Doubts over the tablet battery.(thinkpad 8)

I am Brazilian, and I have a question about the battery.
Sorry my bad English, as in Brazil is hard to find information about this device.
I see in the lenovo site that the battery lasts between 7 or 8 hours.
My tablet is the lenovo thinkpad 8, 64 gb and 2 gb of ram. Use the brightness at 35% and off bluetooth. The normal use of it, internet + games is lasting a maximum of 4:30, is this normal? Videos and nothing else came to 5:00 hours long .... I claim to replacing the battery?
Thank you all, excuse anything.
Solved!
Go to Solution.

Your battery seems fine. Battery capacity is the major disadvantage of the TP8 imho. Especially when gaming or viewing/streaming full hd content.

Doubts over the Performance in Developing a Chat application

We are developing a chat application which needs to update the chat content in the database for the duration of the chat (ie.,For the duration of a session).At the same time the page should refresh and show the current content on both ends.In addition to both these, the database tables has to be checked to detect the occurence of a Network error on both sides.
We have developed it as a Browser based chat and we have used PHP with MySQL. The performance is slow.
Can anyone give a suggestion as to whether we can develop the chat application completely from the scratch and if we do that which technology should we choose to boost the performance.
If anyone is not clear about my problem just mail me.I'll explain it in more detail.
Thanks in Advance

Hi,
I just wanted to know these following answers.
2) Network failure -- Means (either browswer got killed or data did not arrived/Page Not refreshed)
3) which WebSErver are U using?
From java, it is very easy to develop chatting application for which you can use applet and servlets for the same (if you consider the performance is the utmost importance)
Updating to the database should not be done for the duration levels rather should be done at the event levels(data change/keyboards/session -inf changes).
Im not sure about PHPs running at client but I can suggest you to use two frames .One is for typing and other one is for displaying information which basically gets the staus from the server abt other users in the chat either from the session, which would be driven by other component which is static) .
Any how, I just put my ideas (Im sure , you know all these things)

If both computers were configured identically, then they would both lose the same amount of battery life with respect to the same starting configuration - comparing apple to apples. I don't know how much the added RAM, etc. would reduce battery life, but it would be less for both models.
Battery life is a tricky subject because most mfgr.s like to suggest as long a life as possible, but often do so under a set of conditions that are not common to most users. Apple is no different. Their computers do have good battery life, however. But not likely as long as what is in the ads for the typical user.

How to Avoid another Black X Over the Battery?

Forgive me if this is already a topic. If so, please direct me to the correct thread.
I was recently working on my Late 2010 Macbook Pro 13 inch laptop when it just shutdown. It took about 5 minutes to start back up, and I immidatley noticed that there was a black X over the battery symbol, and the fan was running at a full (and a very loud) speed. I shut it down and plugged in the power cord, which only glowed very faintly.
After some googleing, I figured out what was wrong and fixed it using a different thread. I basically had to restart the SMC. The thread I used is here: http://support.apple.com/kb/HT3964
However, even though it helped me fix the problem, it didn't answer any questions. So, if you could please help me. Why did this happen to my Mac? How did resetting the SMC fix the problem? How can I avoid this problem in the future? Is this an issue with the battery, or is it something else?
I want to know what I did to make this happen and how to avoid it in the future, if it's possible. All input is appreciated. I am not very computer savy when it comes to the inner workings, so I'm hoping someone smarter than me can help me understand what just happened with my computer.
Thanks!

An SMC reset can 'fix' several battery issues -
A portable Mac doesn't appear to respond properly when you close or open the lid.
The computer sleeps or shuts down unexpectedly.
The battery does not appear to be charging properly.
The MagSafe power adaptor LED doesn't appear to indicate the correct activity
- but I've no idea why you had your problem in the first place, so I can't tell you how to avoid it in the future. Maybe you let your battery drain completely down? I don't know - but now you know the 'fix' for it should it happen again.

Black spot has appared over the battery of my macbook

I've had my macbook since August 2008. I just now noticed a black spot over the battery. Now there are some scratches at the bottom of it, but its heavily used everyday and you can see the marks where my plastic case has been for 2 years. Now do you guys think Apple will honor this with the wear and tare on it?

AppleCare would have needed to be purchased in the first year of ownership.....without AppleCare and from your description of wear and tear on the MacBook I stand by a 'no' vote on Apple doing something for you...again ask them...

Macpro 17inch just shut down while using. Tried removing battery and SMC to no avail. Have had this problem before over the last six months but would always restore. Now you just click on the power button front light stays on for 2 sec

Hi, My 17 inch Mac pro laptop just shut down and I can't get it to turn on again. This has happen multiple times over the last six months. Looked through the forum and tried removing the battery and resetting the SMC control to no avail. I was having issues also with the screen a month ago but that resolved by itself. When I took it into the genius bar for screen problems I was told I'd probably need a new CPU board because the vram may be going bad and they just don't fix that
problem. Have held off because of a potential $500 repair and awaiting ivy bridge technology. Does anyone in the community know how I can restart my portable. Right now you turn on the machine and the front light stays on for 2 sec and you hear the machine click off?

I think you may have already been told what the problem is. However look at this and maybe it will help:

Hello, I have a problem with my iphone 4 battery, it looses 20% over the night with wifi on and without receiving any phone call or notification. It also uses 1 or 2% each time I check my iphone even if it is just to check up my messages. Is it normal?

Yes this is fairly normal. When you have wifi on the phone, it drains the battery life of the device.
Here is an article that has some tips that you can follow so you can modify the settings on your device to extend it's battery life to the fullest.

My iPhone 5 has really sporadic battery percentage that jumps all over the place and every so often the phone turns off

Hi guys!
I'm having trouble with my iphone 5, the battery percentage jumps all over the place. It will be down at 14% and then I plug the charger in and it jumps to 50%, it jumps around without me plugging the charger in. Today it actually turned off twice and had the red icon to plug it in and when I plugged it in it had turned straight on and was at 27%.
Any ideas what could be causing this? Its really annoying because when I'm out I'm not really able to rely on the battery indicator being correct.
Any help would be greatly appreciated :)
Russell

Hi Boris,
That sounds really similar! I'm not sure what to so about it, I bought a mobile battery pack to charge my phone while I'm on the go as this seems to make the percentage instantly jump back up again. If I don't get any ideas on here ill probably take it in to an apple store and see if I get any joy there. I'll let u know the outcome if I do go to a store, maybe I can at least buy one at a reduced rate or something. I got my iphone 5 on the day of release so I'm outside warranty too :(

Battery all over the place

I have a three month old MBP. I often browse the forums to inform myself on what's up before it happens to me. I found out about the battery update that way, and did it. I read about the possible problems that may occur, but I am not sure my problem fits - or if it even is a problem.
My battery used to last for a really long time - 4 to 5 hrs. Now it doesn't. I usually only use my MBP for surfing and occasionally downloading music or movies from itunes (haven't done that since the bat. update tho).
After experiencing shorter and shorter up time, I decided to really keep an eye on it this morning. Last night I got the message that it was running on reserve power, (and I was too) so I plugged the power cord in and shut it down for the night. This morning I unhooked the power, started it up and the time left read 5:32 for about a second or two and then read 2:32. I used it for a few minutes, walked away - the display went to sleep - I woke it up and it read 4:50. After that I let the display sleep several times and every time I woke it up I got a different reading - all over the place. 6:xx - 3:xx -4:xx and so on. I then decided to browse this discussion area and couldn't find exactly this scenario. I have been on for about 15 minutes and the time has stayed within a range of 3:05 to 2:42. I am going to let it go into full sleep and come back to finish up this post. Oh...by the way:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 5189
Remaining Capacity (mAh): 4531
Amperage (mA): -1494
Voltage (mV): 11967
Cycle Count: 37
I'm back. Time left reads 2:22 - seems normal enough for being gone about 20 minutes. Power readings:
Battery Information:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 5188
Remaining Capacity (mAh): 3695
Amperage (mA): -1522
Voltage (mV): 11796
Cycle Count: 37
But where has my battery life gone? I guess what it says now is a true reading, but since I have only had the computer unplugged from the power for about 1.5 hours, and it has been used for only about 25 minutes, isn't this a short period of life? It used to sit practically all day on battery power only being used once in a while. I am going on vacation in two weeks and I don't think this battery will even get me through one dvd movie on the plane - on a three month old computer! Any thoughts?
sj

Sarah,
The two cruical numbers for the estimate of the time remaining are the remaining capacity and amperage. If you divide capacity by amperage you will get the time estimate.
These values update relatively slowly - about every minute or so. This can lead to weird values when your computer changes its activity quickly.
Thus, right after you wake the computer up or reactivate the screen it is likely that the amperage will be low (because it doesn't use much power in sleep mode or with the screen off) and the time estimate will be high. Similarly, just after you unplug the computer the amperage estimate will be low (because it is just the amperage drawn from the battery). I have seen estimates of over 200 hours right after I unplug the AC. But as soon as it updates it all sorts itself out.
Your battery seems to be behaving normally and 5200mAh seems about right for a 15" MBP battery. They start at around 5500mAh and decline from there. Apple suggests that you should get around 300 cycles before it drops below 80% of initial capacity (4400mAh for the 15" MBP battery).
The number one hint for getting longer life out of your MacBook is to turn the brightness of the screen down. That is typically the biggest drain on the battery.

Lightning bolt over the battery indicator flashes

What does it mean when charging and the lightning bolt over the battery indicator flashes??

It means that your phone is charging. When done charging, the lightning bolt disappears.

Help! My Mouse pad is not working properly. The arrow cannot be controlled, it just keeps jumping all over the page. How can I stop this?

There are several possible causes for this issue. Please take each of the following steps that you haven't already tried until it's resolved. Some may not apply in your case.
1. Follow the instructions in this support article, and also this one, if applicable. A damaged or defective AC adapter could be the cause, even if it's the right kind.
2. Press down all four corners of the trackpad at once and release. If there's any effect, it's likely to be temporary, and in that case the unit must be serviced or replaced.
3. Open the Bluetooth preference pane in System Preferences and delete all pointing devices other than the trackpad, if applicable. Disconnect any USB pointing devices. By a "pointing device," I mean a peripheral that moves the cursor, such as a trackpad, mouse, trackball, or graphics tablet. A plain keyboard is not a pointing device.
4. Start up in safe mode and test, preferably without launching any third-party applications. If you don't have the problem in safe mode, but it comes back when you restart as usual, stop here and post your results. Do the same if you can't start in safe mode. If there was no difference in safe mode, go on to the next step.
5. Reset the System Management Controller.
6. If you're using a Bluetooth trackpad, investigate potential sources of interference, including USB 3 devices.
7. A swollen battery in a portable computer can impinge on the trackpad from below and cause erratic behavior. If you have trouble clicking the trackpad, this is likely the reason. The battery must be replaced without delay.
8. There's a report that a (possibly defective) Thunderbolt Ethernet adapter can cause the built-in trackpad of a MacBook to behave erratically. If you're using such an adapter, disconnect it and test.
9. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.
10. If none of the above applies, or if you have another reason to think that your computer is being remotely controlled, remove it from the network by turning off Wi-Fi (or your Wi-Fi access point), disconnecting from a Bluetooth network link, and unplugging the Ethernet cable or USB modem, whichever is applicable. If the cursor movements stop at once, you should suspect an intrusion.
11. Make a "Genius" appointment at an Apple Store to have the machine and/or external trackpad tested.

How long is the iPad battery last while watching video on YouTube with 3G?

How long is the iPad2 battery last while watching video on YouTube with 3G?

My iPad 2 battery can use only ~7 hours 15mins when surfing the web using cellular data network. Is it normal?
I would say that's normal. Cellular uses more power than wifi. Your screen brightness is also a factor. Lower the screen brightness & battery will last longer.
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

HT4060 Is it true you hve to let the IPad battery get real low before you charge it?

I have been told that if I charge the iPad when it is at 1/2 charge that the iPad will start to remember that it needs charged again. I was told the iPad will think it is a in a lower charge than it actually is. So if I charge it every day at 1/2 charge by the time it gets to 1/2 charge, it will slow down or may not work. This doesn't make any sense to me. If full, is 100% 50% 20% why would the iPad think it needed charged when it was at half charge. Does it have a mind. Does it cause it to think in that position if I charge it at 1/2 charge? Does it sinc in that spot? Hope you understand what I am trying to tell you. My son is good with the computer electronics but this has me stumped?
Thank You, Judy Venema

FYI
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
