Crazy idea: run your notebook without battery connected

I do this with my PC laptop: run it with the battery unplugged
I use it as a desktop machine - there's no need for the battery to be charged, used and recharged
Same with my Macbook - this a great idea - since it means your battery will have a much much much longer life
Problem: the magnetic power cored connector
Along with the iPhone and iPad, I think this is one of the genius inventions from Apple
But... for my strategy... this causes a problem - a small tug and power gone!
Power gone = laptop completely cut off = not good for the health of your hard drive + precious work lossed partially + currupted files
Just wanted to know what others thought of the idea?
+ A solution to the problem?
Thanks

>> They already make computers like this, they're called "Desktops". Been making them for decades.
LOL. OK, yes, I know
Let's say you ignore my crazy idea (which I'm sure you will)
Let's say you have a brand new notebook
12months - 18 months later, your battery is now dead
A brand new one will cost £150 (just made that up - not sure of the exact cost)
Result: you will have to spend £150!
Now let's say you follow my ingenious idea...
18 months later... 24 months... 36 months... your battery could still have 50% life left in
I actauclly spoke to Apple yesterday and asked about the warranty of the battery
They said to me that it doesnt have 12 months warranty - it has a 1000 times charge and discharge warranty
(Not entirely sure if I misunderstood the message given though)
My laptops are *always* used as a desktop - only 5% of the time do I use on my lap
Surely I am not the only one in the world to do the same??

Is it bad for the Macbook to run off AC without battery installed?

just wondering, because I'm waiting for a new battery, and the bottom feels hot even when well-ventilated.
-thanks.

The heat has nothing to do with the battery installed or not installed. See the following link
Apple Notebooks: Operating Temperatures
As mentioned in the other post the two main problems running with out a battery is processor speed halved and the possibility of losing your work if you have a power outage or the magsafe falls off.
It doesn't hurt anything just best not to do it unless you have to as your situation warrants it.

Can I use my notebook without battery inserted?

Hi,
please can I connect my Notebook to the mains and work with it if the batterie is not inserted in it's box in the device?

Hello
Its absolutely no problem using the notebook with AC/DC adapter only if no battery is inserted. :)
Battery is only necessary if your notebook isnt connected to mains.

IPod touch 5G has no GPS built-in, then why Google map does show your location without wifi connection?

Am confused with the above, based on Apple's web site, iPod touch 5G has no built-in GPS, see this page:
https://www.apple.com/ipod-touch/specs.html
However when I bring my iPod touch 5G to outside where no WiFi available, but when I move, the Google Map
on the iPod touch 5G does follow me and show my current location, though the location accuracy is not high, say, errors can be
around 10 meters or higher.
Wonder how the location information is acquired on iPod touch 5G if no GPS, no WiFi?
Thanks
David

Because wifi networks are within range of the iPod and the iPod detected them and the iPod already have the location of the networks on the iPod.
You do not have to be connected to a newwork to use the location of a netowrk.
For location the iPod uses the location of nearby routers that are in Apple's database of routers and their location. Thus it appears that Apple's database is incorrect. You do not have to be connected to the router, just within range.
Apple periodically updates their database based on information they obtain from iPhones, The iPhone has to have turned on the option to send info to Apple. no one has found another way to get the location of a router added/corrected.
You can confirm that by going to well-know place with wifi like Starbucks or McDonalds

Labwiew 8 won't start without internet connection

I have Labview 8.0 installed on a NI PXI-1050 chasis with Windows XP and Service Pack 2 installed. The problem is that Labview will not load up (it locks up at finishing initialization) if I do not have the chasis connected to the internet via ethernet connection. When I connect to the internet and reboot the computer, Labview is able to start fine. The chasis is installed in a mobile vechicle and cannot always be connected to the internet. I've read that Labview 8 needs to connect to the internet to make sure the copy it is running is legitimate? Is this copy protection messing me up? Is there a way to run Labview 8 without internet connection?
Thanks.

Where did you read this? There's an initial activation that you do when you first install LabVIEW. but there's no "phone home" each time you launch LabVIEW. I can start up LabVIEW without an internet connection.
More than likely what's causing it are services that run and/or MAX. Software firewalls installed on a computer can block this communication even it's happening on a loopback, but you said that the problem goes away once you connect to the internet, so it's likely not a firewall issue. Is the PXI chassis normally connected directly to the internet through a modem, or is it connected to a router (when it's connected)? Are you using a static IP address on your PXI chassis?

Pavilion zd7000 starts in battery mode only; runs on AC only when connected to printer by USB port

My Pavilion zd 7379ea will only start up in battery mode. AC adapter appears OK with a firm green LED, so external power supply may not be the issue here? When I'm starting up (with what's left on the battery), both the charging LED and the AC LED are constantly blinking. When turned off, the battery LED is firm, and battery appears to be charging (but which obviously is not the case). Occasionally, when computer is turned off, the AC LED is lit with a firm light.
One odd thing I noted before this happened was that the computer ran on AC only when my HP printer was connected to one of the USB ports (no battery inserted). If I disconnected the printer USB cord, the computer just died immediately; it was like the computer was powered by the printer. Later I also discovered that the same cord (where it connected to the printer) had melted from extreme overheating. I tried to update the USB drivers for each port but it didn't change things. I also tried to connect a different printer to get the computer started but it didn't work this time. I'd be extremely grateful for any comments that may solve this power supply issue (and if possible explain the stuff with the printer connection).

You unplugged a USB device while the notebook was still booted into Windows and on?
Normally that won't cause any issues but , If you did that you may have damaged your system board's Southport chip.
USB is not a plug n' play port like SATA and eSATA are.
Here is a link to the maintenence manual for your laptop series.
Is your notebook still within warranty? By the processor components listed in the manual,I believe it is probably not.

Running Oracle 10g Express without Web connection.

Hello Oracle Users/Friends
I previously used Oracle 8i on an older machine running Windows 98. No web connections required to run database. Have just installed Oracle 10g Express Edition on newer machine running XP Pro. Suddenly Web connections required for database Homepage etc. All cool. But, I just want to start database without requiring Web connections to practise plsql stuff.
It is probably an easy configuration somewhere, but could someone just explain how to start/run database without Web connection?
I also want to run the database from laptop while travelling on train and hence want to navigate through all features of Oracle 10g without web connection.
I guess a further question is simply what is the advantage of the database connecting to Web for someone like myself who is just wanting to run all queries etc locally on the base PC?
Would appreciate advice on this matter.
With thanks
John

Well, when installing XE out of the box, all remote connections from other machines are disallowed by default.
Thus only you can access the management user interface of XE. The GUI is run in a web browser, thus you will need the web connection for yourself on your local machine. This is a very good reason to have the web connection enabled ;).
In order to disallow any web connections (even from your local machine) you can use dbms_xdb.sethttpport('0'); ( http://daust.blogspot.com/2006/01/xe-changing-default-http-port.html ) .

Can Tour de Flex run without internet connection

Hi
I have installed TourDeFlex.air, but unfortunately it requires internet connection to browse the components.
Do you know if it is possible to run Tour de Flex without internet connection?

From an earlier post by Nicolas Mertens:
"here's what I got from Customer Services about this problem:
[Help] files are located in the following location:
C:/Program Files/Common Files/Adobe/Help/en_us/InDesign/6.0. Also
from that location, you can launch the file 'index.html' and this
should direct you to *the online help that you would access through
the program itself.*"
I found that the files are not at that location, but at C:/Program

Vista, by the way). "
Yours would presumably be at [the German equivalent of

Can I run my MacBook Pro Late 2008 without battery forever? Is it bad in long term or anything? Does it make the system less stable?
My battery got swollen (and I unfortunately noticed it very late and might have be running with it for months, which potentially explains all the crashes everyday and the trackpad not working anymore, the Apple test also says I have a bar of ram broken...) and I had to remove it because the back pannel did not close anymore... Can I still use my MBP normally forever that way? I was planning on buying a new mac anyway but maybe waiting for the next iMac upgrade in the year... Should I wait?

Other than the system shutting down instantly if you have a power outage, whcih could corrupt the OS. Nothing else bad will happen.

Running Mail Flow Central without direct connection?

Do we have a possibility to run Mail Flow Central (Version 1.4.0 (103)) without direct connection to the devices?
I mean: We have a local copy of (all) the logfiles, but we cannot connect directly from our local installation of MFC to the devices.
How can we "import" this logfiles on our local installation of MFC?

Thank you.
I found the directory:
MailFlowCentral\Mail Flow Central\mailFC\mgaLogs\incomingI tried the following steps:
a) I copy some files from the offline-log-directory "mail_logs" looking like [email protected]
b) I stopped and started the service "Mail Flow Central"
-> No luck: There is currently no data in the Mail Flow Central database.
c) I renamed the above files to [email protected] and repeated b).
-> No luck: There is currently no data in the Mail Flow Central database.
d) I moved the above files to the manually created \1\ and repeated b).
-> No luck: There is currently no data in the Mail Flow Central database.
e) I renamed back the above files to [email protected] still in \1\ and repeated b).
-> No luck: There is currently no data in the Mail Flow Central database.
Could you please have a look what I need else for my installed MFC-version 1.4.0-103?
In the meantime, I have added a "dummy-host" with the IP "localhost" and the logname "mail*".
Seconds after I put some of the above files (with or without the extension .001.r) the files are processed and moved to MailFlowCentral\Mail Flow Central\mailFC\mgaLogs\archive\1
Unfortunately, the results remain the same: There is currently no data in the Mail Flow Central database.
But in the host-section I found this error:Mon, 21 Apr 2008 18:10:54 +0100 Failed Unsuccessful import. Error while importing file. Import failed, an error occurred with the downloaded log file: '[Errno 13] Permission denied: '.\\mgaLogs\\incoming\\1\\[email protected]''
What kind of permission should I set (I'm trying it actually on my WinXP without any permission set on this MFC-Directories..)

RUNNING MACBOOK WITHOUT BATTERY

Hi everyone,
Is it safe to run a Macbook without a battery fitted whilst plugged into the mains or is it not advisable.
Thanks in advance,
Alan

I've bought used MacBooks off of eBay for my family, seven of them so far over the last 6 years. I've bought 8 batteries off of eBay sellers, just going with the cheapest. Only had one with a problem, it gave out after 6 cycles. That one was replaced under the warranty by the seller. The only other batteries that have been a problem were Apple branded batteries that started bulging. I've had two of those happen.
Apple doesn’t make any batteries. They buy them from the same manufacturers that the third party sellers are buying from. The only difference is that Apple has their logo imprinted on the battery.

HOW TO MAXIMIZE YOUR LAPTOP'S BATTERY LIFE

Hi all,
I had this bad experience of this wide problem in laptops, battery failure. It happens almost just after your warranty expires many will agree, funny & true..battery stops charging, shows less than 100% or 0% charge no matter how you try to charge it..etc. Also many complain that the battery shows only remaining charge time, and not the time remaining (read 9th tip below).
Though Mark, Andy, vkyr, nonny, jhem, bill, myles and other admin guys are here to help on this forum, I thought of writing this based on my own experience of these batteries till date..I had compiled a few tips and information for dummies about the use of battery here which might help you to extend battery life:
NOTE to moderatos--please check / modify / add / edit in the following if you find any wrong information.
NOTE to all -- These tips in no way will harm your system, except the 9th tip and also if you remove battery without shutting down laptop
All are welcome to add any new tips or corrections.
1. Never discharge battery to 0%. Always, ALWAYS let battery discharge to a lower limit of up to about 5 to 10%.
2. To run it or not on AC supply without battery If you use laptop most of the time at home or a place where there is a continuous (= uninterrupted) power supply, then simply remove battery from laptop and run laptop on AC power. If you are doubtful about current surge in AC supply, use a surge protector or a UPS (uninterrupted power supply) unit, which doesn't cost much. But be prepared, sometimes you may lose the data which is not saved, due to any accidental interruption. As [Bill] pointed out there might be a performance degradation due to power failure.This is not recommended if you are unsure of power supply.
3. If you use AC power most of the time, then store battery with 30 to 50% (about 40% optimum) charged condition in a dry, away from any magnetism. At least once in a week or two weeks, run the laptop on only battery supply, let discharge it to about 10%, connect to AC supply, charge battery to 100%. Shut down, disconnect supply, remove battery from laptop and then use AC power supply as usual again.
4. If you are running out of remaining battery time, then instead of shutting down PC, hibernate it ( you need to enable hibernation before through power settings in control panel). Shutting down takes more time than hibernation and without saving anything, you can resume your work after hibernation. After hibernating, even if you remove battery, it won't lose any data and will resume once you connect laptop to a power supply.
5. Use power schemes (power management profiles), modify options available in power options under control panel in windows according to your usage & habits. Instead of using a blank screensaver or a screensaver which looks cool, turn OFF monitor, use lenovo power management options or windows power schemes to do this.[Tom&Wjli2]
6. When running on batteries, to save power - reduce brightness of screen (using keys Fn + F10 to reduce, Fn + F11 to increase), mute volume & turn off any unnecessary devices that you are not going to use like (thanks to [Nicolas])bluetooth / modem / plug&play monitor / network adapters(wireless/ethernet/lan/1394) / PCMCIA adapter. Use 'control panel->system->hardware->device manager' to turn these devices on and off.
Changing color schemes to dark or black colors doesn't save power in case of LCDs. (http://savingenergy.wordpress.com/2006/11/21/saving-energy-one-monitor-at-a-time/)
7. Whatever you try, a battery has a specific life time (no. of charging/discharging cycles), and it discharges slightly/continuously over a long period even when not in use. So if your battery is giving problems after about 3 years of service, then it is time for its replacement. Don't assume that if you don't use battery more often, it will last longer, it may usually, but battery failures are unpredictable.
8. If your battery has started to show problems, it will most likely fail sooner or later. Consult experts if battery is under warranty, else buy a new one.
9. Either use lenovo's default program or you might try a program like Notebook Hardware Control (http://www.pbus-167.com/ ) to monitor your power & hardware / temperature. This program shows remaining battery time once you modify advanced options for battery. Also it shows various temperatures for CPU/HDD and warns you if temperature reaches preset limit.
Caution: though this program allows, don't try to modify voltage settings under advanced options, it can harm to your system.
Added:
10. Never run a hot laptop or a hot battery. It damages the battery/laptop, so be sure to keep temperatures within normal range.(below 140 F or 60 deg C).
11. There are few more good/advanced points added by Tom on Page 2.

Dear iamdh,
Thanks for your answer and your update of the main post. I also read the various interesting articles you mentioned.
Now, I would like to submit to you these interesting questions :
Question 1 : Please do the following test : Open Paint, enlarge to full screen, set image size at least the size of your LCD (e.g. 1500 x 1200 dots) and use bucket tool to fill the whole image in pure black. Now, go to control panel, display, screensaver tab, and select Blank screensaver and test it with the View button. DO YOU SEE A DIFFERENCE between the black screen in Paint and the blank screen of screensaver ?
I don't see any difference (I use a vaio A517S laptop with high brightness LCD), so the conclusion might be that the blank screensaver uses up the same energy than a black color screen. A 2nd experiment leads to the same conclusion more conclusively : View again the "blank" screen (in screensaver tab, View button) and play with the Fn Keys to change brighness. You will notice that that it is impacted by brightness level which means the blankscreen is NOT a real "blank". WHY IS IT IMPORTANT ? Because, if choosing the Blank screensaver uses up the same energy as a black screen, AND because the black screen doesn't make any difference with a white screen on a LCD (remember the paper you found), then, why choose the Blank screensaver !!? Or, is it the fact that colors don't make any difference with LCD which is wrong !?? At that stage, I only ask. It is logic, it is one or the other, isn't it ? Any comments welcome.
Question 2 : You remember that energy transforms into various forms : light, temperature, strength, movement, etc... Now, let's come back to LCD monitor : IF a black full screen and a white full screen uses up the same energy (youy remember the paper http://savingenergy.wordpress.com/2006/11/21/saving-energy-one-monitor-at-a-time/), then, there is a interesting point : Because the white screen gives more light than the black (you can check that in the middle of the night using your laptop as a spotlight torche !), it means that the black uses up its energy into an other form. ...What could it be, other than temperature ? LET'S PUT IT AGAIN DIFFERENTLY : The black screen and the white screen use up the same energy, but why it is used for brighter light with the white, it is used for higher temperature with the dark. WHY IS IT IMPORTANT ? Because higher laptop temperatures damage batteries quicker, then it means that we should avoid dark colors and prefer light colors in our windows settings. .. any comment welcome
Really, the central point of discussion is the fact that electricity LCD consumption is not impacted by colors, even white or black. Has it been really double checked by many ? A story to follow..
