Bộ xử lý lõi i5 460m 3M Bộ nhớ cache 2.53 GHz máy tính xách tay máy tính xách tay Bộ xử lý CPU I5-460M

1. Remove the original CPU, clean the dust on the fan and heat sink, and clean up the original silicone grease remaining on the heat sink, especially the hard silicone grease. This is very important!

2. Insert the newly purchased CPU in the correct direction, and apply a layer of silicone grease on the top of the CPU. Do not apply too much, it is ideal to just fill the gap between the top of the CPU and the heat sink. (Take the small sticks of silicone grease in the needle tube as an example, squeeze 2-3 small grids of silicone grease on it)

3. Reinstall the heat sink, first press the heat sink with your fingers and move it up and down, left and right, so that the silicone grease inside spreads out evenly and exhausts the air, and then follow the numerical order marked on the fixing screw on the heat sink (or diagonally) Tighten the screws one by one, and then unscrew one screw each time a few turns. Do not screw one screw to the end at a time, rotate one by one until the balance is fixed.

Only supports PM45 GM45 MCP79 chipset upgrade (ASUS F81SE F83SE Y450 can be used without testing) GL40 chipset does not support the above CPU [emphasizes that Lenovo G450 has two chipsets that must be tested] (Lenovo Y550 Samsung computer Toshiba computer cannot be upgraded, do not shoot)
Must see before installing CPU:

1. Remove the original CPU, clean the dust on the fan and heat sink, and clean up the original silicone grease remaining on the heat sink, especially the hardened silicone grease must be thoroughly cleaned, this is very important!
2. Insert the newly purchased CPU in the correct direction, and apply a layer of silicone grease on the top of the CPU. Don't apply too much, just enough to fill the gap between the top of the CPU and the heatsink. (Take a small piece of silicone grease in a needle tube as an example, it is suitable to squeeze 2-3 small grids of silicone grease)
3. Reinstall the heat sink, first press the heat sink with your fingers and move it up and down, left and right, so that the silicone grease inside is evenly dispersed and the air is exhausted, and then follow the order of numbers marked on the fixing screws on the heat sink (or diagonally) Tighten them one by one, and then unscrew a screw each time a few turns. Do not screw a certain screw to the end at a time, and rotate it one by one until it is fixed and balanced.

Note: After changing the CPU, if you find that the CPU temperature is too high, or the temperature is unstable from high to low, please carefully check the above 3 items, and check whether the quality of the silicone grease is too poor. Most problems can be solved this way.

1. Warranty time:

The time is calculated from the time of receipt of the express delivery. If there is no quality problem, the buyer is responsible for the round-trip freight. If there is a quality problem, we are responsible for the round-trip freight. If there is an incompatibility problem after the buyer and our customer service check the machine configuration information, they shall bear the return and delivery freight respectively. It is recommended to purchase You can choose freight insurance, so you can take "0" risk shopping.

Original official version of PGA: one year replacement, 7 days return

2. Scope of Warranty

The one-year replacement time is limited to blue screen, blurry screen, crash, and unstable factors are within the scope of the warranty. If the CPU is not lit (not displayed, not powered on), it can be returned and exchanged within 7 days. If it is not lit and not powered on, we will not provide warranty or return if it exceeds 7 days after receipt, so please contact our customer service as soon as possible if you have any questions.

Explanation: Why is it only guaranteed for 7 days if it does not light up? Because the notebook CPU is installed and used normally, it will not light up or turn on. Generally, this happens because the chip fracturing radiator is not installed properly, the overclocking burns out, the temperature is too high, and the lightning strikes short circuit. It will be shown that the CPU does not light up and does not turn on, so the light does not light up, and the CPU that does not turn on is only guaranteed for 7 days!

1. Man-made damage (CPU burnout, improper operation, crystal surface damage, physical damage), non-resistance (natural disasters such as lightning strikes) are not guaranteed.

2. The CPU warranty label is torn, and the warranty label is dismantled by someone, etc., no warranty.

Note: After replacing the CPU, if you find that the CPU temperature is too high, or the temperature is high and sometimes low and unstable, please carefully check the above 3 items and check whether the quality of the silicone grease is too bad. Most problems can be solved in this way.
