Question about Toshiba Satellite A75-S226 Notebook

1 Answer

Power supply problems

Battery charging and AC power switching off. Disconnect and reconnect power supply, sometimes will reconnect power. Battery charging light illuminated on front of machine, but battery is not charging.
With battery power less than 85%, AC power will shut down and machine switches to battery power. Acts as if too much load shuts down power supply.
Installed new battery, Rayovac, same results. Cable and power supply producing proper voltage. Replaced power supply with one from another machine. Same results.

Hello,

the problem is from the motherboard. One problem with toshiba laptop, is that they overheat too much.

Check if the fan of your laptop is working and make sure you keep your laptop where there is ventilation, so that air can enter into the laptop.

You could also open up the laptop, clean every dust on the motherboard and also the fan and cooler.

That's the area you should concentrate your attention on and not the battery or AC adapter.

Take care.

No power


Try disconnecting the power supply and start it on battery only.
After you see a screen display of some kind, the power supply can be reconnected.
If this does not work, then remove the battery and start the computer using the power supply only.
After the computer start up sequence is complete, the battery can be re-inserted into the computer.

If the computer continues to misbehave on later restarts, then follow the more rigorous BATTERY RECALIBRATION Procedure below.

1. Now, after the system is up and running with both the battery inside and the power supply connected, after taking note of the current settings so that they can be restored later, set the power plan to High Perfomance, set the computer to Never Sleep on Battery and on Power Supply, disconnect the power supply and allow the computer to run until it shuts itself off due to a low battery condition. This will discharge the battery and performs phase one of battery re-calibration.

2. Next, plug in the power supply, while leaving the battery in place and restart the computer. Allow the battery to fully recharge while leaving the power plan at High Performance and the Sleep to Never. This performs phase two of battery re-calibration.

3. Then, disconnect the power supply and allow the computer to run until it shuts itself off due to a low battery condition, again, now that it has a possibly better, fuller charge than in the previous charge/discharge cycle.

4. Again, restart the computer, connect the power supply and allow it to completely charge the battery.

5. Shut down the computer, disconnect the power supply.

6. Restart the computer and allow the computer to run until it shuts itself off due to a low battery condition again.

7. Now the battery has been recalibrated. Connect the power supply, restart/resume the computer and allow the battery to fully charge again. The Power Plan and Sleep Mode can be set back to their original settings at this time.

8. The above procedure should only need to be performed every six to twelve months to recalibrate the battery.


This condition sometimes happens to my HP Presario when I have left the power supply plugged into the computer with the battery in for several days or weeks at a time, without running on the battery alone for a while to discharge and recharge it a little bit.

HP recommends that when running your computer for more than two weeks from the power supply, the battery should be removed to slow the aging of the battery, which can cause the battery to lose capacity or fail prematurely.

E system 1212 Laptop won't switch on. Power


Laptops are so integrated that usually a system failure that involves power issues such as in your case where you cant get it turn on with anything on the screen mean the mainboard (motherboard) is damaged. This usually leads to buying a new laptop or paying for the board to be replaced which usually costs as much as the laptop.

Check if the AC Adapter brick is getting warm when connected, if not then you need to replace the Adapter.

If AC Adapter brick is getting warm and still its not charging the Battery, please perform the following steps.

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter and do NOT connect the battery now.
5. Turn on the Notebook power.

Note: With an extensive use of the notebook, some times notebook would store some static charges which indeed will stop the notebook from powering up or charging the battery.
The procedure to remove this static charges from the notebook is known as power drain.
Performing a power drain procedure will not effect any personal data or delete any pictures from the hard drive on your notebook.

If issue persists, contact Notebook manufacturer for further support.

My computer shuts off randomly by itself sometimes


Shut-downs can be caused for "all manner of reasons" (including overheating).
The cause of over heating can be due to
1) fault in power supply.change the power supply.
2) Any of the internal wire connections are got loose.so turn of your computer.then unplug it from main power outlet.then remove all the exaternal wires connected to the computer.then if its laptop open the back of the laptop and check out internally if any wire of hard disk,power supply is got loose.if its proper then also remove the wire and reconnect it.but if its normal cpu and not laptop then open the cpu by removing screws and diconnect all wires and reconnect it again.then connect all the external wires as it were before and check out.
3) if its laptop then it can also be the battery issue.if the battery is not charged then also this can happen.in some cases battery is fauty so it shows its charged but actually not charged.so replace the battery and check out.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

Dell inspiron 5150 do not come on when the power button pressed


If you remove the battery and disconnect power cord, then hold power button for 20 seconds, then reconnect power cord but do not re-insert battery, and the unit powers on okay, the problem may be your battery. If there is still an intermittent problem, the power connector inside the unit may be loose and need re-soldering, or you could have a bad power supply.

The laptop doesn't boot up always.


I would try the following:
1. Remove the battery completely. If the computer boots properly several times in a row, then the battery may be causing the power supply to do strange things.
2. If you have experience removing laptop components, try removing the hard drive. Because you say the screen goes black (I assume the system powers off) sometimes after the HP logo, I doubt its Windows or a software issue.
3. If HP has a diagnostic CD you can boot to, try that.
4. It may be the power supply acting up. If it charges the battery, and if you can boot to Windows with the battery, try getting a new power supply.
5. Otherwise, it may be the motherboard of the laptop.
