As mentioned in my previous blog, I mentioned that I was disappointed with the inability of the HP Mini 2140 to enter 'sleep' mode when the lid was closed and also mentioned that there was indeed a unresolved bug (#376793) concerning the HP 2140 and its lid closing detection on UNR 10.04. Intrigued, I decided to test whether this inability affected the previous UNR (version 9.10 codenamed Karmic Kaola). So out went the hard disk from the netbook and in its place I installed a spare blank hard disk that I had kept for such a test.
After installing the UNR 9.10, I updated the OS with the latest updates (after going through the process in getting the Broadcom wireless working as outlined in my older blogs) and then started testing the power management features. I found out that they worked perfectly! The netbook went to sleep when I closed the lid - unlike UNR 10.04. Clearly there was a problem in UNR 10.04 and NOT with the HP netbook.
The question now remains - shall I wipe out UNR 10.04 from the removed hard disk and use UNR 9.10, or continue using the already installed UNR 10.04 but always have to remember to put the netbook to sleep manually? There was one big advantage of using UNR 10.04 - it has Long Term Support (3 years support for the desktop). Battery conservation is a big issue here - if I forget to put the netbook to sleep manually, then there will be problems relating to inability to use the netbook in a remote site. Decisions, decisions, .....
More to come ... stay tuned.
