When using my kindle reader and going to the next page all I got was a blank page and have not been able to get anything else. The reader is less than six months old.

If you are experiencing a blank page when trying to read on your Kindle, there are several things you can try to resolve the issue:
  1. Restart your Kindle: Press and hold the power button for about 20 seconds until the device restarts.
  2. Check the battery level: Make sure that your Kindle has enough charge to function properly. Connect it to a power source and let it charge for a while.
  3. Check your internet connection: If your Kindle is connected to the internet, make sure that your Wi-Fi is working properly. Try disconnecting and reconnecting to your Wi-Fi network.
  4. Check for software updates: Make sure that your Kindle is running on the latest software version. To check for updates, go to "Settings" > "Device Options" > "System Updates".
  5. Remove and re-download the book: If the problem persists with a particular book, try removing it from your Kindle and re-downloading it.
If none of these steps work, you may need to contact Amazon customer service for further assistance.

Uploaded the futura ce350 software on windows 7 several times. When open programme get an message: Connection error.Check USB cable is connected & power switch is turned on.

There are a few possible reasons to get the USB connection error. You could have a bad USB cable, a bad port (on the computer or the sewing machine). If you are using a USB hub, try a direct connection. Try a different USB 2.0 cable (type A to type B) of 6' or less in length connected to a different port. You might simply be opening the program before the driver is completely installed. Wait a few minutes after turning on the sewing machine; look for the New Hardware Found message disappear indicating that the new driver has been associated the USB device. Usually the new hardware found is announced with a beep.

If you are connected to a USB 1.0 port, you need to turn off the computer, connect the sewing machine's USB cable to both devices and then turn on the sewing machine. Then turn on the computer and wait for the driver to be installed completely. (The first generation USB protocol was not plug and play. It only recognized devices on restart/boot.)

To check if the driver for the sewing machine is found by the computer, open the Device Manager. Expand the Human Interface Devices section. If the entry for the CE-350 has an exclamation point or a red x, the driver hasn't been properly installed. If you right-click on the device, choose Properties. Check the General section to see if the computer thinks it is working. Look the events tab for details like a "Further Installation needed" message.

I hope this helps.

(Note: some USB ports do not hold the cable properly. If the cable is wobbling in the port, you might hear the Hardware found beep several times as the connection appears and disappears with the machine. Under some circumstances, the port can be damaged by high voltage demands (charging with a bad cable or too many devices on a USB hub) or a surge coming through the computer. You can sometimes check this by connecting a USB device that works on another port or machine to the port that may be faulty.)

Here's what I would try first:
  • Open Device Manager and look at the properties of the device and all USB Root Hub entries. Under the Power Management tab, deselect the check-box for "Allow the computer to turn off this device to save power".
  • Don't let the computer go into Sleep mode under Power Management.

Also, I would think a serial device might draw a lot of power, getting pretty close to the 500 ma limit imposed on USB ports. The device might be more dependable if connected to a powered USB hub, which might not have this limitation.

Hp envy dv7 laptop window 8 does not turn off, or go to sleep when closed

Hi Martin--

Sorry to hear about your trouble. When I first read your question, I automatically assumed it might have something to do with the mechanism (a latch or otherwise) which would let the computer know that the lid is shut and that it should go ahead and take a nap. While this still might be the case, there are apparently several people with similar problems so I am including a multi-step solution which will hopefully cover your problem.




Step 1:





Change your device settings:





WHY: Some devices are active - such as a wireless mouse, your network, or the HD audio - to wake or appear to prevent sleep mode. This is especially prevalent in regards to people who are always connected to their network since the advent of cable and DSL.





FIX IT:




  1. In the lower left corner of the screen, right-click and select DEVICE MANAGER from the menu


  2. Click the arrow next to the device that needs to be adjusted. Since we\'re not sure which it might be, let\'s try a few of the more obvious solutions:



    buggerou are using a wireless/optical mouse, select MICE AND OTHER POINTING DEVICES

    * If the computer is left connected to the internet connection - or to be safe, if you are using broadband like cable or DSL, select NETWORK ADAPTERS

    * To check the HD audio setting, click SOUND, VIDEO AND GAME CONTROLLERS


  3. Double click the name of the device and a PROPERTIES window will appear.


  4. If the Power Management tab is available, skip this step

    If the Power Management tab is NOT available, click the CHANGE SETTINGS button. The same Properties window opens with Power Management tab available.



    * Note: It may ask for an administrator password; this is normal.


  5. Click the POWER MANAGEMENT tab, and remove the check next to "ALLOW THIS DEVICE TO WAKE THE COMPUTER". I know it sounds tedious, but you may have to do this for each of the three devices I listed above (mice and other pointing devices; network adapters; sound, video and game controllers)


  6. Click OK, close all your windows, and restart the laptop using the windows + C keys which will allow the Charms menu to appear on the right of your screen. Click SETTINGS, then POWER, and finally RESTART


Step 2:






Check your connected devices.





WHY:


Some devices can cause/sleep standby issues. Let\'s check to see if they are causing a problem.





FIX IT:







  1. Disconnect all non-essential connected devices such as your printer, scanner, USB drive, etc.



  2. Restart the computer with only the original mouse, monitor and keyboard connected.





    If the sleep/hibernate issue is solved, one of the connected devices was causing the problem. Replace each device one at a time until you find out which ****** was causing the problem.





Step 3:






Check for problems caused by using a keyboard or mouse in a USB 3.0 port.





WHY:





When using 3.0 ports, some computers dont allow you to put the laptop to sleep using the keyboard or mouse. This usually only occurs on systems using AMD firmware so let\'s check and see if it might be the problem.





FIX IT:







  1. Check the mouse and keyboard connections


  2. If a USB 3.0 port is being used, reconnect the device to a USB 2.0 port.



    If this is the issue, you have two solutions: Avoid using your USB 3.0 ports for your keyboard and/or mouse OR go to the next step...





Step 4:





Since it sounds like the sleep and hibernate modes worked in the past, we can always resort to using System Restore to revert the computer back to a time when the mode worked. Obviously, if the modes have never worked, don\'t follow this step.





You can perform a System Restore from the CONTROL PANEL.





------



If you are still having issues:




The list of possible reasons is practically infinite. I have listed the most common and their solutions above, but if they are not working, try:

* Disabling screen savers

* Preventing startup programs from opening

* Changing your power settings

* Upgrading the BIOS and keyboard software





I hope this works for you and if you have any questions, please don\'t hesitate to ask!

Appearing on one channel in the bottom right hand corner is a correction symbol in red (a tick mark) directly underneath that are two semi circles (resembling an ear). I cannot get rid of this and it only...

CERTIFIED TV EXPERT HERE, follow this information I provided 3 long solutions to this issue/s Solution 1 Before we start taking things apart, lets try your simple remove power plug routine and power system back up. Also, please try your unit on a few different channels to see if your problem continues on each channel. Your Main Board, Power Board, T-Control Board are suspected problems at this time. Press and hold the power button for about 15 seconds, the unit should power down by itself after you have powered it on. If it does not, then do not be concerned. Let me know if the problem continues. The first link below will bring you directly to the troubleshooting guide if you need to continue forward with the same error. Additional information http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide Failed TV and Monitors: http://s807.photobucket.com/home/budm/allalbums http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com 2 Lets focus on the external portion of the TV set first (95 percent of all TV problems are related to things EXTERNAL To the tv itself) Check the physical CONNECTION of all cables by removing each wire bare or RCA and reinstalling it (Each power cable as well), once you have removed one cable, check it for fraying, and if it is already bare, splice a new fresh connection for it. 5. Check to make sure there are NO OTHER uneeded radios, system nearby. these systems, when powered on, will cause electromagnetic interference and prevent more than just severe tv interference SURGE PROTECTOR Surge protectors account for more than 75 percent of electric faults to stereo equipment. Lets start with your AC Wall outlet. It is standard in america that 220 Volts from out of these outlets. This implies that each device will be using 220 Volts (From within that grid zone). If anything including an alarm clock is plugged into any AC outlet socket in the vicinity of the stereo equipment/TV, it will cause electric outage, and prevent electronics from even turning on! Your TV needs dedicated electric power. If your TV is located in the living room then unplug everything else in the living room. Lets plug the TV set into a Dedicated socket. Check all light switches to ensure that power is on for that outlet. Check the TV cable for Fraying both on the ac wall end and where it plugs into the TV. Check all GFCI outlets to ensure that all red reset buttons are pushed in, check the circuit breakers for proper connection and they are turned on. Now, lets try the TV set without it connected to any cable services, vcr, dvd, stereo system, etc. Please respond if we have found a solution. 3 When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components. I have been working on these a long time so feel free to follow up with me

My phone only works when it's plugged into the charger

New batteries are shipped partially charged. Before you start using your device, it is recommended that you charge the battery. Some batteries perform best after several full charge/discharge cycles. You can charge the battery in two ways: • Charging the device’s battery by connecting the power adapter. • Connecting your device to a PC via the provided Mini USB cable. Note: Only the AC adapter and USB cable provided with your device should be used to charge the device. Charging is indicated by a solid amber light on the left LED indicator. As the battery is being charged while the device’s power is on, a charging icon will be shown on the title bar of the Today screen. After the battery has been fully charged, the left LED becomes green and a full battery icon appears on the Today screen’s title bar. Warning! Do not remove the battery from the device while you are charging it using the AC or car adapter. As a safety precaution, the battery stops charging when it overheats. When the low-battery warning appears, do the following: • Immediately save your current data. • Synchronize with your PC or connect the power adapter to charge the battery. • Turn off your device.
Hope this helps, let me know if I can help you with anything else.
