than that.

Another question -- iBook display (even at 16/16th) is not really readable outside when the sun is shining, except in deep shade. Is pBook better, or the same?

Thanks for any hints,

-- Peter

Most likely, the larger, faster drive will be hotter and noisier to begin with. The fan will need to be on more often to dissipate extra heat. About the only time the fan has ever come on in my 15" AlBook, was when I was ripping a DVD off to my HDD.
The other possibility is that the 80GB is made with 2 40GB platters instead of the presumably 3 20GB platters in the 60GB. In this case, the drives might actually be on the same playing field in terms of noise and heat, or the 80GB might even be better. I don't know the makeup of either drive, so I really can't say. Sorry.

Can't give you specs on the current draw, how do you find this anyway? An app? Or do you physically disconnect the battery and drop an ammeter in there? Anyway, my 15" AlBook 1GHz, 60GB, Combo Drive runs around 3 hours with minimal use (little web-browsing w/ Airport Extreme, Word v.X, etc.) and the display at about 50% backlighting.

Nah, I don't think anything will help you in the bright shining sun (or reflective clouds for that matter!). I've been meaning to see what a pair of polarized sunglasses would do, but I'm afraid unless you are straight on, it will be even worse.

Thanks for any hints,

Your welcome,

Maybe someone with actual experience will follow up.

One way is:

I wonder if someone could (on a 12" pBook) ...

(with no apps running (except terminal), and airport off, and everything unplugged)

sudo pmset -b sleep 15 dim 1 spindown 1
sleep 600
/usr/sbin/ioreg -p IODeviceTree -n battery -w 0 | grep Battery

and report the results?

That will tell us how much the load is when the computer does nothing.

Much worse.

My iBook is not really useable outside when the sun is shining. In an open verandah, with both the iBook and my eyes in the shade, at maximum brightness, high contrast is barely readable.

I was wondering whether the pBook is better than the iBook in this regard.

My 12" Powerbook's (1 GHz FEb-2004) screen is brighter than my wife's iBook's (16VRAM, Sep. 2002). When we bought the iBook we checked the 12" & 14" iBooks on display & found the 14" notably dimmer. The sales person claimed this was in fact so, although I can also see unit-to-unit variation playing a role.

Even my 12" Pb has trouble outside but under a tree it is readable

Thanks Uli. That's what I was hoping for.

I can use my 15" PB for text outside provided the sun isn't shining on the screen, graphics is hopeless.

Polarised sunglasses didn't work for me, remember that TFT screens work through the interaction of two polarised layers so using polarised sunglasses will destroy the image.

IIRC, there was a "security laptop" that omitted the second polarising layer and the user wore polarised glasses. Without the glasses the display appeared blank, with the glasses the display came to life.

Hate to complicate things, but my iBook G4 is noticeably brighter than older iBook's. The brightness of the screens improved markedly in the year before the iBook G4 was introduced. The iBook G4 screens were as bright as the Powerbook screens of the same season (I looked at quite a few in my city), but Powerbooks have been revised since then. Of course, the quality of the 15" PB screens (not the 12") was far superior.

Thanks, that's good to know.
Hm. I wonder how battery load compares between 12" iBook and 12" Powerbook.
