HP s DV2305 boots on with a black screen and has a long and two short alarms

Upstairs, the laptop graphics card can't be removed and installed on another machine.

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 wait for the next time someone else has the same problem to fix, 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.

As for why the preheating you asked works...

The theory is probably because of the fact that the melting point of tin itself is relatively low, and the current itself has suction. As long as there is a little contact, it is connected.

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

Ay! Good luck! Be careful js

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.

Graphics card issues. Check the cable and plug the graphics card into another machine to try it out.

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.

Disassemble the device, reseat the memory module, and try to reinstall it with an eraser.

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.
