Being very happy with pdaXrom on my 860 I wanted to work(!) with it on the
road. Well. BUMMER. I had it suspended in the evening and it would not wake up, not even boot again in the morning. After some investigation I found the battery was comlpetely drained. Some experimentation showed, that my Z sucked power while sleeping. Over night it would return to 100%, reported in /proc/apm. Only a few hours later, disconneted from the AC plug but suspended, it was down to 45 %. Cacko and Angstrom did not behave that way. Is this a known issue? Can I provide further info for someone 'who just knows'? detlef 860er, pdaXrom r197 sp8, 1 SD card, 1 CF card, no wifi connected. |

Some numbers: Before I went to bed > cat /proc/apm 1.13 1.2 0x02 0x00 0x00 0x01 95% -1 suspend Z In the morning > cat /proc/apm 1.13 1.2 0x02 0x00 0x02 0x04 5% -1 plug in AC; wait about 10 MINUTES ?! > cat /proc/apm 1.13 1.2 0x02 0x01 0x03 0x08 100% -1 Hmm. What do these numbers mean? Is there a serious bug in apm? Or do these numbers indicate a dying battery? Any hints appreciated detlef |

QUOTE(ecc_hy @ Dec 2 2007, 01:33 PM) Same problem in my C1000. That is why I back to 1.1 beta3 I have noticed a similar thing, but only If I suspend while powered from the mains and then disconnect the mains. If I suspend while not being powered from the mains then it seems to suspend fine and doesn't eat the battery. |
