When a Nokia Lumia phone with Windows Phone 8 software is connected to a computer running Windows XP, the phone may not be recognized if the computer does not have Service Pack 3. Instead, a USB connectivity error will be displayed, or the device might be recognized as an MTP device. To fix this, do the following:
1. First, install the latest Microsoft Windows XP Service Pack 3 to your PC. You can download the Windows XP Service Pack 3 from Windows Update or manually from the Microsoft web pages: http://www.microsoft.com/en-us/download/details.aspx?id=24
2. Next, install the latest Microsoft Windows Media Player 11 to your PC. You can download Windows Media Player 11 from the Microsoft web pages:
After this, reboot your PC and you will be able to browse files in your Nokia Lumia phone with Windows Phone 8 software using a USB cable and Windows Explorer.
The battery indication light should start to scroll on a few seconds in your Nokia device, if the power supply is at adequate level for charging. The problems might appear with the USB charging, when the battery is discharged and the power level is too low at the source USB port. Then it might take up to 15 minutes, before charging indicator starts to scroll. Sometimes USB port (especially USB Hub's) does not supply enough power to Nokia device. In such a case, the charging indicator does not start to scroll and the charging notification is not displayed in Nokia device.
If charging indicator does not start to scroll try first to remove and reconnect the USB cable from your device.
The workaround is to use the dedicated charger, which is connected to the wall outlet. If that is working then Nokia device and the battery are working correctly.
If the battery charging does not succeed with the dedicated charger either, then contact your local Nokia Care point or your Service Provider to check your Nokia device and charger.

Windows Phone 8: To choose when you want battery saver mode to be activated, switch Battery saver toggle to On and tap advanced.
Note: When Battery Saver is on, your phone will no longer: automatically receive email and calendar updates, update some Live Tiles and allow apps to run in the background.
If you are listening to music or otherwise using your phone, but do not want to make or receive calls, switch airplane (flight) mode on under the Settings menu.
