Laptop Won't satrt if AC adapter plugged in. Works fine on battery

Laptop works fine on battery but when AC adapter is connected nothing happens after the boot logo. I have scanned the system file with "sfc/scannow" and find some errors and fixed that. Still no improvement. Reinstalled windows didn't helped. AC adapter and DC socket in the laptop is excellent. I suspect mosfets in the charging section of motherboard. If anybody have idea about this problem? Your help is highly appreciated at all times.

SOURCE: a35 s1592 battery won;t charge

You probably have a problem with your power adapter. Since you mentioned that the battery discharges when connected to the adapter, it means that the charger is acting as a load instead of the other way around. This is a typical behavior of a defective charger.

Try to check the output of your adaptor using any voltmeter. The voltage reading should be approximately close to the voltage rating as printed at the back of your laptop. If not, then its wiser to buy a new ac adapter instead of sending it for repair to electronic shops. Most of these chargers are no longer reliable when repaired, and might cause more problem to the laptop instead.

SOURCE: Toshiba Satellite A105-S4048 problem with AC

There's not much you can do. The problem is definately with your motherboard. I'd recommend a bios update, but normally you can ONLY run a bios update if the battery and the ac are both plugged in.

This problem is pretty common among Toshiba's A105 and P105 models.

Besides replacing the motherboard there's not much you can do.

Sorry.

Check the power input jack soldered connections for cracks, resolder them as necessary.

Ensure the wattage and ampage matches. If it does, then your system board might be gone.

SOURCE: Toshiba Satellite L300 shuts down when ac power plugged in

How about this step, try to turn off the laptop itself. Remove the cables and battery just like what you did before, then press and hold the power button for 10 seconds. Then, reinsert the cables and battery on the laptop and then turn on the computer itself. If the laptop restarts, shuts down or freezes with the AC power cables, two things that you should seriously consider. It might be the power cable itself, AC cable port or the circuitry going to the motherboard. And since you have cleaned out the fan and heat sink, you have isolated that problem. Have you plug-in another power cable on your laptop? If yes, then check if it works. Otherwise, the main issue is that the AC port is loose or the circuitry of AC adapter going to the motherboard is not not working. You can re-open the unit and check the circuitry from the AC port going to the motherboard. You may check the circuitry from AC port to the power supply if it is ok. If symptom persist, please contact your local dealer...

Hello, If the battery won't charge and the laptop won't turn on but the ac adapter works with other laptops, then the problem is the port where you plugin the ac adapter. Some of the laptops has it built in to the motherboard. So you might need to have it repaired by a technician. Or if the laptop is still in warranty, you might need to send it to the manufacturer to have it repaired or replaced. But if the laptop works without the battery, or it will turn on but the battery indicator is not lighting up, you're facing one of these problems. 1. The battery itself is dead. 2. the battery bay is loose 3. the battery itself is loose Hope this helps

My laptops shut down when i put the adapter and doesn't get start up , but it's work normally with betray


Problem description:The laptop shuts off when AC power adapter is plugged in. The laptop works fine on battery power but as soon as you connect it to AC adapter, the laptop turns off.
Possible cause:1. Power adapter failure.
2. Motherboard failure.
Possible troubleshooting steps and repair solution:First of all, test the power adapter. Make sure the adapter outputs correct voltage. It's possible that the output voltage is not correct and the laptop shuts down to prevent the damage. Test your laptop with another known good power adapter.
If the problem still exists, even after replacing the adapter, most likely it's the motherboard failure. Replace the motherboard.

Averatec 3700 notebook is charged but will not power on, nothing happens when power button is pushed even when power cord is plugged in


Try to remove the battery and turn the computer on with only the AC adapter connected. If it works then the battery is failing. If it does not there is something wrong with the motherboard or the AC adapter. hopefully it is just the AC adapter. Try to borrow an AC adapter from a friend or anybody else. Make sure that the current and power rating is exactly the same. Or else you might end up with a burned laptop. It the known working AC adapter works, then it is your charger. Buy a new one.

Battery is not charging.


Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced. Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

My daughters Toshiba satellite l505d will not boot up correctly. It starts but then nothing happens. What do I need to do. Have already taken battery out and restarted. Any help would be helpful.


Try the following.
1. Remove battery and plug in the AC Adapter and check if it works
If yes - Battery is defective
If no - Motherboard Problem/AC adapter

2. Check the AC adapter LED indicator if its lighted or not(double check by a multitester)
If lighted - it works properly
if not - replace
3. Try to reinstall WINDOWS operating system by the use of the installer CD
4. Reformat your computer and install necessary drivers and applications

Thanks. Cheers!

Battery back needs to be connected to the DVD player when charging. connect the batter pack to player. Run the DC/out from the battery pack to the DC/in in the player. plug the charger into the wall.

if that does not work, you have a bad battery
