Question about Toshiba Satellite M35X-S149 Notebook

1 Answer

Battery does not charge

Battery will not charge while the computer is turned on with AC adapter connected. It will only charge when PC is turned off and then only intermittenly.

Have a Toshiba M35series laptop. Same problem. With AC connected battery will only discharge and will eventually discharge completely. If I turn off the PC or put it in hibernation it will charge, but only intermittently. Swapped out the power supply thinking it might be the connector but the new supply had the same issues as the old one. Thought about taking the battery out completely to see if it will run on AC only but have not tried this yet. Battery seems to discharge fine once it has been charged so I have tentatively ruled that out as the problem.

    the laptop only charges when is power off i think is the power jack

    I also have a Toshiba M35X-S349, while using the unit it went into hibernation and would not restart, I felt that maybe the battery would no longer hold a charge due to it's age, which did not explain why the unit would not run on AC, but I ordered a battery anyway.



    I installed the new battery and experienced the same problem that there was no charging indicated because the LED was not lighting up indicating a charge, but the unit which had enough power in the new battery would now start.



    I checked the male plug coming from the charging unit with a volt ohm meter and found that I did have 12 Volts DC coming into the unit, so I'm wondering if maybe the female connector on the back has somehow gone bad?



    I contacted a local repair who immediately said it was the motherboard without looking at it, I questioned this rushed diagnosis because if the MB were bad, the unit would not start with the new battery and give me a low battery warning.



    Has anybody ever heard of this?



    Thanks for any replies.

How long for battery recharging D610 ?


when the computer is turned off, the AC adapter charges a completely discharged battery to 80 percent in about 1 hour and to 100 percent in approximately 2 hours. Charge time is longer with the computer turned on. You can leave the battery in the computer for as long as you like. The battery's internal circuitry prevents the battery from overcharging. So About 2 to 3 hrs

When you connect the computer to an electrical outlet or install a battery while the computer is connected to an electrical outlet, the computer checks the battery charge and temperature. If necessary, the AC adapter then charges the battery and maintains the battery charge.
If the battery is hot from being used in your computer or being in a hot environment, the battery may not charge when you connect the computer to an electrical outlet.

3 beep sound


If a PC suddenly fails to boot properly, you should perform a hard reset as the first action. Performing the hard reset will correct many problems. If the computer still does not start properly, select your symptom from the list below to guide you to the recommended corrective actions.
  1. Disconnect all peripheral devices and remove all USB devices and SD media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
  3. Reconnect the AC power adapter (but do not insert the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a fan or other moving parts turning.
  4. If the computer does not start, the LED lights do not glow, and the display is black, you can perform one or more of the following actions to resolve the no power issue.
    • Verify the computer is receiving power from the AC adapter . Verify that the AC adapter is not damaged and is connected correctly to a working wall outlet plug. Verify AC power is connected to the system board by examining the AC adapter, wiring, and pin connection for damage. The keyboard LEDs will glow when AC power is connected to the system board. Damaged components, like the AC adapter or the pin in the power connector, may require an HP-certified repair.
    • Use a different AC power adapter . If you have access to a different AC adapter or power pack that is designed for the computer, connect it to the notebook and try to start the computer. If you own or have access to more than one notebook, verify that you are using the adapter which belongs to the notebook. CAUTION: Using a power adapter that does not meet the power requirements or has the wrong type of connector may damage the computer. On newer notebook models, connecting the wrong adapter to the notebook may cause the power LED lights to blink but not power the computer.
    • Remove the battery and boot on AC power only . A discharged or defective battery may prevent the AC adapter from supplying enough power to start the computer. To verify that power from the AC adapter is available for PC; remove the battery, connect AC power adapter, and press power button. If available, try using a different AC adapter, that is rated for the PC, and repeat this test.
    • Remove the AC adapter and boot on battery power only . A defective AC adapter may not charge the battery and prevent the computer from booting on battery power only. To verify battery power available for the PC; connect AC power adapter, allow battery to charge for 30 minutes or more, disconnect the power adapter and press power button. If available, try using a fully charged battery, of the same type, from another computer and repeat this test.
      • If LEDS do not glow and the fan or hard drive do not spin, battery may need to be replaced.
      • If tests of both the battery and the AC adapter fail, there may be a problem with system board requiring service by HP.
      • If LEDs glow and PC boots, the AC adapter may need to be replaced.
      • If LEDs glow, but PC does not boot go to LEDs glow, fan is heard, but display is black or blank section.

Hp compaq nx7400 - battery died and power cord will not turn comp


Some laptops will not power up with a completely discharged or faulty battery. Remove the battery from the laptop, plug in the power cord and try to boot the system. If the system boots, your battery needs to be replaced. Replace your battery as soon as you can, it's not a good idea to run the laptop for extended periods with an open battery bay.

When I plug in my ac adapter into my computer to charge it the green light turns off and won't charge my computer


The diagnostic procedures from the Dell User Guide are as follows:

Total Power Failure When Using a Battery
If an AC adapter is not connected to your computer, the computer's power source
is a battery. If the battery indicator flashes amber or is a steady amber, the
battery needs to be charged. If the battery is flashing green and amber, the
battery may be defective. To troubleshoot this problem, use the following
procedure.
1. Turn off the computer and peripherals, and disconnect them from AC power.
2. Reseat each installed battery by removing it and then replacing it.
3. Turn on the computer. Does the green power indicator light up?
Allow one minute for the computer to initialize its components before checking
for signs of power.
Yes. Continue to step 4.
No. Use the AC adapter to connect your computer to AC power. If the computer
operates normally when using AC power, go to step 7. If the computer does not
boot when using the AC adapter, see the previous subsection, "Total Power
Failure When Using the AC Adapter."
4. Does the battery indicator flash amber or show a a steady amber light?
Yes. The battery needs to be charged. Go step 5.
No. Go to step 7.
5. Connect the computer to AC power, and fully charge the battery.
For instructions, see the topic titled "Charging the Battery" in the online
System User's Guide.
6. As the battery charges, does the green battery indicator light up?
Yes. Go to step 9.
No. Go to step 7.
7. Is the battery indicator flashing green and amber?
Yes. Your computer may be in a hot environment. Charging the battery in this
condition may affect the life span of the battery. Continue to step 8.
No. The problem is resolved.
8. Disconnect the computer from AC power. Is the the battery indicator still
flashing amber?
Yes. You may have a defective battery. Continue to step 9.
No. The problem is resolved.
9. Remove the battery, and press its test button. Is the uppermost indicator in
the charge gauge of the battery flashing?
Yes. You have a defective battery. Continue to step 9.
No. The problem is resolved.
10. If a spare battery is available, fully charge it, and then install it in the
computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective

Battery does not charge


Hi Bucky,

Regarding the issue you are having there are 3 possible problem here. It's either the ac adapter, the battery and the motherboard of your system.

To determine the cause of the problem you may try the following steps below.

1. Try turning on your system using the ac adapter only afterwards try using the battery.
2. Try connecting the ac adapter to a different power outlet and check if that could cause a problem as well
2. If the system works with both component then it could be an issue with the system board. If this the case you might need to call your computer manufacturer and check the latest version of BIOS you have. check also if the system is under warranty for part replacement.

Keep me posted.

Thanks.

Regards,

Jeff
