T420 will not draw power from battery

I received my T420 today. The power manager bar at the bottom of the screen shows that there is no battery remaining with a red X over the bar. The power manager indicates "Error Detected". I tried swapping out the battery from another T420 in the office that worked fine on the other computer. I receive the same error message. When I unplug AC power, the computer shortly dies.
Any idea what the problem is and how to fix it?

Hello BrenTH,
Try uninstalling Power Manager, Power Management driver then reboot then install power management driver then Power manager back and see if it helps.

Wifi is not available where I come from. I have broadband connection where data transmission is through cell sites then to USB modem connected to a computer. The modem draws power from the computer. Will this setup work with the ipad?

iPad requires Wifi (or 3G /LTE) to connect to the Internet. You cannot connect a USB modem to the iPad.
You can create your own WiFi hotspot through your computer for your iPad to connect to, if your computer supports this functionality. All Wifi Macs and many Wifi PCs do. Check your computer manual for how to do it.

Possible to draw power from iPhone battery?

Is it possible to draw power from the iPhone battery in order to power an external device? If so, how does one go about doing it?
Thanks,

Did you ever get an answer to your question? I have the same one.
Thanks!

PB will not start/run on battery

Hey everyone,
I posted this on the power & batteries forum, but judging by the dates on the replies to other threads it seems like a VERY slow forum. So here goes...
Just got a Powerbook G4 17", 1.67 ghz 2gigs ram but I have a problem.
It will not start-up from the battery. The battery takes a charge & all the lights turn green when I press the test button. When I try to start I can hear the fans run, LOUDLY, but that's it.
However, if I use the power cord it works perfectly, with one exception. The date is reset to 1969.
I ran the hardware test, using the OS discs and everything passed.
I reset the PMU, but that didn't help. Does this mean that there is an internal battery that needs to be replaced? The manual implies that the internal battery is rechargeable, so I'm a bit confused.
Any help or info is greatly appreciated.
Thanks in advance

Yeah, weekends tend to be slow. Good time for beer drinking, right!?
Your symptoms sound similar to my 1G 17" PowerBook I was given earlier this year. Once charged, the battery will last about 30-45 minutes, drop to zero, then recharge to 100 percent WAY too fast. I had a guy at an Apple Store look at it and he said that its failing at a specific power level each time while showing "good" health" is indicative of a bad cell in the battery. Mine was five years old so he advice was to get a new one.
There is indeed an internal backup battery that is rechargeable. It's located under the optical drive and one of the USB ports is attached to it. Mine was dead when I got the computer but managed to take a charge after I left the computer plugged into the wall for several days with power off. Rechargeable batteries do have a finite life, and the backup in the PB does not have enough power to start the computer even when new.
Pull the battery and let the internal backup charge from wall power for several days and don't use the computer. Then put the main battery back and see if you can get the normal sleep behavior that gives you time to reconnect AC power when the battery dies.
Also make sure your charger is the 65W version. Mine came with a 45W version from a smaller PB and will not start without the main battery installed, even in its current sorry state.

M30x MultiDrive will not burn DVDs from Windows Movie Maker

Hi,
My M30x MultiDrive will not burn DVDs from Windows Movie Maker and other applications.
I have also had problems burning CDs (unbranded) from Windows XP, built in utility.
Does the multidrive have problems, with cheaper brand disks?
Just to note,
The laptop has been back to the support guys three times so far with various issues.
(1) The hard drive failed.
(2) The multidrive failed.
(3) The motherboard got replaced, because of power failures, it wouldnt charge the battery or recognise that the power adapter was plugged in.
Note: The harddisk, not the exhaust fan makes the most noise in mine!
Thanks

Hi
As far as I know the preinstalled burning software (i.e. record now, drag ndrop) disabled the Windows XP burning option. In this case if you want to use the Movie Maker or Windows media player burning option, you should to enable this possibility.
Please go to driver properties (right click). Please select the Recording tab. The option Enable CD recording on this drive should be marked.
I use the Nero burning software and in my opinion its a one of the best burning programs. Furthermore you should try different CD/DVD manufacturers because some CDs and DVDs are not compatible with some drives. Check the TDK CDs and DVDs. I never had any problems with these medias.
Best regards

I just upgraded to Lion 10.7.2 and it says that it will not support Power PC programs so my 2008 version of Mac Office and Intuit Quickbooks are blanked out. I need these programs. How do I proceed?

I just upgraded to Lion 10.7.2 and it says that it will not support Power PC programs and has blanked out my 2008 version of MS Office for Mac and Intuit's Quickbooks. How do I proceed to get these programs back?

Upgrade to newer versions compatible with Lion or downgrade to Snow Leopard:
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

All of a sudden this morning my iphone will not send imessages from my phone number but only from my email address. When I go to the settings for my imessages to choose where they are coming from my phone number is greyed out....Is there a way to fix this

All of a sudden this morning my iphone will not send imessages from my phone....

Hi Chas869,
Hmm, that is strange that your phone number is greyed out. There are a few things that we can try. First would be to turn iMessages off, then back on. See if you are able to select your phone number. Then if that doesn't work, turn iMessages back off, then reset the network settings....settings>general>reset>reset network settings, this will reboot the phone. Don't worry, it won't delete anything from the phone, it simulates a battery pull. Once the device comes back on, then turn iMessages back on. Keep us posted if that works!

My MacPro will not wake up from sleep after the 10.8.2 upgrade.

Since latest os upgrade to 10.8.2, my mac will not wake up from sleep.

Please read this whole message before doing anything. This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it. The purpose of this test is to determine whether your problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

TS1647 My Macbook Pro will not print anything from any program. I've reinstalled the drivers. I get an error message in Word that says, "Word could not communicate with printer." Any ideas?

My Macbook Pro will not print anything from any program. I've reinstalled the drivers. I get an error message in Word that says, "Word could not communicate with printer." Any ideas?

Be sure to try restarting, if you have not done so since this problem occurred. You should also power off the printer while you do the restart...
If that does not help, you can try resetting the printing system. Open System Preferences Print & Scan (or Print & Fax) pane. In the sidebar with list of printers, right (control) click anywhere. Select Reset printing system. You will have to add back your printers after you do this.

My iMac will not wake up from sleep after upgrading to OS X Mavericks

After upgrading to OS X, my iMac will not wake up from sleep. Each time I have to do a hard restart. Is there a fix for this problem?

Hi,
I have just had the same problem with my iMac and after upgrading to Mavericks my iMac would not wake without pressing the power off button and re-booting.
Anyway, I have since done a complete new install on my iMac and have gone 5 days without an issue with the iMac not waking. It was a bit of a pain to do but my own view so far is that the problem is linked to the upgrading of the OS instead of a clean install.
My iMac now flies with a new OS installed instead of an upgrade.

Printer will not recognize commands from computer

My computer will print to other printers, but my HP printer will not recognize commands from my desktop. My computer will allow me to choose the HP to print to and the print job will show up in the printer icon on my task bar, but my printer doesn't recognize that it's been asked to print. The printer will print when other computers ask it to. No error message comes up and the yellow light doesn't flash-- the screen just reads "Ready." The ink cartridge is less than a week old and it has plenty of paper.

Hi @blackburnenglis,
Welcome to the HP Forums!
I see that your printer will not recognize commands from your computer. I am sorry to hear this, but happy to help!
For further assistance, I will need to know:
The Product/Model Number of your printer. Follow instructions in this link. Finding Your HP Product Model Number.
If you are using a Windows or Mac Operating System, and the version number. To find the exact version, visit this link. Whatsmyos.
If the printer is connected, Wireless, Ethernet, or USB.
If the printer is able to make copies.
If the power cable is plugged into a surge protector, or directly to the wall outlet. Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector. This applies to Inkjet printers as well.
If you are using Windows, please try our HP Print and Scan Doctor, and let me know what happens!
Hope to hear from you soon!

IPad 2 will not send email from any app except from my actual email app

IPad 2 will not send email from any app (eg camara, pdf edit apps, evernote ect.) except from my actual email app. It will send email from my email account in the mail app or online. Pls help :-/

I had this problem
I hit the power button and the round button at the same time and held it until it rebooted
You get the black screen and the apple logo
When that was done I want to the app and update screen and I was able to update my apps
I suggest when you update stay on that screen until they all update
I find it sometimes get stuck updating when I leave the screen as they are updating and do other things, but I could be wrong. It just seems to me that is when it happens.
The reboot works and don't worry you don't lose anything when u reboot it's like shutting down a computer and powering it back up. Everything you had before will still be there.

Which rail(s) does XP CPU draw power from on KT3 Ultra2

I wonder if someone can just clarify the following point for me please. My understanding is that on the KT3 Ultra 2, the processor draws power from the 3.3 & (or) 5v rails and not the 12v rails. Is this correct?
Many thanks for any info that you can provide.

Cheers Wonkanoby, just wanted to make sure. I wanted get a new psu and needed to be clear on what I should be looking for as regards output ratings.

Truck stereo will play iPod touch be will not charge it's battery

My truck stereo will play the gen. 4 touch 32 GB, but will not charge it's battery. It did play and charge the battery for the nano 8GB with no problems for several years previously before switching it out with the iPod touch last week. What gives?

Sometimes this works
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
Have you contacted/went to the car system's support site?
