Acer Aspire 5740G Owners Lounge

Hi Everyone,

I dont know if someone can help me out with a small problem I've been having with my 5740g.

I cant seem to change the brightness of my screen. The brightness keys do not work (ie Fn+Left/Right arrow) does not alter the brightness of the screen. When the mains power is switched off (ie laptop runs on batteries), the screen always stays on full brightness.

All other function keys (for example Fn+ Up/Down Arrow for volume control) work fine, I just cant adjust the brightness in any way.

Any help would be appreciated as it does tend to eat my battery life away.

Thanks,

Chada

 

Hmm I also have and interesting problem with my laptop screen. It may be the graphics card though, I'm not sure. When I play highly dynamic games, even old ones like NFS Underground 2, my screen flickers right in the middle. There is a line that crosses the whole screen horizontally and divides the picture in two. The lower end of the picture and the higher try to catch up with each other and they manage to do it. Do u know the nature of that problem? Any help would be gratly appreciated!

 

i tried flashing bios to ver 1.22 but it failed... this is the msg i got..

"driver(wdm)init fail!(0x130)"... whats wrong here..?

 

anyone knows how to fix "plugged in, not charging" issue? searched on google, saw many people having it on win 7. Anyone knows how to fix it permanently? (not the one with reattaching battery)

 

It's a common bug in Windows 7. Either restart your laptop or disable sleep under "close the lid" in power settings.

 

If this issue occurs when battery is between 95% to 100% charge level then its not a problem at all. Actually its being done to save the battery life. These very short charge cycles lessens the life of the batteries.

 

has anybody successfully dual-booted this with windows xp pro or vista32?

 

How i can use the P button as eco button ? and what is the third button after wlan and bluetooth button>? Are the volume keys iluminated?

 

yes..1st install xp to sepsrate partition then install win 7

 

You can't- P button works as a program-launching one only in this notebook. The third button from the left is meant to launch Acer Backup Manager. Volume buttons are not illuminated.

 

anyone pls..?

 

how did u install the catalyst xp drivers for the HD5650? i've tried using mobility modder but it doesn't detect the 5650

 

Anyone can shed a light why I keep on getting missing d3dx9 file errors when I have successfully installed a game plus the laptop already comes with DirectX11? And shouldn't it be backwards compatible?

 

Maybe you are missing some older directx files...some games install these files automatically. Yes this laptop comes with directx 11.
Download these files here and let us know if it fixes the error.
Download details: DirectX End-User Runtime

It just installs any files you don't have...

 

Awesome, thanks mate. Just installed and my games work fine now.

 

how did you installed xp without changing the ahci mode in bios


do you have the drivers for this laptop for ahci for xp harddisk , if yes then give me i will slipstream it .

 

Anyone know the part number for the keyboard? My brother-in-law's dog just damaged mine... but it's still usable and I don't feel like tearing it apart at the moment.
I've got the 5740G-6395
Thanks guys.

 

its been a while guys, miss me? i have a question, i am seeing some ppl saying pressing the bluetooth button enables it... With the 5740G-6769 ( i think thats the model) there is a driver that will make it work???

 

the 5740g-6979 does not have the bluetooth module installed (they sell it on ebay)...

 

no need for achi drivers if u 1st install xp..when u install win 7 next everything ll b fine...1st format the win 7 partition

 

umm xp installation won't recognise the harddrive unless it's set to IDE mode or you have slipstreamed AHCI drivers in the installation.. or you have a USB Floppy for F6 installation of AHCI drivers during setup

 

just for my curiosity... i haven't installed the alcor card reader drivers; there seems to be no need.
do they add something useful to basic support offered by W7 ?

 

I have no idea It's possible that they offer better performance or better compatibility with bigger capacity cards. I've seen cases (in Win Vista) where generic drivers couldn't handle cards above certain capacity while manufacturer's drivers could even though both should be able to handle it. This was hardware specific off course but as a rule of thumb I prefer manufacturer's drivers to generic ones- no one knows hardware better than its designers so they can make the most of it.

 

The Jack Information in realtek digital output properties shows that its an optical jack. Has anyone tried it yet?

 

well.. i think that, as far as it reads my SD cards, i'll go on with standard drivers

ps.
for my curiosity... have you managed to fix the issue with the P key light?
I didn't realize that the led survived the "reassignement" of the key.
it would be fancy to have it lit at will

 

That was not an issue- it was a feature
It's back to normal now but recreating it is near impossible- I have registry entries for moded Launch Manager meant for 5920G and actual files for a different Launch Manager.

 

i have the 5820TG.. it's optical digital out.. i have a 3.5mm toslink cable going into my logitech z680.. it decodes in 5.1

i'm fairly sure it would be the same for the 5740G

i had an MSI EX625 with a realtek HD 7.1 chipset too and it outputted via optical sp-dif

 

Thanks for replying.
Just one question. Does a red light emit from the jack when you enable the digital output through the realtek settings? Mine doesn't. May be it will lit after using the toslink cable.

 

hmm it doesn't seem to be emitting a red light.. i know it did on my EX625 though

 

@CVonV
It means emission of the red light is not a criteria for an optical spdif. Your 5820TG's 5.1 digital speaker configuration is working fine with the toslink cable (and that too without emitting red light). I hope it would also work in my 5740G.

 

yeah but all my previous experiences with optical spdif has emitted a red light.. like with dvd players, gaming consoles, set top boxes and what not.. oh well =\

no reason for it not to work on your 5740G.. what i like about the 5740G is that it has 2 output jacks.. my 5820TG only has one, a combined spdif/headphone jack

 

So does the 5740G- one headphone/spdif out jack.

 

yeah but it also has another output jack along with the combined jack

 

I don't think so- it's clearly marked.

 

oh the blue one is line in?

 

Hey guys,

I'm trying to get rid of DPC latency spikes on a friend's 5740G (he wants to use it for pro audio stuff which requires low latencies). Once every 20 seconds or so, he gets a spike of ~8000 microseconds length with WiFi on and ~2500 microseconds length with WiFi off.

Now, I've researched the issue a bit. Googling suggests other owners have spikes, too. But, so far, I couldn't find a solution.

Any thoughts?

 

Well usually it's networking related- Wi-fi, Bluetooth. LAN rarely causes that problem. I'd start with updating drivers one by one including all that may sound unrelated like card reader or sth.
There's some kind of app by Microsoft that allows you to pinpoint what causes it (which device) but I've long forgotten what was its name.

 

Thanks, downloads.

I'm still hoping, though, that someone knows what device/driver is responsible. I've already tried disabling some of the usual suspects--no success so far.

 

I've tested DPC latency and mine is really decent- up to 1000us one in while with Wi-Fi disabled (and up to 6300qs with Wi-Fi enabled and ON).
Few side notes- disabled means disabled in device manager- not switched off by Wi-Fi button. Secondly- all my drivers are up to date- including Realtek audio that has been released 3 days ago, touchpad, SATA, video, card reader and so on- you name it I got it.
Third thing- some of my devices are permanently disabled in device manager since I don't use them or don't want them to be enabled- this includes webcam, V90 modem and Ethernet card.

 

Emitting a red light (laser) does a criteria for an optical spdif. If not how it send signal to your speaker? On 5740G, it maybe get activated when you plug-in the appropriate device, e.g toslink cable. A lot of audio codec nowadays have jack detect override capability (meaning turned OFF or ON the input or output when it detect jack is plugged-in).

 

@downloads: thanks again, this is *really* good info. def haven't tried all of that (yet).

 

You are right. When I insert headphones the realtek automatically disables dolby settings in the properties. What I actually meant to say was that in usual cases the red light starts emitting when enabled through settings or everytime, no matter what you insert.
I tried inserting a hollow broken 3.5 mm lead but still didn't see the light (digital output was enabled). May be using a toslink cable and inserting its both ends (one in laptop and one in receiver) would enable it.
I wish it works because optical spdif is immune to EM interference.

 

it will work

 

Quick Question:
What is OpenCL, why GPU-Z shows that my Ati Card 5650 doesn't have it, is it essential and should i download it from somewhere?
Thanks.

 

open your ati catalyst control center and go to the info center ...there should be your openGL version

 

He meant OpenCL (Open Computing Language) not OpenGL.
In essence OpenCL competes with nVidia CUDA and MS DirectCompute (which works on HD5650)
OpenCL needs working software, not specific hardware- there is ATI Stream SDK that supports OpenCL on Mobility Radeon HD5xxx series.
That's all I know

 

Ah Ok...i thought he made a typo..

 

xp cd wont boot until i change the settings in bios ..

 

Damn.. CPU temperatures:
Core 0 : 90celsius
Core 2 : 92celsius

GPU temperature:
86celsius

Going to unistall this game "The Settlers 7". Too high temps .

 

Sound drivers i need to install from their homepage are "realtek HD"? This one: Realtek ?
