New utility to save battery - Page 2

I dont really rent those kind of movies, so I didnt know

Re: Correction...

Nice to hear you have it working, and that it gave some extra battery time for you!

I only takes requests if I find it interesting and useful, and maybe then, if you also send me money.
Do you mean audio playing controls? Why the hell would someone wants to use these? Just put your mp3-packed cd in your sager and use winamp.

Sorry if I got irritated for a moment there. Maybe my internal english/swedish translator misinterpreted the whole thing a little. Its also late in the evening here

I'm always open for suggestions for what people might consider be very useful utilities. If it sounds interesting and gives me the reward of getting to know and learn something new, and I have the time of course then maybe I'll do it.

The temperature monitor was a prime candidate in every aspect because many/everyone thought it was impossible and I learned a lot while doing it.

Ouch! Thats no small utilites we are talking about here, is it ok if a have them done by the end of this week?

Just kidding, of course. Its interesting to hear what people really wants so I will try to elaborate a bit. The IRQ thing in windows xp is an ACPI thing, so you can actually disable it by installing xp in non-ACPI mode, then you are free to alter the hardware settings on your own. The drawback is that you lose the Power Management functions in ACPI as well, such as stand by, hibernation and so on. I have read some info on the topic and regarding to the PCI standard all devices are obliged to be able to have an shared IRQ, as opposed to the old ISA-standard there sharing was not possible. I even read some very interesting information from a guy who worked on microsoft developing exactly this part of the OS, and he was not very pleased with all things, he made a better algoritm for IRQ-assigment but it wasnt implemented due to they not wanted to have to betatest other parts again a think it was. Anyway, the irq sharing seems to work ok, but I for sure still would like to have my graphics card on its own irq. And also, I have a computer which dont know its have a modem, and I suspect it may be related to irq-sharing in some way. I have yet to investigate into this, I'm waiting for another one to enable HT on the 5660 to see if the problem is there also. 3 people, i think, have flashed their bioses with my bios. But noone have enabled HT yet. Actually I was reading some info today and stumbled upon how to change IRQ, XP doesnt let you because it cannot guarantee it to work all the time, but I'm willing to try of course. Tweaking my bios gave me nerves of steel. You have to wait and see, maybe I will do some experimenting.

Yes, not supporting HT really sound like a deliberately broken feature, and I hate when that happens. Thats why I was so decisive to enable HT on my 5660, I turned out to be partly right, there exists no hardware limitations in order to use HT, but there may be cooling issues, but it seems ok in my case. Anyway, me personally like XP more than win2K, even though I used 2K for a long time I'm not using it anymore so I wouldnt mess with that.
Also, we live in a reality, and if MS saves money by not supporting HT on win2K hopefully they will spend them on make XP better instead.

Finally you are head on My next little project as I already have thought of, will be to investigate the embedded controller even further, and see what can be done about adjust the fan speeds and the voltage. Lowering the voltage when downclocking the cpu shouldnt be any problem, and that would consume less battery and produce less heat. My fans are on all the time, I dont know about yours. But I think there will be a threshold when I manage to get down the cpu temp so the fans dont have to work all the time, the battery will last way longer.

At the moment, my work schedule is really full, so I wouldnt hold my breath if I was you, but you have to wait and see.

When you reenable acpiec.sys the system goes back to normal, you will absolutely NOT lose any functionality permanently. When acpiec.sys is disabled you cant hibernate and stand by, also the automatic cpu downthrottling because of heat gets disabled. This I actually prefer because now you can measure how hot your lappy really gets without beeing fooled by the downthrottling. I recommend you to read the thread "5660 HT/video chipset", where me and others have posted our results and discusses them. It would be great if you could post your results so me and others can compare, good luck!

A small clarification, if its only the Battery Saver you are talking about then you dont have to disable acpiec.sys, its only if you want to use the temperature monitor.

Myrkat, it seems like there are two reasons why some people dont get it to work. Some are getting an access violation when starting the program and some gets weird readings like you. This isnt connected to Sager model, because on two models that I know of, 5680 and 8890, some gets it to work and some dont. It may be related to keyboard bios version, and that would make sense, but in one case I know of, two people have the same version or so they say, and one are getting weird readings. Still, as far as I can tell from reading the posts on the forum, most people are getting it to work. I wont put any more effort in finding the reason for this, because the solution is ugly anyway, because you have to disable ACPIEC.SYS. I will instead put my efforts in the new upcoming utility that includes cpu temp monitoring, CPU throttling among other things like fan-control. I'm lagging behind on the development of that utility but I will get it finished as soon as I find time for it. This new utility wont have need for disabling ACPIEC.SYS.

BTW, I noticed you made this thread sticky, nice.

Finally, as readers of the forums now know, it is possible to overclock the 5680 and 8890. I'm sure that they also can be underclocked to 50% using a 100 MHz bus speed instead of 200. Because this is _real_ downclocking, and not throttling, this probably would save a lot of battery. If I had a 5680 I would have done a utility for that combined with the throttling.

Myrkat, I think your system bios is made by Phoenix and the EC firmware (keyboard bios) is made by Insyde. This is how it is on all Clevos I know of, including mine. Check this link, Insyde is also a taiwanese company.

You dont have to disable ACPIEC.SYS to run the battery saver, thats only necessary when you want to use the temp monitor. You still have to install the device driver, though.

Because the CPU is throttled, not downclocked, the only way to make sure its working is to bench. I recommend to install Sisoft Sandra, its a useful program anyway. You could try CPU-Z, its a small nifty utility, but I dont know what it will show, I'm not using my 5660 right now.
