HP laptop batteries cannot be turned on.

The HP6515 business jet I bought last year also had a similar situation that couldn't be turned on.

Since HP changed to the parity route, the market share has increased a lot, but the quality decline is also very, very obvious, and the repair rate has also increased a lot. The after-sales service is also not very good, and most of the time it will be blamed on some pirated software installed. Although piracy is not advocated, it also shows that HP's hardware compatibility is poor.

It seems that many of HP's main components, such as motherboards, have also been changed to second-tier brands, so there are many more problems. Suffer a loss and grow wise, and the next generation upgrade will never consider HP.

Problems with PCs:

1. The power adapter cannot be turned back on after shutting down or standby. Listen to some IT analysis should be the power control board has quality problems.

Solution: Unplug the power adapter and plug it back in, and everything will return to normal.

2. At some times (sometimes good and sometimes bad), the power adapter is not connected to the light battery, and it cannot be turned on after turning off or standby.

Solution: Unplug the power adapter, take out the battery, plug it back in, and everything will return to normal.

3. The battery recharge capacity is very poor, and the new battery can only last for 2 hours (only for text processing, watching movies, and listening to **). This is the worst-case scenario I've ever encountered for the time being. Dell's is much better.

4. The battery is hot, and I'm really worried about whether it will spontaneously combust. The hottest one I encountered temporarily.

5. The wireless network card is good and bad, and the after-sales service says that it is in conflict with the operating system. The system is XP, genuine disk, no online registration (also considered piracy). But it's true that hardware compatibility is problematic.

6. Conflicts with some small software, such as kugoo, will cause the system to fail to operate normally. Other computers can run, just my HP6515.

7. The touch buttons in the upper row have poor sensitivity and are often misoperated.

There aren't many of these problems, but many of them are fatal. I regret buying HP.

Have you tried to press the power button when you turn it on, and press it a little longer, to see if it works, my computer battery is not the same as using the power adapter to turn it on, just press it with the power adapter, and press it for a while if you use the battery.

The power consumption of the computer is a peak when it comes to booting, especially when it comes to fast-forward systems.

Your battery may not have enough power output. causes this.

The battery is not matched with enough power.

Step 1: Test if the battery is dead, this is the best! Just plug it in and try it.

Step 2: If it doesn't work, remove the battery and plug it in. If you can, you may need to replace the battery.

Step 3: Press the switch a few more times to release the static electricity, and then turn on the machine to try it. If it doesn't work, you can only send it to the repair station for testing.

Step 4: It is recommended to find a brand after-sales maintenance station, if it is within the warranty period, do not find other people to repair, it is easy to cause unnecessary economic losses.

Self-test instructions: Remove the battery, do not connect the power supply, press the power button for five seconds to release static electricity. Plug in the power supply, press the power button again, and listen to the computer to hear if there is a sound. If it turns out that it is not a problem with the power supply, you can proceed to the next step and find the problem.

Maintenance suggestions: free after-sales maintenance within the warranty! Be sure not to be polite, the out-of-warranty after-sales service is to replace the motherboard with a new one. Bad motherboards can be used as a backup after repair, and it is personally recommended to find a better motherboard repairer, the cost will be smaller.

Summary. It is recommended that you try saving your important personal files and letting the machine sit to see if it turns on properly.

1.You first remove both the external power supply and the battery;

2.Press and hold the power button for about 15 seconds without a power supply device;

3.Then do not connect the power supply equipment and let it stand for about 40 minutes;

4.Do not plug in the battery after standing, only use the external power supply for power supply, connect the machine end of the power supply first, and then connect the socket to see if it can be turned on;

If it fails to turn on, it may be a problem with the power adapter or motherboard power interface, and you need to contact your local repair center for testing.

The HP laptop has removed the battery and cannot be turned on when plugged in. It can be used normally with the battery installed. It's useless.

Hello, I have seen your question and am sorting out the answer, please wait a while

It is recommended that you try to save your important personal files and let the machine sit to see if it can turn on normally1You first remove both the external power supply and the battery; 2.In the absence of power supply equipment, press and hold the power button for about 15 seconds; 3.

Then do not connect the power supply equipment and let it stand for about 40 minutes; 4.After standing, do not plug in the battery of Companion Hui, only use the external power supply for power supply, first connect the machine end of the power supply, and then connect the socket to see if it can open the plex or the machine; If it fails to turn on, it may be a problem with the power adapter or motherboard power interface, and you need to contact your local repair center for testing.

It is recommended to call to confirm the specific time schedule of the maintenance center, and if you cannot get through on the weekend**, it is recommended to call from Monday to Friday.

We hope you find the above reply helpful.

Solution 1: Use software to flash the battery.

IBM notebooks provide a "Battery Maximiser and Power Management" software, through which we can solve the problem of incorrect battery capacity display and reduced battery life. Running this software, the computer will automatically calibrate and discharge the battery according to the state of the battery, and when the program is over, you can find that the gap between the actual capacity of the battery and the design capacity will be smaller (but still exists).

Solution 2: Use the firmware to flash the battery.

Some manufacturers have embedded the battery correction program in the BIOS firmware (such as ASUS), and we only need to enter the BIOS to perform the battery correction program when the computer is turned on.

Solution 3: Replace the battery cell or deeply discharge.

If the battery is due to the aging of the battery, we can only solve the problem by replacing the battery cell or deep discharge, but these actions may cause the battery to be damaged or unusable, so remember to be careful before moving.

The causes and solutions are as follows:

1.Laptops may not charge after a power supply is exhausted, and the laptop is shut down or otherwise abnormally shut down.

2.At this time, restart the computer first to try if it is okay, if it doesn't work, turn it off, and then turn the laptop over.

3.Take the battery out, and when the battery comes down, set it aside and wait 10 minutes.

4.Then put the battery up, and the installation process is to press it first. Restart your computer again.

5.Then turn on the power of the laptop and you will find that the power supply shows that the battery is charging.

6.If it still can't be charged, send it to a repair shop for treatment.

According to the original factory repair! I can't help it! ~

Yes??? Charge overnight? Dizzy!!

Laptop charging can be done while playing with the notebook, and it can be charged. (plug in) while playing and charging, it will be full in an hour and a half!!

I don't understand hi me.

Unplug the battery and use the power supply to plug it in and turn it on.

Unplug the power supply to use the battery, and detect if there is an error.

Unplug the battery, plug in the battery after two minutes, and test. Shutdown charging direct plug-in can be turned on, shutdown charging is not good, it is likely to be a battery failure, it is recommended to call the national after-sales ** or go directly to the maintenance station for maintenance.

Concentrate; The battery is generally warranted for six months and one year.

1. It is recommended to try to reinsert the battery. If it doesn't work well, this situation may be caused by a faulty battery, and it is recommended to use HP's battery testing software to check the battery. If there is a problem with the battery hardware, contact the Gold Service Center for testing and processing.

You can find the nearest HP Care Pack Service Center by following **.

2. If you can't find the battery detection software of the machine, it is recommended to use the following software to detect. Connect the power adapter when testing the battery, and judge the working state of the battery according to the test results.

1. XP system: use HP Battery Check Manager software to detect the battery, and click "Start" - All Programs "--HP" "-HP Battery Check" after installation.

2. Vista system: install the following two links to check the battery, after installation, click Start - Help & Support - Troubleshooting to run Battery Check.

3. Win7 system: use HP support assistant software to detect the battery. Open the HP Support Assistant software, or click "Start" - All Programs "--HP" "-HP Support Asistant" to select Troubleshooting, Diagnostics.

Click on "Battery, Thermal, and Mechanical", click on "Battery Check", and then check the test results.

4. Win8 system: use HP support assistant software to detect the battery. Open the HP Support Assistant software, click "Battery & Performance" - click "HP Battery Check" - the battery test starts, and then check the test results.

5. The battery test results are as follows:

1) good pass (OK Good): The battery is in good condition and does not need to be replaced.

2) Replace: The battery needs to be replaced. It is recommended to contact the engineer of your local gold service center to help you replace the battery.

3) Calibrate: It is recommended that the user recalibrate the battery and then re-run the tool to detect, if the result of the retest is still "calibrate", the battery may not work properly and needs to be replaced.

4) Unknown: The power adapter is not plugged in, and the power adapter needs to be plugged in.

5) weak (the battery is close to its service life, caused by natural wear and tear, it is recommended to buy a battery).

6) Replace: The battery needs to be replaced.

7) Calibrate: It is recommended that the user recalibrate the battery and then re-run the tool test, if the result of the retest is still "calibrate", the battery may not work properly and needs to be replaced.

8) invalid: The power adapter is not plugged in, and the power adapter needs to be plugged in.

I don't know much about this, but I know that if the phone battery is too hungry, the phone will not be charged, and it must be charged with a universal charge for a while before the phone can be charged.

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

If the mains 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 checks are 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 checks are normal, and basically it can be preliminarily judged that the notebook motherboard is faulty. It is recommended to send the service station for repair.

It is recommended to unplug the battery and power adapter of the machine from the machine, let the machine stand for half an hour to see if the machine can start normally, if it still can't start normally, contact HP's inability center to detect it directly, it may be that there is a hardware failure.

The premise is that the power adapter is plugged in.

No, no laptop will turn on without a battery.

OK. In the case of power, the notebook battery can be used in the case of detachment from the mains power supply, without using the battery, such as removing the battery or the battery is broken, it can be connected to the mains power through the power cord, directly for power supply, and it can also be turned on for use, but in this case, once the power is out, the notebook will also be shut down immediately, the effect is the same as that of a desktop, if you need to continuously carry out documents, graphics, etc., for the sake of safety, it is still recommended to use the battery for work. Under normal circumstances, when the battery level is higher than 90%, the battery will not be charged when the power is turned on, and it is also a protective measure for the battery.

The reasons why the HP laptop won't turn on are as follows:

First of all, try the following operations: remove the battery and power adapter, press and hold the switch button for 30 seconds to discharge the static electricity, wait for about 15 minutes, and then connect the power adapter separately to power on; If it can't be turned on yet, it is the following reasons.

1) The first reason: due to vibration, movement, and poor contact with the memory slot or graphics card slot, resulting in inability to turn on, black screen, solution:

Solution: It is to remove the power supply, open the back cover of the notebook, take out the card slot of the memory, if it is not an independent graphics card soldered to the motherboard, also take out the card slot, align the part of the memory and the gold finger of the graphics card (that is, where there is a copper sheet) and wipe it back and forth with an eraser a few times, blow the ash, and then insert it back, cover the back cover, and it is generally OK to boot up.

2) The second reason: It is that the video memory of the notebook graphics card is soldered, the performance of the main chip is reduced, the graphics card BIOS is disordered, and the control power supply IC is problematic, which will cause the graphics card to fail to work normally, that is, the graphics card is broken, because the graphics card is broken, it will naturally not be able to boot, and the screen will be black.

3) The third reason: the boot circuit of the notebook motherboard is faulty, such as clock, reset, power supply, MOS tube, etc., which may cause failure to turn on, black screen, IO problems, and unable to start the computer, black screen, etc., Solution: Send after-sales or repair shop to repair the motherboard,
