It keeps freezing and battery wont charge


Usually when the battery doesn't hold a charge anymore (even if you've plugged it in to a power source for quite a long time), the device will not longer work ... i.e. it freezes or shuts down. That's because the GPS uses power from the battery and not from the AC power source (that is plugged in and charging the device).
Replacing the battery may bring it back to life ...

Ausus U50A power tansition problem


If you are saying your laptop shuts down when you remove the power cord then that's a sign that your battery is dead.

Batteries only have a useful life, then after that they have to be replaced. Once the useful life is up, most times the battery will not take a charge.

Some batteries will take a charge and say they are at 100% but as soon as you remove the power cord it doesn't take long before it is drained at 0%.

It just showed up with NO battery life and I have it plugged into A/C all the time. Also the lights on the left front edge are blinking. Is that normal or not?


try to check if the battery can be charge in full and how long it will last. if the indicator is still binking even plug in the AC and ongoing charge for several hour,your battery might need a replacement... for the meantime while using AC adaptor,just remove the battery pack and continue using on a power supply to avoid power interruption





hope it helps...rate my solution please....thanks

Battery has been charging to 100%. Suddenly would only charge to 76 percent. Now, after two weeks, will max at 62 percent. Computer is 1 year old. Can battery meter be recalibrated?


Pulled from Gateway's website:
Do not interrupt the battery recalibration process. If recalibration is interrupted, you must start the process over again.

  1. Close all open files and programs.
  2. Connect your notebook to AC power and allow the battery to completely charge.
  3. Disconnect the AC power and restart your notebook.Note: If the power cord plug.gif or battery baticon.gif icon does not appear on the taskbar, click the show hidden icons showhidden.gif button. If the icon still does not appear, verify thatAlways show icon on the taskbar is checked on the Power Options Properties Advanced tab.

  4. Completely discharge the battery by doing the following:

    1. From the desktop, right-click on the power icon, then select Adjust Power Properties.
    2. Click the Power Schemes tab.
    3. Click the arrow button to open the Power Schemes list, then click Always On.
    4. Click the Alarms tab.
    5. Click to remove the check mark from the Low battery alarm and Critical battery alarm checkboxes. Let the battery drain until your notebook automatically turns off.

  5. After the battery is completely drained, reconnect your notebook to AC power.
  6. Charge the battery completely until the yellow battery status indicator goes out.
  7. When you are ready to use your notebook again, do the following:

    1. From the desktop, right-click on the power icon, then select Adjust Power Properties.
    2. Click the Power Schemes tab.
    3. Click the arrow button to open the Power Schemes list, then click Always On.
    4. Click the Alarms tab.
    5. Click to select the Low battery alarm and Critical battery alarm check boxes.

I noticed my run time was getting shorter and shorter, within the first 6 months. I checked my charger and base with a V.O.M. okay. About 4.4 volts on the base about 14 volts on the direct line. I bought...


To extend Roomba's battery life and keep Roomba cleaning at peak performance: • Always keep Roomba plugged in when not in use. • Recharge Roomba as soon as possible. Waiting several days to recharge Roomba can damage the battery. • For storage off the charger, remove the battery from Roomba and store in a cool, dry place. • Blue or black batteries should be stored after Roomba has been used. • Yellow batteries should be stored after being fully charged.
16-Hour Refresh Charge If Roomba has been left off the charger for an extended period, Roomba will initiate a special 16-hour charge cycle. This extensive charge refreshes Roomba's battery and extends the battery life. While charging, Roomba's "Clean" button will pulse quickly. Note: For best results, do not interrupt this Refresh Charge.

My question is , i have 4 Argus LCM PLUS PATIENT MO NITER AND THE PROBLEM IS DOESN'T WORK IN ALTERNATIVE VOLTAGE,IT IS ONLY WORK BY BATTERY after a weak the battery is low in the display.. PLEAS ADVICE...


There are two supply systems are in your machines. One is for charging the battery, and other is for bypass AC power converted to Dc ; when AC power is present. That is when AC power is present, your machine will work on that power, and charge the battery simoultaneously. When AC power is inturupted, it will automaticaly change over to battery power. But the power consumtion of your machine is high. Therefore battery power will get downed soon. Battery is placed inside the machne only for urgent power faulure use. Not for continous use. Both the power supplies are SMPS [Switched Mode Power Supply] types. We can't prophet the reason for its failure. We are repairing such machens here. Now your machines battery charging circuit is ok. AC power bypass is faulty.

Toshiba Satellite M45-S331 willnot operate on


Hello,

You have replaced the battery and then it worked.
Try once with power draining (remove the battery and then press the power button for one minute and then again refix the battery) and check.

Thanks

IT sounds like you need to replace your battery. If your laptop (notebook) is working properly while plugged in with Ac power we know it is not your power supply.

I would visit the manufacturer's website for replacement batteries. One complaint I have read about over and over on these particular systems is that the battery life is very poor.

Dell laptop doesnt charge only runs on ac power


How long have you had the laptop as all batteries even rechargeable have a limited life span. Dell laptop batteries normally have a life span of 1 to 2 years, so you may need to buy a new one

You would need a new battery. Or charge the battery to fullest, then discharge all the way and do that a few times. That might put some life back into it. Laptop batteries tend to looes its charge no matter how much you take good care of it. 10 -20 percent a year. Thats how much they loose their charge by.
