Try this quick fix first. Remove the battery, unplug the ac adapter and hold in the power button, plug the ac adapter back in and turn on.

Why wont my tablet lock and the volume keys won't work?


in settings, try to put the "sleep" timer to 2 minutes, and see if it actually locks (or sleeps:turn off the screen)... also with mine sometimes the "capture screeen" feature works (more donts than do's!) perhaps very poor quality from the buttons.
clean all the apps running, and start with a full fresh boot (turn off by holding the power button 10 secs or more, then conecting to the charging usb, press again the power button), the volume also can be set via software, again in settings.

My China Mobile Vell-com Model V222 Has been Lock When I switch On first screen was open lock code input this mobile full screen touch only 3 key are there 1 call and 2 menu 3 switch off/onWhat Can I


try power home and volume down, all at the same time. when turn's on leave fingers on power and volume then count to 10 ( seconds) and take your fingers off power and volume, should have a menu come up and use the volume button to move down to factory reset and press home button. now this will wipe all you have on the phone but as you dont know what the password is this is your only choice. hope this helps.

Tiffany ,,something real handy if you have a netbook is an external dvd /cd drive,from there you can install the operating system again--your problem is a sign of corrupted install/bad site/code/etc.Only a reinstall will properly reset your system.
Good Luck

"HP Pavilion m7580" is not


Hello,

To verify whether it's a no POST issue, press NUM LOCK or CAPS LOCK key and check whether the CAPS LOCK or NUM LOCK lights are lit or changes when you press on it. If it doesn't then it's a No POST problem.

However, if the computer screen shows the HP logo or a display then it's POSTING and is experiencing a No BOOT issue.

If the NUM LOCK or CAPS LOCK responds when you press it but there is no display, check the connection between the monitor and the CHASSIS or CPU.

If you have verified that it's a No POST issue because CAPS lock is not responding, you need to open up the chassis to do a troubleshooting procedure. Be sure to unplug the chassis to all the connections especially the power cord. Drain the power by pressing and holding the power button from 8-10 seconds.

Here are the things that you need to do after you open up the chassis.
1. Reset the Memory sticks. Connect the CHassis to the power and monitor. If no go, try turning on the computer without the memory sticks. The aim of this troubleshooting is to see a display on the screen. Any display would be a good sign. If no go. Put the memory stick back in.

2. Remove the CD drive. Turn on the computer, check for development. If no go, proceed to step 3. Just leave the cd drive removed

3. Do the same thing with the other devices like the hard drive and other devices inside. Your aim is to see a display.

Let me know if what happens and I'll get back to you.

Once you see a display. Let me know by replying to this thread.

1. Choose Start'Settings'Control Panel and double-click Regional and Language Options.
2. In the Languages tab, click the Details button.
3. In the Settings tab, you should see a button called Key Settings. It may be grayed out. If it is, click the Add button and add another keyboard layout (it doesn't matter which one). Press OK.

Caps lock


Open up an email, or something else you can type into. Click the menu button, and select "enable multitap." Then go back to the menu and select "enable suretype." That took off the cap lock for me. I just wish I knew how it turned itself on to begin with!
