  There is an internal battery that stores the settings of the system when the computer is turned off.  Looks like yours needs to be replaced.  Consult the manual that came with the computer and/or web support site to see if it is something that you can replace or if you need assistance, replace it.  In most computers, it is fairly easy to replace, in the majority of laptops almost impossible.

• Re: Satellite U300 hibernates when the battery is very low

  Hello

  I bought my satellite U300 141 two weeks ago.
  The computer is not put into hibernation when the battery is very low.

  I checked the settings of vista, default 2% of the battery capacity, the laptop must Hibernate. But mine is not.
  But I noticed that the battery level does not fall below 5%. I tried to change the setting of vista from 2% to 5%, but it has no effect.

  Telephone toshiba support told me to update the package of the value 'stretched out' or something like that, but it has no impact too.
  the problem is still there.

  Anyone have an answer?
  I also tried to update the BIOS, but during the upgrade process, the software told me that I can't because I'm not the administrator of the computer, I am sure I am.

  so, if someone can help me please...

  Please check first if hibernation was enabled in Vista power options.
  Then you can assign to hibernation level up to 10%

  Maybe then your laptop will be able to enter hibernation mode

  I use my MacBook Air as a desktop computer. Should I leave the charger plugged all the time or should I drain the battery and then recharge? What is the best for the battery?

  Keep the computer plugged in whenever possible.

  If you keep the computer always connected, make sure that at least twice a month

  Run it on battery until battery charge level falls to about 40-50%.

  Please don't completely discharge the battery. Discharge the battery completely will reduce wear and tear on the battery.

• What is the best for the life of the battery?

  Here is the question about the battery life:several questions about Macbook Air

  In the dominic23 question said: 'Keep the computer connected to the extent possible, if you keep the computer always connected, make sure that at least two times a month'.

  I thought that the most important factor for the battery life is movement of electrons in the battery, so we should use in battery when possible. Therefore, I do not keep the connected computer if I need to. Furthermore, I'm not the discharge of the battery, if the battery remains around 30%, then I plugged in, so there is a limit to the second sentence.

  The question is which method is the best for the life of the battery?

  Fill one or two cycles of load per month will meet the requirement of "movement of the electron".

• Windows 7 adjustable threshold less than 100% of the battery charge?

  Hello.

  I have a Clevo P170HMx which is a cell phone game impressive.

  Probably the only thing I don't like is that my battery is always 100%.  I used my laptop plugged into an electrical outlet.

  and knowing that to have my battery to 100% and always load will destroy the battery life.

  My previous laptop was an IBM Thinkpad, and it had a maximize battery gauge allows you to define the allowed charge batery

  threshold.  I got this game to start the load to 15% and stop loading at 20%.  I had this same battery from the time of purchase

  until 4 years later, I got my new laptop, the battery remained in excellent condition with load capacity full not escape

  as do other batteries when they stay at 100% and reload constantly.

  Is it possible on Windows 7 pro to change the threshold of battery charge to stop less than 100% load to save battery life

  life?  Or is it Windows software available for download that will make this recommended?

  If Windows 7 is not able to do this, I would say something in an update service pack or the next version of Windows.

  Thanks a lot for your help.

  See you soon...

  Hello

  In normal circumstances as soon as the lithium-ion battery is full, a properly functioning charger will stop the charge and will only engage when the battery voltage drops to a low level. Most of the users do not remove AC power, and this practice is safe.

  The latest Lithium-ion batterires have a limited number of Discharg/charge cycles.

  You can create a detailed report on the State of the battery to double check the battery status.

  1. go to Start / all programs / Accessories. Click on the command prompt and select run as administrator.

  2 in the command prompt window, copy / paste the following command.

  powercfg-energy-output %userprofile%\desktop\energy-report.html

  Press ENTER.

  Wait for the command to complete (usually about 2 minutes).

  This create a file named energy - report.html and place it on your desktop.

  3 go to your desktop and double-click the file to open.

  Scroll to the bottom for the battery: battery information section.

  You will see:

  Rated xxxxx

  Xxxxx full last Charge

  (Where xxxxx is a number)

  4 to calculate the amount of full Charge capacity left in the battery split the value of the last Charge full rated capacity and multiply by 100.

  For this example , use the following numbers.

  Nominal capacity 4400

  Last full 2937

  Calculator enter 2937 and divide by 4400.

  Multiply the multipliez le resultat result by 100 , then press =.

  The result will be 66,75

  This means you have 66,75% of the nominal capacity of the battery.

  Tell us what you find.

  Maybe the battery can be damaged if she continue to be plugged to the charger unit once it has been fully charged?

  No, it will not damage the battery.

  You can reload at any time, for any period of time.

  You can use the computer while loading.

  Don't deplete the battery at a low level.

• Satellite A100 - problem with the operation of the battery

  Hello!

  My laptop (I bought 1.5 years ago) has a big problem when you use with the battery.
  First of all, with a fully charged battery, the notification of "limited battery status" appears after 2 minutes of operation and after 5 minutes, he goes to the standby mode due to the level of the battery is very low.

  Then, I plug it into the AC power and the battery remains yellow for about 15 minutes light and then turns blue.
  (The battery is OK, I tested it on another satellite A100)

  What can be the problem?

  Thanks in advance!

  Maria

  Given that you have tested the battery in another satellite A100, the problem must be in the settings of your computer:

  1 > START > CONTROL PANEL > POWER SELECT THE OPTIONS ICON

  2 > you will now see a screen that shows your management food and note * one * has a tick that is a small point in a circle:

  Satellite A85-s107 white screen at startup by using the power of the battery

  When I boot A85-s107 in battery power, it is get booted up in the background, but my screen is empty.
  After that if I connect it to AC power and switch deactivation/activation of the laptop power button, the screen comes back to life.

  There is no problem when I start upward when it is connected to an electrical outlet.
  Battery is fully charged and computer will work off the battery voltage if I remove AC after boootup

  Any suggestions?

  PS:

  also note that when I remove AC and then reconnect I start the computer on two occasions that it does not start the 1st time?

  Don t need to recharge the battery if the AC adapter is plugged ;)
  Try the tips posted by Alex otherwise it of a hardware problem, in my view, there seems to be something wrong with the motherboard...

• Does not power spectrum HP ENVY Ultrabook 13-2057nr of the battery (at the level of 93% charge)

  Greeting,

  I have an unusual problem with my HP ENVY spectrum XT Ultrabook 13-2057nr.
  

  I bought this recently used computer.  The battery seems to be dead, so I replaced it with a new battery, which seems to be charge (to 93%).

  However, the computer will usually not market unless the AC adapter is plugged in.

  As a general rule, the laptop will not be under voltage battery (charged to 93%).  It will work normally if connected to the power adapter.

  From time to time, if the computer has been loading for 15 minutes or more, it will be under the battery voltage. However, if it is off, it will be only re-power-on if connected to the adapter.

  If someone had a similar problem or have thoughts?

  Thanks - Ric

  Hello Rico88,

  Welcome to the HP Forums!

  I understand that the battery does not load to 100% and has a strange behavior. To start, please try test and calibrate the battery. You should be able to know if the battery has problems.

  If the battery seems to be good, you can try to improve the performance of your battery.  For more information about improving the performance of the battery, please consult the following document: improve the performance of the battery (8 Windows 7, Vista).

  If none of this helps, you can try purchasing a spare battery if the computer is not in the warranty. If this is the case, you should be able to get a replacement in the HP support by phone. You can use this Web site for information about how to contact HP properly, based on your region: Contact HP worldwide

• BlackBerry Smartphones recent problem of fast draining of the battery

  I used my Bold 9700 every day since I got it in November.  I usually load all night 2nd or 3rd with the wall charger while I sleep and have been very happy with the battery life.  While two days ago in my office, I noticed that the battery is very low, so I used the USB cable for charging.  It seemed to work, but the charge did not seem to last because it was to be loaded the next day.  I wrote chalked it up to the possibility that it didn't load completely from the USB connection, so I plugged it in the wall charger last night as I usually do.  This morning it was fully charged, although I noticed that it was a little warmer than usual.  Now, 6 hours later, with almost no use, the unit is completely dead!  At first I thought it was out, but I plugged it in just to find the boot of the device upward once the power supply has been provided.  I checked the status of the device and he says he has 2% of the power.  No one knows what took place or give me any advice for the things I can check?  Thanks in advance to all.

  Hi and welcome to the Forums!

  Looks like you have a running application that consumes resources. Left to themselves, apps will do it. It is always important to correctly close applications when you are finished with them. Using the back or on the red button won't do that - those leave the app to decide what to do... and some let themselves memory-resident, consumes resources on your BB, slowing down the overall performance. On the contrary, to close an application, tap on and select 'Close' or 'Quit'... which force the application to be closed, freeing resources for your new use it consumed. Some applications will always be running (in general - BBMessenger, browser, homescreen, phone and Messages)... but, you should always close them properly - especially the browser... If we leave on a web page, it will not consume only additional resources, but the power of the battery as well.

  In addition, each time a random strange behavior or slow creeps, the first thing to do is a battery pop reboot. With power ON, remove the hood back and remove the battery. Wait a minute, then replace the battery and cover. Power on and wait patiently through the long reboot - about 5 minutes. See if things return to functioning. Like all computing devices, BB suffers from memory leaks and others... with a hard reboot is the best remedy. Some have taken to do this on a regular basis as a preventive measure... some as often as once a day. Others got the app QuickPull to automate a simulated Batt Pull.

  Good luck!
