Intro:
Agar aapka MacBook slow chal raha hai, apps hang karte hain ya multitasking mein dikkat hoti hai, toh RAM upgrade karke performance better ho sakta hai. Ye guide aapko step-by-step batayegi kaise MacBook Pro Mid-2009 model mein RAM replace karte hain.

🧰 Tools You’ll Need:

  • Phillips #00 screwdriver

  • New RAM modules (DDR3 PC3-8500 1066 MHz SO-DIMM, max 8GB)

⚠️ Safety First:

  • MacBook ko shutdown karo aur power adapter unplug karo.

  • Static-free surface pe kaam karo.

  • RAM ko handle karte waqt gold pins ko touch mat karo.

📋 Step-by-Step Instructions:

🔹 Step 1: Bottom Case Remove Karo

  • MacBook ko ulta rakho.

  • Neeche ke 10 screws remove karo using Phillips screwdriver.

    • 3 screws long hote hain (hinge side wale) — unhe alag rakh lo.

  • Bottom cover ko gently lift karo aur side mein rakh do.

🔹 Step 2: RAM Locate Karo

  • Battery ke upar ek metal bracket ke neeche RAM modules lage hote hain.

  • Aapko 2 RAM slots dikhenge.

🔹 Step 3: Old RAM Ko Nikaalo

  • RAM module ke dono sides mein metal clips hote hain — unhe gently outward press karo.

  • RAM thoda upar ki taraf pop-out ho jaayega.

  • Usse 45-degree angle pe pakad kar seedha bahar kheench lo.

📌 Same process second RAM module ke liye repeat karo (agar 2 lage ho).

🔹 Step 4: New RAM Install Karo

  • Naya RAM module ko 45-degree angle pe RAM slot mein insert karo.

  • Firmly push karo jab tak gold connectors andar chhup jaayein.

  • Phir RAM ko neeche press karo jab tak clips click karke lock na ho jaayein.

📌 Second slot mein bhi same tarike se install karo.

🔹 Step 5: Bottom Case Wapas Lagao

  • Lower case ko MacBook ke upar align karo.

  • 10 screws (3 long, 7 short) ko sahi order mein tighten karo.

✅ Final Check:

  • MacBook ko on karo.

  • Press Option (⌥) key during startup (optional) to test hardware.

  • Mac boot hone ke baad, Apple menu > About This Mac open karo.

  • Check karo new RAM total size show ho raha hai ya nahi (e.g., 8 GB).

💡 Tips:

  • Is MacBook mein max 8GB RAM supported hai (2 x 4GB).

  • RAM lagate waqt force mat lagao — sahi angle aur alignment zaroori hai.

  • Agar Mac boot nahi ho raha, toh RAM properly seated hai ya nahi check karo.
