I dont get more than 2-2.5 Hours out of my MacBook Air (at lowest settings)

I have a serious problem with my MBA. I mainly use it to take notes at University. So my normal usage is: Screen brightness turned to the lowest possible point, WLAN+Bluetooth OFF and Word running.
How many hours do I get? If I'm lucky, 2.5! And I'm not surfing, I dont play any fancy games, I'm just taking notes. Most of the time the screen is completely turned off, because I dont take notes every 2 seconds.
How in the **** did Apple come up with 4.5h of wireless work? If I turn on the WLAN, set the brightness to 40% and surf the Web, I'm lucky if I get 1.5hours out of my battery.
According to iStat my battery life is at 88% with abou 60 cycles. But I'm seriously considdering to take my MBA back to the Apple Store, because it's pretty much useless for me right now with less than 2h of battery life.
Are you guys getting any better results? I googled and I found reviews that said they were able to surf the web for "close to 4 hours" with brightness at 40%. HOW is this possible???!

You should definitely be getting more than 2 hours (or so) with the configuration you're currently using. Curious, what does your battery statistics look like... Give a full charge, start using it in the configuration you normal use it and copy/paste the info (after about 20 minutes of use).

On a side note, I've seen significant battery improvement on my machine when backlight is set to max versus 20-30%. It's approximately 25-30 minutes of additional run time over a consecutive run time from 100% to 5% battery.
Secondly, AppleCare does NOT cover the battery replacement "for free." There are specific requirements that would qualify a battery for a replacement under the limited one-year warranty and AppleCare but it's not a "gimme."

I cannot get more than 12 to 14 hours out of a full charge, and with a new battery. Is the phone dying?

I cannot get more than 12 to 14 hours out of a full charge, and with a new battery. The battery has been charged at least a dozen times, so I know it's at full charge. Is the phone dying?

Do a Li-ion battery rebuild. Do a full 6-8 hour charge with device in sleep mode, next run it down to about 45-50 % and then a 4-5 hour charge. After that use your phone and take it down to 30%. Another 6-8 hour charge and then down to no lower then 20-25% and one more full 8 hour charge. At that point your battery should be rebuilt back to a normal life cycle. This should eliminate your battery problem.

Can I get more than one account on iphone microsoft exchange server

Hi all,
I was trying to get more than one account on iphone microsoft exchange server for mail, but it seems to only accept one. Is this true with everyone else out there. I guess I am one of the few people with more than one email account that uses microsoft exchange. I would love to have the convience of accessing them through iphone mail but it seems that I will be forced to use safari for the other two by typing owa... in the url.
any workaround to the one email account per iphone policy??

Yu can only have one Exchange Server account per device. This is true to iPhone and any Windows mobile device in the market. The work around is to set your other accounts that reside on an Exchange server using IMAP or POP settings as you used to do before the Version 2 update allowed you to sync directly to the Exchange Server. This methode will allow you to add as many accounts as you want or have.

How can I get more than one firewre port ?

Hello,
how can I get more than one firewire port ? I'd like to be able to connect my canon HV30 camera as well as my firewire external HD at the same time so I can use firewire to upload the videos I've taken. Is this possible?
TIA

Hi ginestre-
Many FireWire hard drives have 2 firewire ports so that you can daisy-chain devices and connect the camera that way.
Daisy-chaining is not the most reliable method, but it works, so you could buy a FireWire hub.

Any way to get more than 1000 characters in notes?

i was just wondering if there was any way to get more than 1000 characters in the notes section of the ipod. i have outlines for school and they are a lot longer than 1000 characters... i didnt know if there is a setting on itunes or the ipod or a hack or mod to make it more than 1000 character limit. thanks for the help

No.
You can use the iPod in Disk mode and copy the outlines in their native format (Word?) and put them on your own computer.

I am running a strain gage test and can't get more than 1000 samples

A formor employee left a strain gage VI that I am attempting to reuse but no matter what I do I can,t get more than 1000 samples before needing to restart the loop. In the task timing (of NI-DAQmx) I have set the acquisition mode to N Samples and the clock settings to read 65000 samples at 25 Hz. There is a DAQmx timing(sample clock) VI that resets to finite samples and 1000 per channel when I close it but I have reset it to 65500 continious samples and left it open to no avail. There is a rate input to this sample clock on the front window that I have tried setting to several different rates to no avail. The Vi will run about 15 seconds, collect 1000 samples and then ask to verify the file location to save the data to. Upon verifying the file location the VI will run another 15 sec. loop before stopping for verification again.
If the loop is stopped rather thanhaving the file verified an error is listed:
Error-200278 occurred at DAQmx Read (Analog 1d WFm NChan NSamp).vi:1
The given possible reason given is: attempted to read a sample beyond the final sample acquired.
When I stop attempting to run the VI the block diagram opens with a dark block around file creation block. I need this VI to run for 10 min. collecting samples at about 25/sec. Can someone help me figure out what I am doing wrong?
I have made screen shots of the VI and the error code to assist finding the incorrect programing.
Thank you for your help.

strain test error.doc ‏493 KB

Thank you,
I was just thinking about being able to increse the size of the doc. for better visability. I have tried working with the rate input for the DaQmx for the sample clock and it does change the frequency of sampling, but I still get just the 1000 samples. I have included Jpegs this time. I have tried to exppand the two DAQ assistants that arn't expanded but am unable to, I also am unable to find a "propertys" command to open them up and see what exactly they do. The nested while loop for output also seems strange to me. Maybe I would be better to attempt a new program but being new to the language I thought using an existing program might be best.

How do I get more than 10 Y axis chart labels on a line chart

I cannot find a way to get more than 10 y axis labels on a line chart. In AppleWorks you set your step size so a size of "10" which in my case equates to labels of 10, 20, 30, ..., 80, 90 and so on up to the MAX value. I would often have 20 or more labels. In iWork the size is the number of labels and the maximum size (number of labels) I can display is 10. With a min value of 30 and a max value of 330 each label jumps 30 points which doesn't give the resolution I need to see...and....when showing the data point values on the page in iWork they overlap each other and are unreadable even when stretched out on legal paper.

What I am calling the X axis (horizontal) you are calling the Y axis. I need more than 10 labels on the vertical axis. Space for text is not a problem. I already have done exactly what you suggest for the horizontal axis. What I need is to get 30 value labels on the vertical axis (You show 5 in your example) along with the many more than 10 I have on the horizontal axis. The 10 through 300 value labels run vertically, and roughly 90 data points, one per day covering 3 months runs horizontally with a date label every 7 days. This graph represents values recorded daily at the same time each day.

How do I get more than 99 images????

I have iDVD v2.1. I have a Mac OS X 10.2.8. I want to update my iDVD, but how can I do that? I want to have more than 99 images in a slide show, but I think I need to update it. The only update I found for 10.2.8 Macs is the iDVD 3.0.1 update, which requires iDVD 3. Can I update to iDVD 3? HOW?!?! Please somebody help. If I can't, then is there a way to get more than 99 images in a slideshow at all?

Hey,
Thank you very much. That's very helpful. Thank you for your time! I bought the hardware for OS X Tiger 10.4... and I'm having a little bit of trouble installing it. Could you possibly go to that question that I asked and have any suggestions? It's located at

Thank you so incredibly much for your time. I'd really appreciate your advice and help, because you sound like an experienced Mac user!

Adobe Web Gallery- can't get more than 10 images to show up

I am trying to create a Web Gallery from within Bridge (CS4), but I'm not having any luck getting more than 10 images to show up when I create the Gallery, even though I'm selecting nearly 50 images (all in the same folder) that I'd like to be in the Gallery. Does anyone know if there's a limit to the number of images that can be used in an AWG? I can't seem to find ANY documentation that sheds light on that subject. All I know is that no matter WHAT I do, I can only get Bridge to create a Gallery with TEN images!! Very frustrating. Any help will be greatly appreciated.

Assuming the obvious that in Bridge content panel you have selected all the
files you want in the web galery
First try a purge cache for folder using the menu Tools/purge cache for
folder when having Bridge pointed to the problem folder.
Second try a reset preferences with option key while restarting Bridge.
I wish that were the case - it's only outputing up 10 images...

RFC to XI File - can NEVER EVER get more than one record in Output file.

Hi guys
This might be related to my other post on File conversion but whatever I do I just can't seem to get more than one record in the output file
the payload from R3==> XI seems fine
for example
<?xml version="1.0" encoding="UTF-8" ?>
- <rfc:Z_XI_005_RFC xmlns:rfc="urn:sap-com:document:sap:rfc:functions">
- <IP_CUSTOMER_HEADER>
- <item>
<CUSTOMERID>1000001</CUSTOMERID>
<COMPANY>One-time ship-to</COMPANY>
<SHORT_NAME>ONE-TIME</SHORT_NAME>
<STREET />
<STREET2 />
<STREET3 />
<STREET4 />
...... more data
</item>
then next customer master data and so on
- <item>
<CUSTOMERID>1000005</CUSTOMERID>
<COMPANY>ddfask</COMPANY>
<SHORT_NAME>;LK;L</SHORT_NAME>
<STREET />
<STREET2 />
<STREET3 />
<STREET4/>
etc etc until
<HKUNNR>60000</HKUNNR>
<SALES_REGION />
</item>
</IP_CUSTOMER_HEADER>
</rfc:Z_XI_005_RFC>
All I get on the Output target file
<?xml version="1.0" encoding="UTF-8" ?>
- <ns1:MT_customer_header xmlns:ns1="http://avenue.com/xi/test">
<CustomerId>1000001</CustomerId>
<company>One-time ship-to</company>
<shortname>ONE-TIME</shortname>
.... more data
</ns1:MT_customer_header>
the <item> and subsequent records all seem to have vanished.
I must be doing something PARTICULARLY stupid as nobody else ever seems to have this problem -- I've tried almost every possible combination but still to no avail
The function module is passing a table to XI in the correct structure and the payload seems to be fine so what on earth is broken here !!!,.
Cheers
Jimbo

Thanks everybody -- it's working now
RFC call was passing data correctly
function z_xi_005_rfc.
""Local interface:
*" TABLES
*" IP_CUSTOMER_HEADER STRUCTURE ZAP_CUSTOMER_INFO_2
endfunction.
in debug mode table data was fine -- in this instance 3 records were being passed.
3 errors in mapping etc fixed (with help from SDN - thanks)
1) missing the ITEM level in the Data type (hence mapping)
2) needed 0:unbounded in the occurrence
3) also mapping Item====>Item was missing (sub fields were ok)
Points awarded
final file output ok output now ok (with 3 fields only for testing)
<?xml version="1.0" encoding="UTF-8" ?>
- <ns1:MT_customer_header xmlns:ns1="http://avenue.com/xi/test">
- <item>
<Customerid>1000001</Customerid>
<company>One-time ship-to</company>
<shortname>ONE-TIME</shortname>
</item>
- <item>
<Customerid>1000005</Customerid>
<company>ddfask</company>
<shortname>;LK;L</shortname>
</item>
- <item>
<Customerid>1000010</Customerid>
<company>One Time Customer Test</company>
<shortname>SADFIWQEFG</shortname>
</item>
</ns1:MT_customer_header>
Now only the final problem to make file content conversion work.
Once again thanks --sometimes what seem trivial or simple problems take AGES to fix until someone else gives you a clue --that's why boards like SDN are great value.
Cheers

% CPU is consistently very low, never reaches over 30%. Nothing gets more than 5% anytime!

I used to have the problem of over 100% CPU usage all the time, but the last few months, it's been the opposite problem. %CPU is never above 30%. Individual apps never get more than 10% ever, and it's more like 3-5% at any time. System and User apps are getting the same treatment.
I see Index running constantly, and all applications hang after every click or swipe.
I've verified and repaired permissions numerous times. Every time, there seems to be these little errors.
What could I try?

Problem description:
CPU % Usage is very low all the time. Even when I have many operations running, and many of them are usually high-CPU users.
This is the EtreCheck profile after having rebooted 2 times. It seems like it is running a little better now, but it still took 15 minutes to boot up. But apps are now running sometimes in the double digits!

Same here. I've been searching for a solution but have found nothing.

I dont get more than 2-2.5 Hours out of my MacBook Air (at lowest settings)
