Is there a problem with the configuration of Y450 30

1.Memory speed and CPU bus are related but there are independent places, the system bus 800, the memory can also work under 1066, DDR3 performance is definitely better than DDR2, there must be a slight difference.

2. Memory has little impact on overall performance, so there is no need to care about these small places.

Abnormal. CPU temperature: Generally more than 70 degrees, you need to pay attention to the fact that your heat dissipation performance is not particularly ideal, and you need to check whether the radiator, CPU fan, silicone, etc. are normal; If it exceeds 90 degrees, there must be a problem with CPU heat dissipation at this time, not only the processing performance is seriously reduced, but also there is a blue screen or automatic shutdown function at any time.

Graphics card temperature: more than 70 degrees, especially when this high temperature occurs as soon as the computer is turned on, be sure to check whether the graphics card fan and heat sink are normal, in addition, the dust left by long-term use is also an important cause of high temperature. If the temperature of the graphics card exceeds 90 degrees, please shut it down immediately to prevent the high temperature from burning the core or video memory of the graphics card.

Motherboard temperature: The northbridge chip is the part that generates the most heat, but the temperature is much lower than that of the CPU and graphics card, generally not exceeding 50 degrees; If the temperature of the motherboard has exceeded 60 degrees, immediately check whether the heatsink of the motherboard is loose, and whether the wiring in the case is messy and the cooling performance of the case is low.

Hard disk temperature: The temperature of the hard disk is generally below 52 degrees, if the heat dissipation performance of the chassis is very poor, the temperature of the hard disk will exceed 58 degrees, which will cause the hard disk to work very unstable, and may lose data at any time, seriously damaging the service life of the hard disk.

Mine is also this one, it turns out that the temperature is also very high, open the back cover, clean the air outlet, and now the temperature is about the same as when I first bought it.

First question: What is the hindrance to redoing the system if it is partitioned?

A: There is no hindrance.

Second question: What does the system mean by backup?

A: In some special cases, the system is damaged and cannot be used, and the backup is to restore the system to the time when it was used before the destruction (provided that you have backed it up).

Question 3: How do I know if I don't have a backup?

Answer: Since the landlord asked, then you must not have backed up... But Y450 generally has a factory backup before leaving the factory (comes with Vista is backed up, but upgrading to win7 is not necessarily available), you can press the small round key on the right of the boot button, if there is a factory backup, it will enter the one-click restore interface, and you can restore the system to the state when you just bought the computer according to the prompts. If you don't have a factory backup, your existing system will be lost.

Question 4: What are the prerequisites for using a recovery disk?

A: If you have a CD... The computer you buy should have a win7 disc wrapped in a white disc bag with a win7 label on the cover.

Question 5: To what extent do you restore your computer after using it?

Answer: If you use the recovery disc to recover, you can restore it to the factory state, which is the state when you first turned on this computer2. If you use a backup file to restore, it will be restored to the state in which you backed it up.

Question 6: Are things like network cards directly included in them?

A: All are included, but not all are up-to-date or dedicated. Therefore, the visual effects, processing power may cause inconvenience in use, it is recommended to upgrade to dedicated and up-to-date after that.

You ask for the specific steps. Since I don't know where you are now, I can't say it explicitly.

If you really want to deal with these on your own, it's best not to operate blindly, but first understand some common sense and terminology in this area, and cooperate with some tutorials to do it.

Of course, you can't, you can find some friends who will or be slaughtered by the after-sales ...

1.Partitioning has no effect on the redo system.

2 System backup refers to compressing and recovering all the data in the system, including the system, the installed software, and some files under the C drive, which is equivalent to saving a copy and placing it under the non-system drive letter for backup. You have your own laptop with a backup, but that backup is not your own, so it may not be what you need.

3、There are no prerequisites,Y450's system recovery,Is to restore to the state of appearance,Including partitions,Data,All to zero,Of course, the drive is still there,It's just that all the changes you made are gone,All the data is gone。

So, it's best to copy out your own important data first, then restore it, repartition it after restoring, and then use ghost as a backup yourself, and then directly restore your own backup later.

To help you analyze it from personal experience, 1: Make sure that your hardware --- wireless network card is normal, (including whether the WLAN in the BIOS is set to enabled when you boot up).

2: Make sure that your wireless network card driver is from the official **, and match the model of your wireless network card, 3: If you have installed the above driver, but the computer's network neighbor does not show the wireless network connection, and the device manager does not show your network card model, that instructions:

There is a conflict between your system and your wireless network card, it is recommended to reinstall a suitable system. By the way, in my own case, before I reinstalled the system (different from the original system), I tried the wireless network card and everything was fine, and after reinstalling, the above problem appeared, which shows that it is the system that causes this problem.

1, Mine is Y450

2. There is a switch about a square on the right side of the computer headset, which can be turned on by turning it to the right.

3. You also need to press the shortcut key, add the F5 key to the FN in the lower left corner of the Y450 notebook keyboard, and then click to turn on the wireless network card.

4. End.

First of all, make sure that there is a wireless network, and whether the wireless settings are turned on in the routing settings.

If it doesn't work, reinstall the network card driver.

If that doesn't work, reinstall the system.

Connect with wifi... Control Panel - Network & Internet - Network & Sharing Center - Connect to the network.
