My brother has a Compaq 1525US laptop with a P4 2.4GHz, 512 DDR RAM, and 32 MB ATI Mobility Radeon 7500. When he plays BF1942 using battery power he has no problems at all, but when he has it pluged into an outlet the game randomly shuts down. He and I have played with the sound settings, which are known to fix alot of problems, but have had still no success. Any help with this annoying problem would be greatly appreciated.
I too am a Player on a portable, Dell I-8200. By default, when on battery power, the Power-Saver settings are on a "Lower Consumption" setting. This actually lessens the CPU clock-speed. It also lessens the Video processor power, at times not noticeably (graphically). Reducing power consuption also reduces the heat generated by these processors. By default, when on AC power, the Computer will switch to Maximum consumption and processing.... more heat..... lots more heat. Excessieve heat will cause a protective shut-down.
You will need to add additional cooling or reduce power while on AC.
That would be my first guess at your problem.
Uhhhhh.... don't have a second guess.
What you say is what I was thinking of as another possible reason behind the problem. Where do you go and what do you do to change the settings?
If you are running XP, look in the Control Panel for "Power Options".
Nvidia has a utility for balancing power usage on their cards called "POWERMISER".... cool. Perhaps ATI might have a similar utility??? I don't know. But, XP's Power Options will give you some tuning abilities.
Well I am his brother with the laptop, lol...
Unfortunately it does not appear that XP's power options provides possibly what I am looking for. The options it has available are things along the lines of "Turn off screen after X minutes of idle", "Turn off harddrive after X minutes of idle", etc. Nothing having to actually do with power being used.
I suppose the second post made is probably what is going on. When I unplug the AC adapter and let it run off batteries I can play the game perfectly fine up until the battery dies. When running on AC adapter, it just "randomly" "crashes" about 5 to 15 minutes into a game.
Looking for answers and help ASAP!
In "Power Options" near the top is a small click-open window labeled "Power Schemes". At the bottom of the list are two options.
Max Battery Minimal Power Management (my setting)
But I see your point. It's not enough to help your problem. Switching to "Max Battery" is probably ineffective when using AC power. Rats!
The alternative is additional cooling. But not knowing exactly what the problem is, that may be an expensieve venture. Here is a cooling unit that I'm looking at for $17 http://www.hardcorecooling.us/product.asp?0=305&1=306&3=362
It will cool my Laptop at work, but a pain to lug around. Plus, I'm concerned that it is USB powered, and will it put a strain on my Power Supply. And 25db noise? Not sure..... need more info.
My I-8200 gets hot..... real hot, while playing BF. It heats-up my wooden desk even though I elevate the back of it off the desk with Sticky-Note Tablets...... someday.... poof... Sticky-notes and all!
There are "tricks" that abound for Portables. For instance, on the Dell Forum I read, "Using the keyboard's aluminum backing-plate as a heat-sink is possible with a little bit of work". Hmmmmm..... something about smearing thermal compound under the keyboard and voiding the warrantee turned me off of that one. But you may want to look at some Compaq Forums and see what the population is conniving.
I had a portable blower I made (parts from Radio Shack) for my last Notebook. Blew it into the PCMCIA slots. Worked good till I left it behind in a motel one trip. Perhaps you should start there?
Well, whatever you do, I'd like to hear about it.
Thanks for the advice!
Was hoping you might know of a simple configuration or what not in Windows/BIOS that could change the power being used. I can say that you can visibly notice the power difference when on battery and AC just by seeing how bright it is on AC and then it goes a bit darker on battery, lol...
I don't really want to screw around or anything so I can play BF1942 on my laptop. I also have a desktop PC with Pentium 4 1.5ghz, 512mb RAM, etc... but with just 16mb of video (thus I have been using my laptop). Will probably just end up getting a 32mb or 64mb video card to put in so I can play it on my desktop. I just don't like the idea of spending $50+ (maybe less now? don't really keep track of video cards) just so I can play BF1942 (not a big gamer; only game I play often is Civilization III, lol).
Playing on my battery would not bother me so much, except that my battery only lasts about an hour when playing BF1942. In combination with the fact that the game does take a lot of power, processing, etc; my processor is a normal process, not a mobility one, and you can tell the difference in the power it uses.
There is a way to do it if your laptop supports it, underclock your CPU by lowering the FSB, this will slow your CPU down and it will produce less heat, hopefully this will reduce the amount of heat generated overall so that you can play extended time on the AC power.
:cya: :cya: :cya:
Thanks for the advice!
But I am pretty determined to just get the card for my desktop PC, which I happen to plan on getting later today or tomorrow.
Besides, I did not spend the money on my laptop as I did to have less than 2.4ghz at my disposal. But what should I expect when it comes to playing games, lol... They are not meant for games and I sure didn't buy it to play games on.
