How old is it?

About a year, I think.

Your mac takes PC100 8 NS DIMMS, which were pretty standard. You should also be able to install PC133 DIMMS, which are backwards compatable.

DealRAM has listings of places with 512MB DIMMS (PC133)starting at around $60, with OWC having it for about $80. PC100 is about the same price [link] .

Many people recommend you send the extra bucks for OWC, as they offer lifetime advanced replacement (They send you the new, you send the bad back afterwards).

I found the OWC listing and am ready to order. Is either PC100 or PC133 preferable for any reason?

I checked the charge when I left the house this morning: 75%. When I opened it at 3 pm to make a note, it gave me a low-power warning. WTF?

Sounds like something keeps turning it back on. Is it kept in a case? A purse? A pocket?

I haven't heard about this with the Tungsten E, but my Dad this problem when he first got his Zire 71. There wasn't enough clearance between the factory flip-cover and the center button, and whenever there was any pressure on the outside of the case the PDA got turned back on. It happened often enough that the battery wouldn't last through the day.

Beej, it shouldn't make a difference, as the PC 133 just means it's made to not fail for those machines that have faster bus speeds. I checked the OWC listing, it lists your machine.

Remember how my G5 didn't come with the Airport Extreme card I ordered? Well, when I opened it up today to install the replacement card I was sent, it turns out that I already had one in there. (It just wasn't properly installed -- once I snapped it into place, it worked fine.)

So now I have an extra one. If anyone wants it, they can have it for $50. (I'll x-post in Press.)

Is it kept in a case? A purse? A pocket?

It's in a leather case inside my bag. The on button is on the top, and it's a little recessed. It's possible it's getting turned on accidentally. Maybe I'll try to make sure I put it in right-side up: maybe if it's upside down it presses against my cell and that turns it on.

Thanks for the advice!

A question about Mac networks.

When I connect to DH's computer, I am asked for a username and password, which are pre-entered, and I have no trouble mounting his computer's HD.

When he tries to connect to mine, the same thing happens, except that his password field is blank, and so he can't connect.

Neither of us has any memory of setting up usernames or passworda, or setting up anything that would require a password. I've tried "password" "apple" and any number of other good guesses, with no avail.

What can I do to let him see my hard drive?

[eta that we have no trouble with either internet or printer sharing. It's just the direct computer-to-computer connection that's being difficult.]

Tiger (and Panther) made me set up a password just to configure the computer the first time -- the same password it prompts me for when I try and update the system software -- have you tried that credential combo?
