Let s talk about buying HP DV2803 or V3803

The DV2803 dissipates heat better than the V3803.

The DV series and the V series use different molds, and many articles on the Internet say that the heat dissipation of the V3000 series molds is not very good.

But the V3000 series is the best value for money among HP laptops.

Personally, I feel that it is better to buy DV2803, and heat dissipation is very important. I use the Thinkpad, and the keyboard doesn't feel hot for a day after turning it on. The heat dissipation is easy to use, and the performance is stable.

To correct the statement of the two people upstairs, HP's after-sales service is very good. In China, it is just a little inferior to Lenovo. HP is a big brand in the world, and Lenovo only has a lot of after-sales service points in China, but it is impossible to have as many after-sales service points in other countries as in China.

Agree with the upstairs, I use at least 10 pieces of HP digital electronic products, after-sales service is polite to you embarrassed.

The price point of the DV series is slightly higher, but the heat dissipation is slightly more prominent than that of the V3000 series.

In fact, there is basically no difference.

HP looks at the configuration and buys OK, basically don't care too much about performance, the premise is to buy the genuine, don't buy refurbished.

It is recommended not to buy HP's, it is troublesome to use and maintain.

Oh, I'm using this one, too! I bought it in March! Not bad! The 6650 I bought, just a bag, a mouse! The chipset is about the same!

This one is good.

You can also take a look at the HP 6520-262.

What are you for?

I don't know if your machine is the same as mine Mine is the same as your model It's when you turn on the machine or when it wants to call it, you hear the fan have an undulating sound It means that the sound of a turn is very strong and then impotence is strong and then continues to be strong and continues to be impotence But after a while, it will be calm again In general, this machine is still relatively quiet By the way, after I appeared this voice, I met the main version and broke it to the gold medal and changed the main version, and then there was no sound I want to do more is the dust inside Clean it up more!

The sound is generally emitted by the hard disk... If there is no blue screen problem. The explanation is not a problem with the hard disk...

It is normal for the hard drive to have a sound during operation.

It can't be said that it is HP's.

It can only be said that it is Compaq, a subsidiary of HP.

Seriously, the Compaq machine is not very impressed by many people.

However, in my personal opinion, the performance of the Compaq machine is still stable, and it is not easy to crash.

According to you, it could be caused by your graphics card overheating.

It's been a year.

If it is a place with very little dust.

Then you can clean up the machine for a year.

If the dust is particularly heavy.

Then you will have to clean it up in half a year at most.

or it will cause the temperature to be too high.

You feel yourself capable of words.

You can disassemble the machine by yourself.

Clean up the dust. The temperature can drop by at least fifteen degrees after cleaning.

In addition, the V3000's graphics card chip is padd with a fast thermal conductive silicone between the heat sinks, which you can replace with copper sheets.

or aluminum sheets. Length 1 cm.

Width 1 cm. Bigger is better.

If you put it on.

The temperature drops by at least 35 degrees.

Good luck.

There is a charge for cleaning the fan, and I will help you clean it up in Beijing.

It's very easy to clean up the dust, you don't have to go that far, find a computer repair company near your home, they should have an air pump there, watch how they disassemble the parts, and then watch them blow the soot, that's it! The computer should be blown at least 2 times a year so that the heat dissipation will be better.

In fact, I almost bought it last week, and it was quite cost-effective.

However, I went to the store and decided not to buy it, because it was too hot, and the heat dissipation was not as bad as the legend on the Internet.

In the end, I bought an ASUS A8H575SR and it felt good.

Personally, I like ASUS and Lenovo, and I wanted to choose one between HPV3803, ASUS A8H575SR and Lenovo F41AT5550, hehe.

It doesn't matter what others say, the most important thing is to go to the Pacific Ocean or Zhongguancun to learn more, and then go to the store to watch.

Well, this machine was a very cost-effective machine back then, but unfortunately it was later revealed that it was a graphics card door machine. This is the 8400 graphics card door machine. Many machines have problems such as blurred screen, black screen, and crash after two or three years of use, and this problem can only be solved by replacing the improved 12-year graphics card chip and transforming the heat dissipation.

I guess I regretted buying this back then. If you want to buy a second-hand machine, it is recommended to stay away as well.

This machine is not bad, but it has been discontinued! Upstairs said that because its hard drive and CPU are on the left hand side, the temperature of the left palm rest is a bit high. The upgraded version is V3907TX, and compared to 3803, the main thing is that the CPU has been upgraded from 5550 ( to 5850 (memory up to 2G

That's it. 6500 can be taken down!

If you want to use it, you have to put up with the high temperature of the left palm rest.

Incompatible with imperfect installation.

At present: 1. Whether the fan is constantly spinning non-stop.

2. Whether the built-in wireless network card can be used normally.

3. Whether the touchpad can be used normally.

Fourth, the problem of the speaker and headphones ringing at the same time.

The fan can be modified by installing software. The rest is the problem.

The heat dissipation is improvised, and the V3000 is like that.

Poor heat dissipation caused by overheating of the graphics card and damage to the virtual welding, send it for repair to solve it, I will help you test it for free in Beijing, and it can be repaired on the same day.

Is this laptop of yours an NVIDIA graphics card?

NV's notebook graphics card had a very serious quality problem in 2008.

If the warranty period is not over, you can go to customer service for repair.

If it's over, it's miserable...
