compal IFl90 "unknown hardware"

Hello, i have ifl90 compal laptop.Windows XP pro SP2, intel core 2duo cpu t7500 @ 2.20ghz, nvidia 8600m gt video card, 160 hdd, BT, wifi, fingerprint scanner, and all other stuff
Everything works fine but the device manager shows me some kind of "unknown device" wich drivers i do not have. And I don't even know what is that? Here is all what I know in picture http://img525.imageshack.us/my.php?image=69226631yk7.jpg

Can anybody help me find out what is that? and where can i get drivers for it ?


another question is, is it possible to use IR receiver, someone in this forum said that IFL90 has build in IR near wifi switch(there is some kind of thing looking like irda) but i don't know any software to check it out. If it works , I will go buy remote for pc

thanks for any help

 

The IR could be for optional tv tuner for which, if you have one, there is a remote control. That's what I had on my ex-laptop(HEL80). But I could be wrong, hope that someone will correct me if I am.

Where did you get the drivers from? Do you have them on CD or did you DL them?

 

I have all drivers on CD. I was looking forward to download some, but in compal web site there was the same.

 

Have you installed smart battery?

 

yep thats probably the smart battery..

 

Smart Battery AFAIR wasn't in device manager. It's probably CIR.

 

it was on my system...

 

Smart Battery is installing an ACPI driver which will solve the unknown device.
If this isn't the solution then keep in mind this notebook uses the Realtek HD Audio, which you need to install trough a special patch this should be located in the Audio driver folder.

Good Luck

 

Smart battery installed, I will try my luck with Realtek HD Audio.


Anyway talking about smart battery i don't see difference in full charging and extended battery mode, processor speedstep isn't changing. But when i change my power management profile to minimal power through control panel processor frequence gets down to 800~ mhz. Should that normally be? I think smart battery should change speedstep too. (meybe I'm wrong...)

 

Smart Battery is only there to extend the lifetime for the battery
100, 75 and 50% are the options you can select, this will be something like selecting 50% the battery will be charged to 50% and then the charging process will be stopped, you can fully charge the battery then without selecting any settings just press the button on the left-side with the power connector pictured above it. then the SMart Battery tool will charge the battery to 100% one time only.

 

DO you know if you have the Turbo memoru module in the notebook, this can also be the unknown device, keep in mind Turbo memory support isn't there for XP.

 

I don't get the point of that... I always charge my battery to 100% even if there are 90% left....

How to find out about turbo memory? there are 2x 2gb ram installed in notebook, Bios shows 4 gb ram and windows shows 3 gb ram installed. I thought the video card take the rest of 1 gb ram. but video shows 512mb so where the hell is other 512mb ram?

Ram's are the same frequency and company....

 

32-bit OSs can only use 3GB of RAM.

 

hmm But if I change to windows XP Pro 64-bit version... I heard of incompactibility with some software and drivers... does all 32-bit soft perfectly works for 64 bit?

 

I'm running Vista x64 and don't have incompatibility problem but I don't know about XP... But there shouldn't be any drivers problem since everything is on the drivers CD.

 

thats the purpose of smart battery. doing that (charging from 80-90% to full) many times will help wear the battery out faster. smart battery "holds" the battery at a certain charge to prevent you from using one of its cycles.

most laptop batteries have say 500 lifetimes cycles they have for use..some more some less..

 

There aren't any official drivers for XP 64bit This OS is really a bad idea. If you want to use all 4GBs install Vista x64.

 

No I don't want to install Vista, couse it's an EATER of all pc resourses, so games like call of duty 4 will by laggy.

I tried to put /PAE , /3GB and /NOLOWMEM switch in boot.ini but that doesn't seem to work... nothing changed.


P.S just find out the unknown device :] that was infineon Trusted Platform Module

 

You couldn't be anymore wrong about Vista, most of us here are running it and can confirm that Vista isn't as resources hungry as you think and don't forget that you have a 2.2ghz dual core cpu 4gb of ram and a powerful gpu not the crappy gma950 equipped laptops that forged the bad reputation of Vista in the pre-SP1 era... COD4 runs fine(solid 30fps) at 1280x800 with a mix of medium and high settings (I have the same specs)... Hell there is a thread on the Windows part of the forum that tells you how to legally get an iso. Just get it install it (you don't need a key since you can use it unregistered for 30 days) and (re)make an opinion for yourself.

 

@Ayle: Could you point me to that thread about "iso". I can't find it.
Thanks

 

Just installed Vista ultimate 32bit. meybe Ayle is right about a bad reputation. Can't wait to test it out!

 

Is that allright if windows vista shows 4 gb ram, and performance tab under Task Manager shows 3069 MB physical memory installed?

...You should have installed the x64 version: the 32bit version can't see more than 3-3.5gb of ram....
