Thread: Survey: Startup times and methods

The range between a fully charged and fully discharged lead acid battery is somewhere between 0.8V and 1.0V depending on the type of battery, and an automotive starting battery should *never* be drained more than 50%.

I *strongly* encourage anyone using an auto-shutoff controller to read this FAQ: http://www.uuhome.de/william.darden/carfaq.htm

The way that most battery shutoff controllers are configured is to save just enough juice to start the engine in an emergency and draining your battery to this level on a regular basis will dramatically reduce it's lifespan.

Here's a fairly good explaination:

Just as an aside to all this, I'm not tryink to knock sleep mode. Quite the contrary, I think it is the way to go for car computer applications.

basically anything under 1 amp is fine.

A compustar alarm takes 200ma while 'idle'.

Surely more folks can contribute than this. Please help. Thank you.

1. Hardware Configuration
* PC config - Epia M1000, 512M, 12G laptop drive ( ?? have to check RPM)
* startup controller - M1ATX, 5 sec startup delay
* tweaks/configs - BIOS set to quickboot
2. Software Configuration
* operating system - Windows XP Pro
* front end & component - Frodoplayer
* tweaks/configs - some services disabled, minlogon and regedits tweaks
3. Startup Stratgey
* type of startup - cold boot
* no special startup tricks, ignition wired directly to M1ATX
4. Startup time, broken down by component of possible
* startup controller delay - ?
* BIOS delay - 3-4 secs
* HDD delay - 45 secs
* total time from startup initiation (ignition or remote entry) until music comes from speakers - about 50 secs
5. Subjective information
* On a scale of 1 (not important) to 10 (very important) how important is a quick startup time? - 10
* On a scale of 1 (not satisfied) to 10 (very satisfied) how do you feel about the startup time of your system? - 3
* On a scale of 1 (not important) to 10 (very important) rate how interested you are in improving your startup time. - 10
6. Any other configs, notes or comments that don't fall into any of the categories above.
* I can update the information on the things areas I left with a ?? but it seems like I can't speed up the boot time to play music more the 90 seconds. The only thing that I have not used yet is the nlite program. Could this actually cut maybe 30 seconds from my boot-tiime? Am I doing something wrong? Is it Frodoplayer that's killing my time?
