It seems that my most popular posts here deal with fixing some common issues with the Lenovo G530 laptop, namely with the screen hinges, as well as the screen flickering. Well, judging by the comments it seems that these have helped people (even though you will probably have to repeat the screen flickering one, as the cable can come lose repeatedly). I am glad they are of use to people; the G530 isn’t the fanciest laptop, but if you can deal with some of these things it certainly gets the job done.
I am having a particular problem with this machine, though, that I have not been able to sort out. It deals with suspending to RAM, or I should say, the inability to do so. What is supposed to happen is that I activate suspend, and the machine almost completely shuts off save for a blinking, blue LED. Opening the lid then resumes the machine almost instantly, bringing me back to where I was. (Yes, I’m sure most of you know what suspending to RAM is, but I’m just trying to be complete.) However, when I actually try to do this, the machine shuts off, instantly. No flashing light, no shutdown sequence, it just turns off as if I removed power and/or battery. Turning it on again makes it boot up as if I had opted to reboot. After a while I got used to just turning the machine off when I didn’t need it, but this is kind of annoying, and I would like to fix it.
Now, first things first. As you can probably tell from this site I am a GNU/Linux user, and do in fact run Ubuntu on this laptop. In fact, overall it runs well. I bring this up because of many suspend issues which have plagued many of the distros, however for about the first year of having this laptop suspend to RAM worked beautifully. (Hibernate did and still does, but suspend is more convenient.) But to verify this I tried installing Windows XP (along with the hardware-specific drivers supplied by Lenovo on their site), but encountered the same behavior. Same with other distributions.
Next, I figured on a lark that maybe this would have something to do with the battery, which when I first noticed this behavior was on its last leg (ie, 20 minutes of power). I replaced the battery, but this did not help anything. I tired looking in the BIOS, but couldn’t find anything that suggested a problem. I tried updating the BIOS, but this didn’t work either. I even tried alternating the RAM sticks, as well as using only one at a time. (It is suspend to RAM, so I figured there might be something there.)
So, how about it, anyone else seen this sort of thing before, shutting down cold instead of suspending? Maybe not even with this particular laptop? Any ideas, thoughts, something I may have overlooked? I will try to make something of an effort to look into this again myself, probably starting with running memtest86 on the machine (something which I did not do, and may reveal something more about the memory). But, I would appreciate any input. And if I come to a solution, I will of course do my best to report it here, with a nice pictorial guide if applicable.
