Dell Latitude E6400: Hibernate not working (Windows XP)


Dell Latitude E6400 laptopAt work, my employer provided me with a Dell Latitude E6400 laptop. While I do actually like the machine in general (despite it’s running Windows most of the time…), it had one very disturbing issue: from the very first day since I got it, the laptop suffered from Windows insomnia.

I was neither able to put it into standby nor hibernation mode successfully. When I tried to do so, I was logged out of Windows and greeted with the “Preparing to Standby/Hibernate…” dialog that just never disappeared.

It turned out I was not the only one experiencing that problem. Last week, I finally got the hint that led to the solution: Another Dell user found out that reverting the Dell Webcam driver to the previous version solved the issue. I can confirm: this worked for me, too. Finally!

Update: I just learned that there are users who have the same problem with the Dell Latitude E6500 laptop, although they are trying other approaches to solve the problem.

Update 2: I was also experiencing a problem with the CPU running at ~100 Mhz, so my E6400 was replaced after 3 days of usage way back in April this year. It seems that Dell is now admitting the issue: they released a BIOS update to solve that strange behavior.

Setting up hibernate mode on the MacBook Pro


Fred sent me a link on how to set up Hibernate with the MacBook Pro (MBP).

Usually I shut down my MBP when I go to sleep because I don’t really like the idea of having it connected to the power supply while I sleep after my battery died under very suspicious circumstances. By default the MBP goes to sleep mode when you close the lid (suspend to RAM), but if it’s not connected to a power supply that obviously consumes some energy from the battery.

When I changed its sleep habits to hibernatemode 1, the MBP does suspend to disk (it saves the content of the memory to the hard disk). It needs a little more time to wake up (compared to suspend to RAM), but now I can sleep without worrying about exploding batteries and return to where I left my work the next morning.
