Most of the time my system won't recognize the presence of the battery. Occasionally the power icon indicates the battery is charging, but after it reaches about 15%, it goes blank and again tells me no battery is present. The battery is new and works on a friend's system. How can I get my system to recognize and charge the battery? Thanks.

Re: Toshiba Portege 7140CT battery problem
Your ac adapter may be the problem. Is the adapter in good condition. Try using your friends ac adapter since you have the same model laptop. If it charges up your battery and the light stays on your adapter is at fault. Then replace your adapter or the part of it that is at fault. It could be the plug or base. If that does not solve your problem check your dc port on the laptop itself. Shut it down. On the back of your laptop where you plug in the ac adapter there is a pin. Does the pin move? If it does then you have another problem. The port may need replacing which most repair shops don't do. They usually replace the main board which can be costly. Hopefully that's not the problem. Let me know if either of these are not the case then we can go from there.
Hope this solves your problem

It would help knowing what operating system is I.e. Windows 7 or 8.can you get into safe mode by repeatedly tapping f8 this should give you drop down menu for last known good configuration.choose this to see if the laptop returns you to a desktop.the battery can be checked by leaving the power supply in until you get to the open screen desktop then remove power supply and check the icon for battery bottom right.if you hover the cursor over the icon it will give battery life in percentage.batteries eventually fail mainly because people do not charge them properly.you need to run it flat occasionally and do a full recharge.once it reaches 100% take the power supply off and run it down to 20% and charge back to 80 % half a dozen times in between full charges?also in control panel there is an icon for battery whereby you can force the battery to discharge so you can re educate the full charge memory,this usually increases the stamina of a failing battery.
The green light on your power adapter is normal, this indicates that it is charging the battery. The fan within the MacBook is controlled by an internal heat sensor. The fan inside will speed up and slow down based on the internal temperatures.
The X icon for where the battery is, indicates that the battery is not connected or the system doesn't recognize the battery anymore. Meaning, you will need to buy a new battery for your computer.
Hi, it seem as if your battery is faulty you should try another battery to see if the computer will recognize when it is charging, you can also try your battery in another compaq presario computer to see if it will have the same problem.
To resolve this problem, establish that the player is charging correctly as follows:
Connect the player to a USB port on the back of a desktop PC, to a powered hub, or to a power adapter (separately available).
Check the display for the charging icon .
As the display times out after a few seconds, press any button on the player to reactivate the display.
If the battery is fully depleted, the charging icon may not be displayed.
Cup the player in your hands to check that the blue power LED behind
the Play/Pause and Options buttons is glowing on and off repeatedly. This indicates that the player is successfully charging. After 1 hour of charging, power on the unit to activate the display. The charging icon should be displayed.
Allow the player to charge for at least 6 hours. During this time, if charging from a USB port, please ensure your PC does not enter a power conservation mode (Standby, Sleep, or Hibernate) as this will interrupt charging.
the player does not indicate a charge, or will not power on after at
least 6 hours of charging, please contact Customer Support.

The icons from the left:
1. Power indocator
2. Hard Disk indicator --> it is a tube icon, not battery, but means hard drive.
3. Power Source indicator
4. Bluetooth indicator
The third from left means the power source indicator. Normally it is light green. If there is battery problem (can not charge or battery overload) it flashes amber/orange. If flashes red, it indicates that the battery power is low. You need to change the battery or connect the AC adapter.
You might try cleaning the battery compartment. Makeing sure there are no damaged pins. Often times even a single messed up pin will cause this. Also this is a very good indication of adaptor failure. If you haven't allready I suggest getting another ac adapter specific to you machine. Even a substitute will casue the same issue you are now experianceing.
Yours might be a case of a batch of factory defect batteries. Bring it back to Circuit City and ask for a replacement but ask if you can get from a different batch. If they will not agree, show them the problem and try it in their presence. Though you may also ask for a check up of the output of the adapter and its charging/powering capacity.
Another thing you can try is to power up then shutdown your laptop normally (even if have to use AC). With the PC off let the AC adapter focus on charging the battery for a couple of hours at least (overnight preferably).
Then try again using the PC battery only. If this does not work guess your back to Circuit City.
Good luck and kind regards.
