Do you spend more and more time on waiting for the response of your MacBook?
As long as laptop exists, “running too slow” seems to be an everlasting topic for the users. MacBook, as one of the mainstream laptops, has also encountered this issue.
If you are a regular Macbook user and just browse some websites, you may feel satisfied with 4GB or even 2GB of RAM installed. If you are a power user who always processes with large softwares like video editing, image editing etc., or you are a crazy gamer who is roaring “Glory To The Sin’Dorei!”, you may consider upgrading as much RAM as you can. This is a common problem for common people with MacBook in this information explosion era – not to mention people who have an old-fashioned MacBook with one foot in the grave. Compared with a new purchase, RAM upgrading could be a nice choice to boost your Mac’s speed since it is more cost-effective.
However, for some MacBooks launched in recent years, their RAM chips were designed to be soldered on the logic board. That’s why there were many How-To geeks offering tutorials of upgrading or replacing SSD, but almost no one involving the upgrading of RAM. Don’t be discouraged if you are reading this right now. REWA never lets you down and always has a repair solution for you. Here are detailed steps for upgrading RAM in the MacBook Air – a quick and inexpensive way to improve your MacBook’s performance.
1. Memory Checking
Check the memory. It displays 4GB.
2. MacBook Disassembling
Remove the lower case, then detach the battery and IO board flex. After that, detach the fan, heat sink and WiFi antenna lightly. After the flex cables being disconnected, detach the motherboard. Remove the SSD, wireless network module, QR code and bar code on the logic board.
3. RAM Chips Removing
Heat up the sealing adhesive around the RAM chips with hot air gun, then remove all the sealing adhesive. Apply some BGA paste flux around the RAM chip and blow it with hot air gun to take it down. Remove the rest three chips in the same way.
After the bonding pads being flatted by tin added soldering iron, clean the bonding pads with alcohol applied anti-static wiper.
5. RAM chips soldering
Blow the bonding pads with hot air gun and apply some BGA paste flux to it, then align the RAM chip to the bonding pad by tweezers. Blow and solder it with hot air gun. The rest three chips can be processed in the same way.
6. Resistance Removing and Replacing
Remove the 10K resistance R2051. Detach a 100K resistance from a broken motherboard and solder it to the R1636. Test both ends of the resistance with multimeter to check if there is short circuit or missing solder.
7. Change BIOS and Restore
The RAM of MacBook is bound with BIOS, so we need to change the BIOS and restore.
8. Installing and Testing
After installing, power up the Mac and check your “About this Mac” to make sure the memory is upgraded and recognized.
1. Size and brand of RAM chips can not be mixed.
2. Excessive temperature will damage the RAM chips and logic board.
Here is a tutorial video for the upgrading of MacBook Air, explaining and demonstrating the detailed operations of how to replace the RAM chips soldered on the logic board.
