How much power does the IBM Thinkpad T400 consume 30

The silent state (leaving the machine there and doing nothing) is about 10W, the low-load operation (chatting QQ, typing text, etc.) is 12W 15W, and the full-load operation (video rendering, large-scale games, etc.) is about 45W. The discrete display version of the T400 consumes a little more power, adding 2W 20W (12W, 15W 20W, 65W) to the above data.

T400's battery life is very weak, on the one hand, the old platform has high power consumption, on the other hand, the battery capacity is small, and it is generally used for about 3 hours according to low load operation.

Dear Lenovo users, hello! For this question of yours, you can refer to the Lenovo Technology Forum, which has the most complete technical questions, and there are professionals in the forum to answer your questions, and you can also communicate your questions with them.

Power consumption is related to the type of work and workload, the maximum power of the general notebook is 90W, and the minimum is only 1-2W (sleep state), which is more than 30-50W on average.

It depends on your processor and graphics chip model.

It's still very powerful to change the 9-cell battery!

The ThinkPad T450 offers a wide range of options, with a 14-inch screen with a resolution of 1366*768 and 1600*900 (with touch screen), Intel's fifth-generation Core I-series processors inside, support both HDD and SSD storage options, and a starting weight of 4 pounds ().

The specific parameters are as follows:

Hello landlord, it mainly depends on what you buy a thinkpad for. What kind of price can you accept, thinkpad** ranges from 3,000 yuan to 50,000 yuan.

If the landlord is using a commercial business, the computer will generally save some important documents. That ThinkPad T series is really good. Available for purchase.

However, the landlord can also take a look at the ThinkPad X series W series. These series are all very good business notebooks.

If you use it at home, you don't need to buy such a good notebook. It's good to buy a few thousand dollars, and the landlord can take a look at the ThinkPad E series and L series.

There is also Lenovo ThinkPad heat dissipation is very good, and it is considered the best brand in the computer industry.

I make computers, if the landlord has any questions, you can ask me or send me a private message. I'll answer them all. Hope it helps.

I used Lenovo X200 before I felt that this brand was fine, but after switching to T440, it can only be said that Lenovo computers are rubbish. I bought the t440 on March 28, 2015, and found that there was no sound during the use of it, and everything else was normal. 2015, on May 20, I took it to Shenzhen Nanshan Suning store (where I purchased the machine), Suning's after-sales service was restored, and then it has not worked, and there was a problem:

Blue screen, the cursor does not move, they can't reinstall the computer 4 times, and they still can't replace the original system win8 with win7. The end result is that the whole computer can't be turned on and crashes. The computer is dead, Lenovo after-sales service verbally said that there was a problem with the hard disk, and said that there was a problem with the touch keyboard, and in the end, there was no problem with the result.

Then Suning and Lenovo began to argue, saying that it was each other's problem. It's a veritable so-called business computer, and it's not stable at all. Both sides are not replaced, Suning gave the same counter machine to backup, and the blue screen appeared twice a week after a week, but it was normal after a few seconds.

It seems that this machine is unstable and has problems, but we consumers have no way to take them.

ThinkPad T440 is a 14-inch thin and light business laptop launched in November 2013, Intel dual-core quad-core processor, simple appearance with sunken hinges with ultra-narrow screen bezels, integrated bottom design, the body is light, as thin as 21mm, with built-in 3-core + extended 3-cell 6-cell dual battery bridge, optional backlit keyboard.

It's okay, the memory is large, the operation is relatively smooth, and the cost performance is about the same, and the screen is relatively clear,

The performance of the T series is still good; The first digit indicates the screen size: T4 means 14 inches, T5 means 15 inches.

The second digit indicates the generation. At present, the latest is already T480 (with an eighth-generation processor); The T440 has poor performance and uses a fourth-generation processor.

ThinkPad basic workmanship is OK,Generally speaking, if you want to talk about performance, the game book or workstation is better,The performance of the processor now has eight generations or even 9 generations,Generally speaking, the performance of the processor suffix without U is OK such as:i7 8250U,This is a low-voltage version,The performance is basically not good,Then the memory is now the general top configuration is DDR4 2666,Then the graphics card GTX1050TI4G storage is better or more passable, And then there's the hard drive, which is much faster if it has a solid state, and I'm talking about these are the configurations of gaming laptops. If it's a workstation, except that the graphics card is a professional graphics card such as P500 or P600, everything else is similar to a laptop.

Of course, fan heating is an important node, basically speaking, it is necessary to have two fans, three copper tubes or even four copper tubes. The more brutal the fan heat, the thinner the relative handicap.

Very good, what my company gave me is that the high-end is cool.

**Cheap and cost-effective.

The screen is large, there are many functions, and the network speed is fast.

Beautiful appearance and good quality.

Overall good.

If you have any questions, you can continue to ask me.

The 16G SSD in the T450 is used for IRST fast boot. It's just that the laptop turns on in seconds. This is not some accelerator.

This disk will be scrapped soon after it is used for acceleration, and the particle PE is calculated as 3000 thousand times for you to turn off and start up 3000 5000 times. One boot per day is enough for you to use for 10 years. But do the accelerator disk 16g x 3000 PE = 1 year at most and it will be scrapped for you.

Lafeng Chop. It's not for you to install a system. The installation system breaks faster. You can find out what IRST is in Lunchang.

By default, the T450 has IRST Quick Start enabled, and the user does not need to set anything.

After reinstalling the system, you need to turn on IRST, which is the base of Lenovo or Intel official website** IRST driver. Full Name: Intel Rapid Start Technolog Note Not Intel Rapid Storage Technology requires both of these to be installed, but don't get confused.

If you see the SSD disk, don't partition it, if it's divided, delete the partition, and then install IRST and follow the prompts. The system must be loaded inside a tray of 500 g.

This 16G SSD is used to quickly write the data in the memory to the SSD when the laptop is "shut down" and is actually sleeping, and the scratch disk for "booting" is actually quickly writing back from the SSD to the memory when waking up. Don't partition and don't format.

Of course, you can also consider changing this 16G to a larger SSD, and then set aside a 16G space for IRST.

IBM T40 adheres to IBM's consistent style, with a calm and solemn temperament, just like successful people like to choose Mercedes-Benz cars, with the style of a king and a grand style. Equipped with an XGA LCD display that can provide a resolution of 1024x768, the screen has a large viewing angle.

Mature and reliable structure, stable and excellent performance are the biggest buying points of IBM i40. The T40 model is available in other models. The front-side bus speed is 400MHz for fast operation.

T40 uses an Inter 855PM chipset, supports PC2700, and uses DDR266 333 for memory configuration, supporting a maximum of 1GB for a single strip and a maximum of 2GB for the whole machine. Its wireless network card can support three specifications, instead of a single low-end model using a 4500 rpm hard drive, in some high-end models, using a 5400 rpm hard drive, in the more high-end T41 series representative model T41P, using a 7200 rpm high-speed hard drive. The machine generally uses the ATI Mobility Radeon 7500 graphics card and 32M independent video memory, and the sound and color performance is excellent.

The T40 uses a full-size keyboard with large key travel and not small keycaps, making typing very comfortable. Its pointing rod cap has a larger contact area and a more comfortable feel, which is intended to bring users a perfect input experience on a notebook. In addition, the screen of this machine has a large viewing angle and is comfortable to see.

IBM ThinkPad - this is a logo that has made countless people obsessed to the point of madness!! For 13 years, everyone who has "Little Black" will feel lucky and proud. Its stable and generous appearance, excellent and stable performance, comfortable and considerate design, and exquisite and meticulous workmanship have conquered everyone who has used it.

Therefore, ThinkPad notebooks have become synonymous with "reliable" and "professional" in the minds of users, so every work of IBM is the peak that cannot be surpassed by latecomers, so every product of IBM can become a classic. To this day, when we come to experience ThinkPad, we feel not only the convenience and love it brings us, but also the taste and cultural thinking of ThinkPad, and the interpretation of business art.
