How long should battery last with smart cover closed?

I charged my battery yesterday, closed the smart cover, and today my battery is dead and I didn't use the iPad at all. Is this normal?

On mine it says "Wake for Network Access". That would be one.
on mine this is only on the "Power adapter" tab, not the "Battery" tab.
I may lose a couple of percent battery power per 24 hours when my MBP is in
sleep mode. I have nothing connected (external drives, etc.). And a good
battery.
wow! Something is definitely wrong here.
Unless you have a bad battery, I think there's something running on your MBP
in the background that's not letting your MBP go to sleep. I've had that
happen with a couple of programs. And once with Flash (the worst piece of
programming ever).
As an experiment, try to shut down every program running. Kind of defeats the
purpose of sleep.
oh boy. ok thanks.

How long SHOULD battery last?

I've read 100's of posts on this and have yet to get an answer--how long should I expect my battery to last when my ipod is on, with screen on (auto lock on NEVER), doing nothing, no apps open (actually I removed all apps for this test), wifi OFF, location OFF, everything possible OFF, so just the screen on. This is ipod touch 8gb "3rd" gen, has os 4.2 but problem was same before with os 3.1. I get about 8 hours before battery dies. Is this normal? Warranty is just about up and I need to decide whether to pursue this with Apple. Thanks!

Not as long as if you let the screen turn off. As lllaass mentioned, the screen uses a lot of power and as far as I know, when Apple test an iPod's battery time, it's on the assumption that you do not leave the screen on. Their figures would be based on that and it's largely the reason why watching a video has less battery time that listening to audio.
So if you're not watching video, the battery will last a lot longer if you set the auto lock to - say 1 minute. More to the point, if you're not looking at the screen, why leave it turned on?
My own choice is for the auto lock to kick in after 1 minute. That way, - if I'm browsing the music section, or reading a web page or browsing my Apps, my constant navigation around the Touch keeps the screen on. If I stop doing that and simply listen to music, after 1 minute the sreen turns off and battery time is extended.
You say that you have yet to get an answer to how long the battery should last. If you check the technical specifications for the latest iPod Touch, http://www.apple.com/ipodtouch/specs.html you'll see that playback time for video is 7 hours and playback time for audio is 40 hours from full charge. So if you have auto lock on never, I suggest that 8 hours is probably reasonable since it's the virtually same as watching video.

ICal alerts don't work with smart cover closed?

Is this by design? If I have an event set for an alarm in ical, then i have my smart cover closed to cover the iPad...the alarm won't go off until I lift the smart cover. It could be an hour or so past the event, but I won't know that until I open the cover. This basically eliminates the use of using iCal alert system.
Am I missing something? Would love for the alarm to go off to remind me of meetings etc regardless if the smart cover is closed or not.
Thanks for any advice.

Alarms beep on my iPad 2 with the cover closed. You must not have it set up correctly. Is Calendar included in your Notification Center alerts? Mine is set for Alerts, Badge App Icon ON, and View in Lock Screen ON.

How long should RAM last

I bought my MacPo just over 3 years ago with 8Gb RAM.
I have been having problems with the computer slowing down etc and had it checked.
It showed that only 2Gb RAM is functioning. The boards appear to be Ok.
The RAM were moved about to different slots on both boards to find the two which were functioning. All dust was removed and the boards reseated.
I cannot believe that 6Gb RAM would break down after such a short time.
Has anyone else had a similar problem and what should I do about it?
Regards

2009? DDR3 then. RAM fails
2006-8 used FBDIMMs that run hot, have huge RAM heat sinks and also fail.
It isn't about how long but how often they heat up and cool and could just like disk drive die in six months. RAM is not your toaster - and my coffee/espresso well I go through those a lot.

Battery question- How long should they last

I got a 15 inch MBP in August 2011. This is my first Apple laptop. I would sure appreciate some help on this one.
When I first got the computer, I would charge it and use it on and off of the AC. I read about calibrating the battery and did it once about a month ago. Then I did it a few days ago. Since I calibrated the second time, it seems the battery runs out very fast. For example, this morning the battery was fully charged. I used it for less than 10 minutes. The battery percentage read 98 I believe. I put the computer to sleep. I think about 5 hours or so latter I went to check the computer and it had gone to sleep with a depleted battery. It seems to me that going from 98% to 0 in sleep mode is not good.
Before I calibrated it seemed to do fine.
Please help me and give me any suggestions you can.
Thank you very much.

MBP's made after 2009 have pre calibrated batteries and do not need to be calibrated: http://support.apple.com/kb/HT1490
The battery should last 1,000 cycles before it reaches 80% of its original capacity. Read this:http://www.apple.com/batteries/notebooks.html

Hi,

How long should I expect my battery to last

How long should I expect my battery to last. It's about a year old.

Here's ehat i responded to another forum trooper:
Ok here aremy recommendations for your consideration:
Goto the “apple “on your top menu bar. Click 1stoption (About this Mac) a small screen will appear
andclick on “More Info...which will take to a large another smallscreen with Mac Book Pro in huge
letterslike this: MacBookPro.
Nextgo the “Systems Report” button: press.
NextUnder “Hardware” on the left you'll see “Power” click that.Volia the battery info
Nowlets do an analysis of the info: here's mine a 2 mo. Old 17” MBP:
ModelInformation:
SerialNumber:     ****************** (not shown by me)
Manufacturer:     DP
DeviceName:     ******************(not shown by me)
PackLot Code:     0
PCBLot Code:     0
FirmwareVersion:     406
HardwareRevision:     1
CellRevision:     1102
ChargeInformation:
ChargeRemaining (mAh):     7806
FullyCharged:     No
Charging:     Yes
FullCharge Capacity (mAh):     8488
HealthInformation:
CycleCount:     17
Condition:     Normal
BatteryInstalled:     Yes
Amperage(mA):     2131
Voltage(mV):     12534
OK under“Charge Information” you see my MBP currently at 7806mAh (mstands Milli
which is 10 tothe -3 power) which translates to 7.806 Amp hours in non-techiespeak. As you see on mine Full Charge Capacity is 8.488 Amp hours.
Ok under healthyou see my cycle count is 17. Your very low cycle countreflects that you are not “conditioning” your battery by runningit on battery till 5 minute warning or going to sleep and then fullyrecharging it! You've had it ~18 mo. And your dooming yourbattery to a short life. Condition your battery for a long life.
Please notethis is a super battery 2.131 Amps @ 12.534Volts which Apple says will last approximately 7 hours. Real world experience is significantly less with Lion OS installed.

How long should the battery last while surfing the web?

I'm curious to know how long the battery on my Macbook should last when just surfing the web and downloading music and videos. I'm getting about 3 hours, I have a feeling it should be a lot longer. I don't have the brightness all the way up and I dim the illuminated keys.

It really depends on your configuration and what you are doing on the web.
If you have minimum RAM, the HDD will be accessed more often, causing heat which causes the fan to come on more often, which uses up power.
While I watch youtube and other forms of streaming video, my fans are usually on, so my battery life is less.
While cruising these boards and such, my battery lasts twice as long as streaming.
3 hrs while downloading music and videos is not a bad figure.
What you might want to do is watch a 2 hour movie and document the amount of time you get from the battery.
Do the same while streaming a movie.
Do some typing and or general surfing sans streaming type stuff.
The above spans a different range of CPU and graphics usage.
Then post back your times here. You will get a better indication of battery condition.
Also, post back with how much RAM you have.

How long should my battery last on my ipod classic

how long should my battery last on my ipod classic?

Depends on its age, settings that in use on the device, what it is being used for, and whether or not it is being charged up to 100% each time (usually takes a minimum of about 4 hours or so).
According to Apple tech specs for the current iPod Classic you should be able to get 36 hours of audio playback on a full charge or up to 6 hours of video.

How long should my nc8430 laptop run with a new 14.4 volt 4400mah battery

Hi I have replaced my laptop battery with a new 14.4 volt 4400mha . with a full charge and power settings at minimal how long should it run I am getting just under 2hours is this normal with intel centrino my previous battery was getting more than three hours.
thanks

I run a 7440 mha battery on an nc4400 and on high performance with no power savings, I get about 2 hours out of it.
So, I would say for yours, that's about right.
Maybe your old battery had a higher capacity.
Did someone help you? Pay it forward. Help someone else.

How long should the battery last in between uses?

I am just wondering how long the battery should last in between uses? I find mine really goes down FAST..I just purchased this on Sunday and charged it the right amount of time as such. The first time I used it after the initial charge I was downloading 2 music albums and just left it on and by morning the battery was drained..shouldn't it have lasted at least a few days? Its an iPod touch 16g V2.
Then lastnight I had it charged and was browing youtube and in a couple hours the battery was about 1/2 way..is this normal?
Thanks for your help!

The Touch's Wireless Internet access really chews up the battery time. When you're not using the wireless, go to Settings and turn Wireless off. When you're ready to go browsing, you can always turn it back on. If you already have a wireless access set up in your abode, the Touch will quickly "re-find" it and you'll be browsing again. If you're in a public free wireless area, you'll have to log on, etc.
If I leave wireless on all the time, my iPod Touch battery life is like halved-- sometimes more. The same holds true when viewing movies or video.
Hope this helps!
Abide.
