Laptop very slow, replaced HDD & HDD cable, what now?
Macbook Pro 13" mid 2012 (MD101 with i5/2.5/500) came in with busted HDD (was not possible to recover data).
Replaced the HDD with a Toshiba 500GB drive 2.5", installed a new system 10.8.
Couple of months later, laptop came back, working very very slow, taking lots of time to react to right-mouse click, double click on video and it hardly plays. Last time I turned it on, the wallpaper was blank and would only "reveal" the wallpaper image where the mouse pointer hovers.
Disk utility did not detect any problem with the HDD.
Tried replacing the HDD cable, and tested the laptop, it started working perfectly well.
Few days later (today), owner called and said laptop was very slow and unresponsive. What should I explore next?
- Boot from external HDD?
- What else can I try? I will have limited time to work on this one since owner will travel tomorrow and I would like to have all options on the table to try them one by one.
Thanks for any help provided!
