The HPDV2000 has a black screen after booting up, and there is a long and two short beep sound What

My HP is dv2012tx

It's been 2 and a half years, and there have been one long and two short alarms.

Obviously, it's a problem with the graphics card.

The graphics card is broken first of all because of the quality of the hp.

Graphics card chip virtual soldering!

Heavy-pressing the chip is just using a machine to melt the solder off the chip.

Re-solder! There is nothing wrong with the chip!

And the laptop's graphics card and motherboard are on the same board.

It is impossible to disassemble and repair, and it is impossible to just change the graphics card.

As for one long and two short alarms, the V3000 and DV2000 series of HP machines have them!

It's a design flaw! But people don't admit it!

If you have ever broken it during the warranty period, take it to HP for repair.

People will only give you a repaired board, but they claim to have replaced you with a new board.

If you want to repair it, it's best to go to the computer city to repair it, and any one of them will repair the notebook.

And you can stand on the sidelines and watch while you're repairing!

**No more than 150

The ** of 300 is claimed to give you a new chip, saying that one long and two short is that the graphics card chip is broken.

But in fact, it is just a design flaw, and it is just a virtual weld. The chip will indeed change for you.

But next time someone else fixes the same problem, he will give your chip to someone else to replace... Your warm-up method can be useful temporarily.

Turn on the machine and leave it alone, wait for 10 minutes for the machine to heat up, and press the shutdown button to shut down.

Then turn on the machine, there is a 10% chance that it can be opened, and it can be used normally after opening without any effect.

But the problem is obvious, one day, you will not be able to start a complete virtual welding.

Ay! Good luck!

PS: HP 800 completely denies the problem of the design flaw of the graphics card, but anyone who repairs the laptop knows that this flaw exists. After all, relying on the hot sales of the V3000 and DV2000 series, the existence of this defect has indeed brought a lot of money to those who repair notebooks.

Unplug the memory and plug it back in.

It is recommended that you call HP's dedicated after-sales technical support**800-810-3888, remember to dial with a fixed **, and operate according to his voice prompts,,, good luck.

It could be a display or graphics card issue, but it's not that the graphics card is loose, because the laptop graphics card is dynamic, not separate.

I think most of your motherboard burned down, this one is good, but the heat dissipation is too poor, and I burned it once.

The HP warranty period is two years after the date on your invoice, and you can go to the gold medal to fix it. If it's out of bail, the last time I chatted with the engineers at the gold medal they told me that a motherboard costs about 3000, and I don't know if it's real or not.

Message me with questions

I'm the same model as you! It's been the same situation as you lately! A friend said that the memory module was loose, and I have reinserted it n times!

Still useless !! My notebook is out of warranty! Also by the way, please consult the master reply!

Hurry! Thank you.

The graphics card is welded, if you don't get it to the repair station to replace the motherboard, if you get it out of warranty, take it to the place where you repair the book, and repair it, the cost is about 260 yuan.

This is a common problem of HP, and the V2000 to V3000 series all love this problem.

HP after-sales technical support**800-810-3888 toll-free**. Monday to Friday from 10 a.m. to 5 p.m.

If you're an integrated graphics card, there's no problem with the motherboard, or the memory module isn't plugged in properly or it's time to clean it.

Suggestion: Take it to a computer hospital.

Don't be careful, there is a problem with the system, you can redo the system, it really can't work, you have to check the motherboard.

The phenomenon that occurs in the laptop may be related to the operation of the hardware, and later you try to operate the electrostatic discharge step, and the static accumulation may have a similar effect. It is recommended that you remove the laptop and connect it to other external devices (if there is a built-in optical drive, remove the optical disc in the optical drive), if other hardware has been added to the notebook, such as memory, also need to be removed, remove the battery and external power supply, completely power off, stand for half an hour to release static electricity, and then connect the power supply to power on to observe whether it can resume normal display and use.

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.

rt and then the lights are on, but the screen is not showing and the mouse lights are on.

Landlord,My DV2012 has just had this problem.,One long and two short is that the BIOS detects that there is a problem with the graphics card or monitor and reports an error.。 It should be a problem with the graphics card, because HP notebooks generally have design flaws that cause problems with the graphics card, and there are many users in the DV2000 series who have this problem on their computers, and it is useless for you to try repeatedly, and it must be repaired.

The reason for the problem is this, the CPU and GPU are designed too close to each other when the HP notebook is designed, and the fan is used together to dissipate heat, but the air inlet of the fan is too small, only 1 3 of the fan, so the CPU and GPU are both components that generate great heat, so the temperature is too high when running large programs. Moreover, there is a 2mm gap between HP's GPU and the heat dissipation component, which is connected with silicone, but due to the high temperature for a long time, it will cause the silicone to harden over time, resulting in the heat of the GPU being unable to transfer to the heat dissipation component, resulting in a very high temperature of the GPU, which leads to either virtual soldering between the GPU and the motherboard, or it is directly burned out.

Now if you go to the gold medal maintenance, you will generally be asked to replace the motherboard, if it is within the warranty period, then replace it, if the warranty period is exceeded, it will be more expensive to replace the motherboard, you can also try to weld, but it is easy to have problems after a period of time after welding. If you change to a new motherboard, you can't tell when it hangs up again, this is a design problem, and there is no way to solve it now. There is a copycat method on the Internet to improve heat dissipation is to change the silica gel mentioned above to silver (or use a small amount of silicone to connect with the graphics card), but this requires a certain amount of hands-on ability, and the silver sheet must not fall off the motherboard, because the silver sheet conducts electricity, if it accidentally falls on the motherboard when it is powered on, then the motherboard will burn off.

I bought this computer and I can only use it for a while.,There's no way.,If you use it for a long time.,Change the computer.,Don't buy HP.。

In addition, HP also has some computers that use NV problem graphics cards, and the problems of these graphics cards can rise dramatically at some point, thus exacerbating the problems I mentioned above.

This is the result of my research on a lot of information, I hope it will be useful to you.

My advice is, if it's under insurance, then go for a change of motherboard; If it's past the deadline, if you have the money and you like the computer, then go for a motherboard, if not, try soldering first. If the computer has been used for a long time, then just change the computer, don't buy HP, because HP is not only this model has this problem.

Dear users, the causes of the black screen of the computer and the solutions:

Black screen caused by software.

1. Sometimes after installing some software or hardware drivers, you find that after restarting, the computer can't enter the system, and the screen has been black, which is the black screen of the notebook caused by the software. If the screen is blacked out due to software, take Windows as an example, you can restart the machine and press the F8 key a few more times when turning on the computer to bring up the system's boot options menu.

2. After the system boot options menu comes out, select Enter Safe Mode. If you can enter the safe mode normally, you can delete the software or driver installed before the black screen in the safe mode. Then restart the machine and see if the laptop can fix the black screen issue.

Hardware-induced laptop black screen.

1. On the laptop, there is a sensor switch, when the screen is closed, the display screen will automatically turn off, so as to save power consumption. Some notebooks are mechanically touched, such as when the screen is closed, it will touch it, like a beginning to disconnect the power of the display.

2. There are many reasons for the black screen caused by hardware. Let's talk about the cause of static electricity first, sometimes static electricity will cause the circuit of the notebook motherboard to be abnormal, resulting in no reaction on the screen after the power is turned on. You can try to turn off the battery and power of the laptop, and then press the power of the laptop a few more times to let the machine release the static electricity.

Then connect the power supply, turn it on, and see if it can solve the fault.

3. The memory is loose or the memory has a hardware failure.

4. The LCD screen part of the notebook is faulty. There are some notebooks that are a little older, and this may be the case.

5. The hardware failure of the graphics card, the graphics card is responsible for the source of all the display output of the computer, so it has a problem, and there is no display on the screen. If the graphics card is broken, you can't solve it yourself, and you can only find the computer's after-sales solution.

You can buy a mobile phone in the Anhui Telecom online business hall, and the network hall will give a high phone bill for the contract machine, and you can buy the machine for 0 yuan, which is very discounted, and many brands of 4G models are fully listed!

One long and two short is the graphics card alarm,This machine is the machine of the graphics card door,This you have to look at the chip date,If it is a graphics card chip 09 years ago, it is the graphics card door,You didn't change the improved graphics card last year,This must be replaced with a real improved graphics card and transform the heat dissipation。 This black screen, one long and two short, blurred screen, crash, etc., are all different manifestations of problems with the graphics card chip.

DIY repair how do you repair, the core heating is not, this operation has certain requirements for temperature, in fact, the tin dot inside is broken, specifically the tin in the chip or the tin dot fracture between the chip and the motherboard has to use an X-ray machine, most of the past tests are the solder joint fracture on the motherboard, generally between 3 and 10.
