HP Notebook 6515b can t get into the system

Looks a lot like the symptoms of poisoning... Anyway, my 6531s was like this once, it was poisoned, try it with system tools to recover?

It is recommended that the landlord press F11 when turning on the machine to detect the system to see what the error ** is and whether it is caused by hardware. Some time ago, my system crashed, and I still have to do a hard drive test when I send it to the gold medal after-sales service. Therefore, it is best for the landlord to conduct a system test first, look at the error**, and understand what causes it.

If it is a hardware problem, you can only find after-sales. If it's a problem with the software, you can try reinstalling the system. But if the landlord is the same as my book, it's a pre-installed genuine system restoration.。

If you only have a C drive, then all the data in your computer will be lost. (This HP's one-click restore is too bt). If you divide the CDE disk (provided that it is not a disk compressed from the C disk), only the things on the C disk are missing.

It's very simple, just reinstall the software. Drivers can be up and down from HP's official website.

If it's a virus, go to the DOS environment to kill the virus, or start the virus from safe mode to try.

Safe mode has a menu option on the boot screen, and only the core programs are launched when entering this mode.

There are many hardware problems, and the common ones are memory and hard disks. It is also possible that the system overheating can also cause problems. I recommend that the landlord turn it on in five minutes.

Boot (not into the system interface) In the DOS environment, there is an option to check the system to see if it is caused by hardware. If the hardware is available, send it for repair immediately.

The kind of one I've encountered is generally caused by a virus. Hardware is often blue screen.

Is it the original system, there may be a system version problem, you change the version to see it, no, it's a hardware problem, and it's directly after-sales.

You can go to the top to find the answer.

It is recommended that the landlord check it out for himself first

If there is a ruler to add or connect external hardware devices, if there are removal of these devices, see if it is solved;

Boot up and press F8 to enter safe mode to use the machine to see if there will be a crash, if there is a format of the hard disk installation system after saving important files to see if it can be solved, if not, you can try to do a full check to kill the virus and close the boot startup items that do not need to be high-level to see if it can solve the circle, if it still can't be solved, you can try to reinstall the operating system;

Whether this fault occurs when the laptop temperature is high, if so, you can try cleaning the machine dust to see if it can be solved.

1. Please recall whether you have done any special operations recently, such as whether you have recently made hardware changes (such as adding new memory), and if so, it is recommended that you restore the previous hardware configuration to try. If you have external devices connected, you can disconnect all external devices and try it.

2. If you have not performed special operations and can operate normally in safe mode with network connection, then you can uninstall the software that you installed before that may cause this problem. If it doesn't work, it is recommended that you disable startup items that don't need to start randomly, so as not to cause problems with some startup items. If you don't have a random startup that you need, you can also disable all startup items and services.

Method: Please click on the start menu, enter msconfig in "Run", open the system configuration, disable all in "Startup Items", and then hide all Microsoft services in "Services", and then disable all of them. You should restart your computer and test if this phenomenon is possible, so that it is not caused by the poor compatibility of some programs.

3. If the problem persists, it is recommended that you test the hard disk and memory in the BIOS to determine whether the hard disk or memory is faulty, the detection method: press F10 to enter the BIOS after booting, then select Diagnostics, and run HDD Self-Test Options to detect the hard disk. You run memory check, which can detect memory.

The whole process takes about 30 to 60 minutes. As a reminder, the battery and power adapter are connected to the power supply at the same time during the test.

1) If there are no errors reported during the detection process, and the results are all passed, then there should be no problem with your hard disk and memory, and it is very likely that there is a problem with the system. It is recommended that you try to save the data and then reinstall the operating system or restore the system.

We hope you find the above reply helpful.

If the driver file is caused by an error, it is recommended that you close all boot items in safe mode, and then reinstall all drivers to check whether it is normal. If you can't, you can only reinstall the system.

1. There are many reasons for the blue screen of the computer, which are generally caused by memory failure (including system memory, video memory, and various caches), compatibility problems with a certain application software (especially remote control software and security protection software), damage to the NTFS volume, or failure of the hardware device.

2. If the machine can no longer enter the system normally after the blue screen, please keep clicking the F8 button when booting (or restarting) to see if you can see "Choose to use the latest correct configuration", if you can see it, please select it and test whether you can enter the system normally. If not, it is recommended to click the F8 button when turning on the computer to see if you can choose to enter the "safe mode", if you can enter the safe mode, you can try to back up the data.

3. If none of the above methods are possible, you can reinstall the system.

We hope you find the above reply helpful.

Regardless of win7 or vista, due to hp's motherboard compatibility, you still can't install other systems well, you really want to install, go to the service department and call the people there to brush the BIOS (there is a certain risk, the brush is broken, and the play is over).

Regarding the problem of the 651 error you described, it is recommended that you first confirm whether the username and password of your machine are correct, if it is correct, you can contact you to check whether there is a problem of arrears in your network, if you rule out the above problems, it is recommended that you can confirm whether the modem has been installed, if it has been installed correctly, you can use the following methods to solve it:

Right-click "Computer" or "My Computer" - select "Management" - select "Services and Applications" - select "Services", find "Remote Access Connection Manager" in the list on the right, and start it.

We hope you find the above reply helpful.

The "Error 651" displayed on broadband Internet access is mainly caused by the failure to connect the user's terminal computer with the Netcom central office equipment, which is generally divided into five situations: "network cable failure", "modem failure", "network card failure", "modem itself setting", and "network operator problem". Here's how to deal with such cases:

1. Please replug the network cable and ** cable and restart the modem test;

2. Please disable the local connection first, and then enable the local connection;

3. Please reinstall the NIC driver;

Fourth, if you use the router, please dismantle, a single computer dial-up test.

Take a look at your network settings and installed drivers to see if they're working properly!

Try a few more times, if it doesn't work, it should not be connected, my computers are wireless, and I don't know much about your situation.

Local connection Disable it and enable it again... Try again. I've been in a similar situation before, but not with HP laptops... Try more, more and more...

Found hope helps.

6515B This business is AMD's CPU, and it generates a lot of heat, but this machine is a relatively solid machine, do you feel that the air outlet is not windy? It's time to clean the fan! If you clean the fan regularly, this kind of business jet is usually one.

Five or six years is still not a big problem.

The heat sink you mentioned is to assist in heat dissipation Auxiliary air intake But if the air outlet is blocked, then no matter how good the air inlet is, it is useless At most, blow the bottom shell cool This machine can see the fan when you take off the keyboard, you just need to clean the fan regularly, and let the maintenance center help you clean it if you are in the warranty.

Recommendations:1. When buying a notebook, the CPU should choose Intel's slightly less heated and stable.

2。Throw away the heat sink、Clean the fan regularly, 6515b。

Clean it up once every six or seven months (depending on the environment in which the machine is used!) Some machines may be cleared once in two or three months).

3.If it's a problem with the north bridge of the motherboard, a small repair shop may be able to fix it for two or three hundred. Of course, the repaired motherboard is not as sturdy as it used to be!

Hope mine can help you out.

6515b, you can clean the ash yourself, there are a few keyboard screws at the bottom, loosen it, slide down a few slides between the switch board and the keyboard on the keyboard side, you can lift the keyboard, open the screen to the maximum, pry up the switch board with a small screwdriver, and you can get off the fan,。。 This machine is like this, or don't repair it, my friend also changed the CPU and motherboard at the same time a long time ago, whether to replace it or not to repair it, that's good. The replacement and repair are guaranteed for three months, but the replacement may cost between 1,000 and 2,000.

It is recommended not to repair it, and if it is broken, buy one. Business is for stability, don't use AMD, HP's business books from other Intel are pretty good.

The 6515B belongs to HP's commercial laptop, which belongs to the low-end one, and the left overheating refers to the overheating of the hard disk, and the CPU fan is on the left side. But this phenomenon of yours is not common in commercial laptops, there are two possibilities, one is excessive dust, and the other is the aging of the machine fan. The pit station says that it is not recommended that you do it, the capital is large and the recycling value is not high.

I've encountered it, and my solution is to use a heat sink, the kind with a fan underneath, which works well, and it seems to have a bit of an effect when removing the battery for external use.
