An experienced friend said, what should I do if the Apple laptop can't be opened with water? First, immediately turn off the power of the notebook computer system and unplug the power cord and battery.

Wipe the liquid on the keyboard and laptop with a clean rag or paper towel.

Move the laptop near the sink and tilt it 90 degrees to pour out the residual liquid in the computer system and keyboard.

Wipe the liquid on the keyboard and machine surface again with a clean rag or paper towel.

Don't blow dry with a hot air blower to avoid overheating and deformation of the shell.

It is suggested to contact the customer service center of notebook manufacturer immediately to arrange inspection and maintenance to avoid sudden failure caused by oxidation and corrosion.

An experienced friend told me, what if Apple 6 suddenly turns black and can't be opened? Press and hold the power for a few seconds, and then slide the red slider down when it appears on the screen. Sometimes the iPhone turns off or doesn't respond, so it can't be turned off in the normal way. You can use forced restart and forced shutdown to get the iPhone back to work. Forced shutdown: press and hold the power (power key/on/off) Home key at the same time, and release the Home key after the black screen appears. A white apple logo will appear within a few seconds after you release the Home button. At this point, do not release the power button until the white Apple Logo disappears and the screen closes. Forced restart: Press and hold the iPhone's power and Home button for several seconds at the same time, and then release it when a white apple appears on the phone screen. After that, the iPhone automatically restarts. 1 iphone4 died too late to boot. What should I do? The easiest trick is to press the HOME button to turn the machine on and off together.

An experienced friend talked about how Samsung's mobile phone suddenly went black and could not be turned on. There are many reasons for the black screen, such as system problems and software conflicts. Any screen damage will be displayed as a black screen.

It is recommended that you try the following methods:

1. If the screen is always black:

Take out the battery and press the power button again to start the machine. If the fault still exists, it is recommended to send the mobile phone to the nearest Samsung service center for testing.

2. If the screen is black sometimes:

1. It is recommended to uninstall the third-party plug-ins running before the black screen.

2. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (Settings-Privacy/Reset-Restore Factory Settings).

If the problem still exists, you still need to bring the purchase invoice, maintenance card and machine to the Samsung service center, and the engineer will check and deal with the machine.

Urgent, buy a laptop. Experienced friends who have used Apple notebooks give some advice. One is macbook, which is suitable for students, family entertainment, word office and other daily applications (low configuration).

One is macbook air portable business class, business mobile. It is the thinnest notebook in the world (not practical, the configuration is too low to meet your requirements).

It has always been a professional macbook pro ~ suitable for design and graphics processing.

Apple computers can now be configured with dual systems.

You didn't say what your budget was! Then I can only recommend the best, 17 inch new model (model MC226), which is the best and highest-equipped Apple laptop at present. I used 17 inch, which is quite good. When I use some design software, it runs smoothly.

Now the new 17 inch processor: 2.8GHz.

4G memory 500G hard disk

8 hours battery life (about 5 hours of actual use)

Two graphics cards: an integrated graphics card (NVIDIA GeForce 9400M GT graphics card) with memory 256 and an independent graphics card (NVIDIA GeForce 9600M GT graphics card) with memory 5 12.

Official price: 19998

17 inch This configuration is the best in Apple notebooks at present, with fast execution speed, but its size is large, which is not conducive to carrying!

If it feels big, there is also a 15 inch (model MB986), which is the same as the 17 inch configuration except that the screen is smaller and lasts for 7 hours (the actual application is about 4 and a half hours).

Official price: 17998

This model is only a little worse than 17 inch in battery and screen size (which can be basically ignored in practical application), but it is moderate in size and convenient to carry!

If the funds are limited, it should be 15 inch (model MB985).

Processor: 2.66GHz Intel C2D

4GB / 320GB

Dual graphics card (NVIDIA GeForce 9400M GT integrated graphics card) 256MB

(NVIDIA GeForce 9600M GT discrete graphics card) 256MB

The battery life is 7 hours (the actual application is about 4.5 hours).

Official price: 15998

This mode has strong cost-effectiveness ratio and fast execution speed, and there is no obvious difference between it and the first two modes in practical application.

There is also one 15 inch (model MC 1 18) and two 13 inches (models MB990 and MB99 1). These three computers are basically the same configuration, with lower processors and smaller hard disks. Not recommended to buy ~

These are official prices, that is, the price of Apple Experience Store in Sanlitun, Beijing. If you buy a student ID card here, it will be about 1200 cheaper (but I don't know the exact amount now). When I bought 17 inch, I bought a discount 1700.

If you buy it from an outside dealer, the price can be reduced by about one or two thousand.

What should an experienced friend say about the slow speed of Apple's mobile phone? Which version of the system are you using? If it is ios7, it will be a bit slow. After all, the hardware of a few years ago can't keep up with the times, just like a computer running xp smoothly, running win7 may not be smooth.

Experienced friends talk about how to weld the loose power interface of notebook. The first point is the disassembly of the notebook. When disassembling the notebook, be sure to remember the position of the screws. It's nothing to screw the short screw onto the long screw. If it is too short, it will be dangerous. If it is too light, it will destroy the appearance of the shell. If it is too heavy, you can screw through the motherboard! So don't use brute force when disassembling! Then remember the removal order of each accessory, if not, write it down with notes, which will make it easier to install!

The second point is welding. In fact, the solder joints of general power ports are relatively large. If you open it and see that it is virtual welding, just add some solder. If it's the power port itself, you have to replace it all, which is a bit troublesome. But you can find it on Taobao! I wonder if you can use a soldering iron. If not, you can also take the motherboard down and take it to the appliance repair office for them to help you weld. Not a few dollars!

Experienced friends talk about how to deal with the leakage of floor heating pipes, and they can only find professional masters to install floor heating. To check the water leakage of floor heating, first of all, conduct pressure test, press the floor heating pipe with a press, wait for half an hour when the pressure is 8- 10 kg, and observe the changes of the pressure gauge. When the floor heating pipe leaks, the pressure will drop sharply in a short time. Next, it is necessary to detect water leakage points, rising surface temperature and water leakage points.

What do experienced friends say about the screen of BenQ projector? 1, the HDMI cable is not plugged tightly; Solution: insert tightly or change lines to insert tightly; 2. If the dmd chip is damaged, go to the service center for repair.

Experienced friends talk about how Apple's 4s mobile phone has insufficient memory to clean up WeChat chat records, uninstall uncommon software, back up photos and videos to a computer or network disk, and then delete the uncommon ones.

Ask an experienced friend to recommend a notebook, and consider ThinkPad E420 (1141-a 31). You can buy it online for 4000 yuan. Main highlights: good heat dissipation, low noise and outstanding configuration at the same price. The game performance is ok, if it is an office worker, it will be perfect.
