IMac G5 display too bright

Message #1 - Posted 2005/02/03 - Mats Weber

I find the display on my 20 inch iMac G5 to be much too bright, even with the brighness control at its minimum.

Is there a way around this ?

You could try calibrating the display from the "Displays" preference pane.

I have calibrated the display, but not using the advanced settings, just the basic 1.8 gamma and 5000 K color temperature. The colors are nicer (warmer) to my taste but the screen is still too bright when working in low ambient light.

Go to system preferences and there is a icon with the name something like accessability (its for settings for the handicapped). I am not using my mac at this time so I am not sure of the exact name. There is a way to change the contrast and perhaps brightness. I have changed the contrast on my Imac20 and it seems less bright and easier on the eyes.

Universal Access.

However, it only allows you to increase the contrast (not decrease it) and has no settting for brightness.

The last two "F" keys control the display brightness. Press them to adjust the level of brightness untill you've found the sweet spot.

MACINTOSH POWERBOOK #170 LAPTOP ==================================

THANKS to all who offered advice on getting my Mac #170 to read/write Apple II disks. Som eone sent me a file for the extensions folder, and it now works!

NEED 12vDC POWER ADAPTOR: The 115v AC adaptor gives output of DC 7.5 volts, 2.0 amps, center-positive polarity. What I now want is an adaptor to run the computer from a cars cigarette lighter socket: DC 12 volts. Who has it? Would offer $10. if the adaptor is the orginal one for Mac lamptop. (Would also buy the 115V AC adapter with this one as a pair. If your Powerbook #170 is non-functioning, would bid for it also at a nominally cheap price ($10) to get it for spare parts.

REPLACE INTERNAL BATTERY FOR MAC #170: The battery inside my Mac #170 seems dead. How do I get inside to replace the battery? Where can the battery be purchased, and at approx what cost? Is it Ni-Cad or some other type? If I remove the screws from the bottom of the Mac 170, will any components fly out? Is the battery replacement user-serviceable?

Thanks, Steve Buggie buggie@unm.edu 2/17/2005

Last time I bothered looking (several years ago) Rat-shack would sell you an adjustable unit (adjustable from 1.5 to 10 volts with more than plenty amperage) that can run the beast from your car lighter socket for about $18.00. Lotsa luck finding an actual Apple-issue adapter for this rig these days - You're talking about a veritable "dinosaur" of a computer that hasn't been made for close to (if not more than) 10 years now, and its various bits and pieces are becoming relatively scarce. You might try eBay, but don't hold your breath...

Would offer $10. if the adaptor is the orginal one for Mac lamptop. (Would also buy the 115V AC adapter with this one as a pair. If your Powerbook #170 is non-functioning, would bid for it also at a nominally cheap price ($10) to get it for spare parts.

Got a couple of PB 140/170 AC adapters wired for US juice laying around here somewhere... The question is "where?"... Make me an offer, and I might be persuaded to go digging.

REPLACE INTERNAL BATTERY FOR MAC #170: The battery inside my Mac #170 seems dead. How do I get inside to replace the battery?

Pull the screws out of the bottom (You'll want a Torx bit to do that - I THINK it needs to be a "T-9", but it's been too long since I actually messed with opening one that had its original screws to say for sure - I replaced my screws with more normal phillips head screws ASAP after the first time I cracked it open, and pitched the Torx screws as being an excessive pain in the rump.)

Where can the battery be purchased, and at approx what cost?

Can't be much help here. Try Rat-shack when you go looking for adapters. I'd *GUESS* it'll run you about 6-10 dollars.

Is it Ni-Cad or some other type?

I'm pretty sure it's a 3 volt lithium cell, but not absolutely certain. Markings on mine are "Panasonic VL2320", and is definitely tagged as being 3 volts, but no indication of whether it's lithium or some other technology. Be aware that the original battery has welded-on solder tabs, and it is indeed soldered down.

If I remove the screws from the bottom of the Mac 170, will any components fly out?

Nope. Just be sure you pull the main battery before you start - If you don't, you'll likely break several fairly important tabs as you try to separate the case halves.

Is the battery replacement user-serviceable?

Only if you're not afraid of taking a soldering iron to the guts of your computer.

The battery you're looking for is soldered down on a long chunk of PC board screwed to the top case underneath the hinge, exactly in line with the phone-jack opening, just to the left of the speaker. (when looking at the gutted case from the bottom)
