Step 11: Reassembly

  • Naye cable ko exact jagah place karo.

  • Saare screws wapas tighten karo in reverse order.

  • Fir battery connector, bottom panel aur screws sab wapas lagao.

Final Check

  • Hard drive detect ho raha hai ya nahi check karo. Agar issue fix hogaya ho, toh performance aur reliability dono improve ho gaya hoga.

Tips & Notes

  • Mid 2010 models mein hard drive cable damage common issue hai—especially SSD se sensitive contact hota hai.

  • Cable ko pull ya bend karna avoid karo—naya cable install karte waqt alignment aur seating perfectly tight honi chahiye.

  • Agar phir bhi drive detect nahi hota, cable ke connector aur soldering points double-check karo.
