Thinkpad Edge E530 won't wake up from sleep


I recently purchased a Thinkpad Edge E530 laptop from Lenovo. I think it is great value. I ordered it with the default 2GB RAM and bumped it up to a nice pair of Kingston HyperX 4GB DDR3 RAM, bringing the total up to 8GB. The whole thing costs me only about S$600.

But there was only one problem with the laptop. It wouldn't wake up from sleep or hibernate properly. I have to force power off the machine and boot it up again after sleep. I tried everything. Updating the BIOS. Updating the drivers. Nothing worked. It was frustrating.

After a tedious round of elimination testing, the culprit was finally tracked down to a HDD caddy that I purchased from DealExtreme. This is one of those gadgets that lets you install another harddisk into your space-scarce laptop by using the slot reserved for the optical drive. I use it to add a 120GB SSD drive into the laptop and use it to run certain I/O intensive applications (eg. virtual machines).

As luck would have it, I chanced upon a discussion in NotebookReview.com that talks about this issue on another laptop (but also involves a HDD caddy). I am not particularly knowledgeable about the hardware details, but apparently one of the pins (diagnostic SATA pin) is wrongly connected to ground and needs to be disconnected.


I am not very good with the soldering iron, and anyway the pads are spaced too closely together for my meager soldering skill. So armed with a small tweezer and a sewing needle, I set about trying to destroy the pin in question. Thankfully the pin itself is rather thin, so it didn't take long. A couple of minutes later, I had a clean break.

I put everything back together and powered on the laptop. Taking in a deep breath, I click on "Sleep". Hurray! The red LED on the laptop started to pulse, which indicates it is sleeping. Pressing the power button brought the laptop back to life, just as it was intended to. I couldn't be happier! Thanks to the wonderful folks who shared this piece of knowledge!

  1. A lot of Lenovo Edge users seem to have this problem. I have a E430 and have the no awake from sleep issue. But I don't use the HDD Caddy. The error reports in Windows don't seem to shine much information on what is causing. I get the Kernel power shutdown error from doing a forced shutdown.
    But before that it records nothing to indicate the problem. I myself uninstalled much of the Think Advantage stuff like Power Manager. But that was a while ago. This problem has just started recently. I am perplexed??
