Toshiba laptop suddenly loses power in case of an external power supply 5

Your machine may have been around for a long time, 1. The power failure is due to a lot of dust, CPU overheating protection, and it will automatically power off. You can use an airbag to blow air inside the air outlet of the fan, but don't use the hair dryer that you use to blow your hair, if it can produce cold air, then the computer will really hang up.

2. The power light turns orange, and it flashes and flashes, it is very likely that there is a problem with the motherboard, you try not to plug in the battery and only connect the power supply, if you unplug the power supply and battery, turn on and off a few times, and plug in the power supply again to work normally, don't repair it, because this problem may happen again soon after the repair.

1.In addition to poisoning, it is also possible that the CPU fan does not rotate or is not normal and causes the CPU to overheat, and the BIOS automatically protects the shutdown. First of all, you first listen to whether the CPU fan rotates or not, after entering the system, use software such as rabbit to detect the heat, if the CPU temperature is too hot, such as more than 80 degrees, it is likely that the fan is not normal.

If you've never dusted up, there's too much dust in your laptop, so take it apart and clean it up.

2.If you do disassemble the device, by the way, unplug the battery of the BIOS, wait a few minutes and then put it back in to reset the BIOS automatic protection memory.

If you can't solve it, send it for repair.

Unplug the battery power supply, press the power button separately for 10 times in the case of no load, and then connect it after 5-6 minutes to see if it can be turned on, if it can't be turned on, the power plug is still flashing orange light, it may be that there is a problem with the power management of the motherboard. It's better to take it for repairs.

It's too hot. Let's play 3D. I'm m100, the same.

Dust removal and heat dissipation base. Keep away from the heat. Don't block the heat vents.

1 According to the phenomenon you mentioned, it is that the battery wiring of your laptop is loose, or the power protection circuit inside the battery is damaged.

2. Insert the battery, do not use external electricity, automatically cut off the power during the start-up process or shortly after the start-up, shut down, and then press the power button, the battery light flashes, but it can't be turned on".

The battery is not powered, or the battery capacity is basically zero.

3. Insert the battery, turn on the external power, there will also be a power off and shutdown, if you are lucky to turn on, the battery has been not charged".

It means that the battery not only cannot be charged, but also has a short circuit or excessive current consumption, so that your external power can not continue to supply power and will shut down. If it is not fully charged, it means that the battery itself is damaged, or the detection circuit of the battery cannot work normally, so the computer detection means that the battery has not been fully charged.

Recommendation: Replace your laptop's battery and service the battery connector.

There's a problem with the battery! If the laptop comes with a battery, repair it can be repaired, if not, buy a new battery.

This phenomenon indicates that it looks a bit like a battery problem, and the battery has been replaced 99% of the time it is a motherboard problem

First of all, the next Master Lu takes a look at the maximum temperature of the graphics card and CPU, if the temperature is normal, you can rule out the heat dissipation problem, if the temperature is high, it means that you have a problem with the heat dissipation technology, and there is no symptom.

After eliminating the heat dissipation problem, then it is the problem of the hardware motherboard, common faults may be, temperature control signal error, poor power supply voltage filtering, etc., need to be actually checked and handled, it is recommended to find a good technical actual inspection and repair. Any notebook-related faults can be answered.

If it's normal after you reboot, then I think it's due to poor CPU cooling. Determine if your fan is working properly (if the fan is not working properly, you can only replace it). When using the laptop, try not to put it on objects that do not easily dissipate heat, such as blankets.

Sheets=. = These things are not only bad for the trio. It also generates static electricity.

Especially in winter. If the screen is still black when you reboot, then it may be that there is a problem with your motherboard, the high-voltage board of the display, and the lamp, and it is recommended to send it for repair. Note: If your own book is still under warranty, do not disassemble the computer, as the consequence of doing so is that the repair point will no longer fulfill the warranty commitment.

In addition, the automatic shutdown of the computer is mainly caused by the following reasons: 1Poor heat dissipation.

The system overheats due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, which will lead to the automatic shutdown of the computer, and the CPU temperature will be high. Also, be sure to apply silicone grease, and not more or less, just apply a thin layer on the surface of the CPU. Dust it off often.

The CPU's mesh fan is critical to the CPU's heat dissipation. 2.Memory reasons.

When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, check whether the memory is plugged into the motherboard. 3.Power issues.

The insufficient power supply of the power supply is also an important factor that causes the computer to automatically shut down, and the voltage is unstable and easy to cause the computer to shut down automatically. 4.Software factors.

Computer shutdowns caused by viruses or Trojan horses also abound, especially the recent epidemic of shockwaves, which can cause the system to reboot and shut down. If you are using Windows 2000 or Windows XP, it is recommended that you patch the blaster in time after using antivirus software, and the general problem can be solved.

The laptop is automatically powered off, and you can check it as follows.

1) First remove the battery, unplug the power plug, press and hold the power button for about 5 seconds, then plug it in to see if it can be turned on, so that Qin Ruo still can't turn on and continue the next steps.

2) Remove the battery, pull the power plug down, and use a Phillips screwdriver to open the back cover screws. There is an opening on one side of the cover, and the cover can be removed by gently cocking it along the opening with a screwdriver.

3) After removing the cover, find the memory module, and use a screwdriver to slide forward and gently unplug the clips on both sides of the memory module, so that the memory module can be released. Gently remove the memory module and wait a few moments before putting it back on.

4) Cover the cover plate in reverse according to the disassembly method, install the battery, and turn on the power button to restart.

After removing the battery, will it be restarted if I only plug in the power adapter?

1. Use Master Lu and 360 Hardware Master to test the performance of the battery. I estimate that the battery has a lot of deterioration and loss.

2. After the power is off, the battery begins to discharge slowly, and it will be charged once when the power supply is connected. At present, the best batteries are only about 1,000 times charged, and most batteries are only a few hundred times. A battery like Sanyo's, which will definitely stand out is that it can be recharged 1,000 times.

As long as it is not marked, it must only be a few hundred times. After buying a new battery, at present, it can only be connected when the battery must be used, and usually try to remove it and seal it in a plastic bag to prevent moisture.

3. Buying another spare battery and replacing the two is also an effective way to reduce the number of charges.

4. If you take the battery and plug it into the external power supply or have the same effect, has your computer been damp? It feels like the humidity caused some kind of short circuit, and the computer is protected by a power outage after the high temperature.

I guess the battery is broken....Generally, the battery life of a notebook is between 300-500 times of charge and discharge....

It may be that there is a problem with the battery pack, you can go to the after-sales office to check it.

Dude pinched his fingers and counted, Uh-huh, your battery is out.

LZ, can you use the laptop normally without using the battery and no external power supply? If you can, it means that there is a problem with your external power supply, you can find the seller of the external power supply and ask them to do an after-sales inspection for you. Thinking about it, this situation should be a problem that occurs when the power of the external power supply is less than the power of the notebook.

You can ask your external power supply seller to see what the power of this movie is, and then pair it up with your laptop, and that's it. Hope it helps you.

Disconnect the power supply, unplug the laptop battery, just plug it in again and turn it back on!

Looking for a little devil during the warranty period, how can you be cheap little devil.

Why are you so powerful, guess your size! Will it be sent for repair?

1. Use a multimeter to check whether the socket is normal and whether the power supply voltage is 220V

If the voltage is abnormal, it is recommended to replace the use environment test.

2. Use a multimeter to check whether the output voltage and current of the power adapter are consistent with the labeled.

If the gap is very large and the mains voltage is normal, it can be judged that the power adapter is faulty and the laptop power adapter needs to be replaced.

3. If the above check is normal, remove the laptop battery and do not connect an external adapter.

Press and hold the power on/off button for 5 seconds and repeat 3 times. After releasing the residual charge of the notebook, plug in the power adapter separately and power on for testing.

4. If the fault persists, check the power interface of the notebook to see if it is abnormal.

For example, looseness or cosmetic damage.

5. The above examinations are normal, basically okay.

The preliminary judgment is that the notebook motherboard is faulty. It is recommended to send the service station for repair.

First of all, see if your external power supply is still on, if not, see if you set the default option to sleep or other state when you shut down, select shutdown in the shutdown option, and then see if the power light is still on after shutting down, if not, the problem will be solved. If it doesn't work, buckle the battery down, and if the power light is still on, it's magical, hehe.
