MacBook Pro became completely unresponsive after HDD and Battery change

[eduardsi]

Hello everyone!

Recently I decided to reanimate my MacBook Pro 13" A1278 by changing original Hitachi 320GB HDD to Kinsgton SSDNow V300 120GB and replacing the battery (eBay, Genuine battery according to seller)

After replacing hardware and fresh OS X Lion installation (that took 8 hours), the system became completely unresponsive - after a mouse move it freezes for ~5 seconds, then unfreezes, then you press a button and it freezes again.

- Resetting PRAM didn't help.
- System is unresponsive regardless of power cable connection
- System is unresponsive in recovery mode too

Observations:
- CPU utilisation is around 1-3%
- There is I/O spike when system freezes

Help!

Possibly just the HDD not connected properly, or the cable is a little broken they are very delicate unfortunately and often need replacing.

The 13" are notorious for having shoddy hard drive cables. You probably broke yours during the install.

Thanks for replies guys. Is it possible to diagnose the cable for issues before actually replacing it?

I'm not aware of a way to do that. The part itself isn't all that expensive though on ifixit.com.

Put the original HDD back in, see how that fares?
