    Keep an eye on the battery indicator while working with it to see if it is running on battery when plugged in, if this is the case then something is wrong with the power supply, and/or connection from the power supply. If the battery indicator shows charging all the way up to shutdown, then it could be something else like overheating.

    Do you keep it on a surface with plenty of ventilation space underneath? Using a cooling pad? Not on a couch or bed? Check the heat of the unit, does it seem like it is getting real hot.

    Does the power supply look like it is charging the battery while lugged in or is it draining the battery while plugged in still?

We got a RULU in 12/2013. It worked for 3 months and now can not charge i


Some tablet brands will not recognize certain charger brands or connections.
First, try all available connections-USB-wall inverter, and direct computer connection (making sure the computer is awake and logged in). Second, try restarting your tablet. Third, try gently wiggling the connections on both ends, to see if it recognizes a charge. Finally, leave it plugged in for a few hours, even if it says it isn't charging. You may have a trickle charge-to put it simply, the cord is not giving the device enough power to qualify as a charge, but there is power traveling through the cord. If the charge level goes up a little over that time span, you have a trickle.
If these don't work, just purchase a new charger. They're sold everywhere-Wal-Mart, Target, Best Buy, 7-Eleven, name a store and they probably sell USB charger cords.
I hope I helped.

Hi I closed my laptop to put into hibernation mode and then noticed 2 days later that the power light was stuck on and not in hibernation. Upon opening the screen back up nothing happened. No lights, no...


You can try this: Shut the computer down and unplug the power cord from the computer. Remove the battery, then push and hold the power button and sing happy birthday to it. Or wait 15 seconds. Then plug the power cord back and try turning the system on. After it boots up, providing this fixes the problem, you may then replace the battery.

Hope this helps!

I was using a hdmi cord to connect my laptop to my tv, and now all of a sudden my tv is getting no signal


Check the screen saver time out setting on your laptop.
Set the time setting that fits you.
Example: 3 hours for a typical long movie interval or no screen save.
====
Also,check the key sequence for toggle VGA and HDMI
====
After hibernate mode (check power saver setting page on Windows),the system will default back to built-in laptop display.
To prevent this from happening,set system to performance mode and do not hibernate.

My Acer One Aspire is stuck in hibernate. After it updated itself and said it was preparing to shut down, it was stuck in the preparing for shut down mode for hours. When I let the battery run down to turn...


This solution may sound stupid, but it is affective. Try to press really long time (about 1-2 minutes) on the power button of the laptop. wait for it to shut down completely. Then turn it on to see what happens.

What may have caused this is an update of any sort.

To take out of hibernation,press the power button for less than 1 second.
Then go into the control panel and disable hibernation as described below.

Disable the your mouse's "ability to wake up computer" in device manager.
Use keyboard to wake up your computer.


Click Start > Control Panel > Performance and Maintenance > Power Options > Hibernate tab.
Then clear the Enable Hibernation check box.

If this doesn't resolve the issue,Please post back.

Can't get out of hibernation


I recommend you to do it the nasty way, unplug the power cord, and detach the battery.
Also, you may need to update windows, because this will happen again and again, there is something wrong in your windows and I can not say what it is with out working on the computer.

Purchasing a Biofeedback Machine


Since there are many different types of Biofeedback techniques, there a variety of Biofeedback machines available to purchase. The theory behind Biofeedback is that we can train our body's involuntary muscles to react to certain conditions. The Biofeedback machines available to purchase for home use work the same way the practitioners' do. The machines relay information in real time about your body temperature, your brainwave patterns, your muscle tension or heart/respiration rates. Biofeedback techniques have been developed to treat conditions ranging from attention disorders to incontinence. You can purchase Biofeedback machines for use at home; but the high costs can be prohibitive. Many therapists suggest getting a simple machine that only measures one system, like your heart rate or temperature, to minimize costs of continuing your therapy at home. Follow these steps to purchase a machine you can afford comfortably. Step1 Get a diagnosis of your condition. Ask your health care practitioner about the feasibility of biofeedback therapy for that condition. Step2 Find out before you start your therapy what projection your therapist has for your course of treatment. Knowing the time frame necessary for your biofeedback to have impact on your condition will help determine the need to purchase biofeedback machines. The longer the course of treatment, the more you should invest in renting or purchasing biofeedback machines. Step3 Ask your therapist for a recommendation on what machines to lease or purchase to continue your treatments at home, if necessary. Step4 Find out whether buying these machines is covered by your insurance. If not, ask about the possibility of renting from a medical supply company. Try having your medical doctor write a letter stating medical necessity for the device and outlining the possible adverse outcomes for your condition if you don't get it. Insurance companies play the odds. If they think you'll cost them less by providing the equipment than by not providing, they may waive their policy and cover the machine.
