Acer :: Timeline 3810TZ Brightness Changes Automatically
Jun 24, 2009
I bought a 3810TZ with SU2700, but I have noticed that when on battery power and brightness set to low, the brightness of the screen would change automatically by itself according to the background. for example, the screen would darken if you have something dark open on the screen, and the screen would become brighter if you have a web page that's mainly white. Is this a feature in windows vista, or is the LCD screen defective?

I own an Acer Aspire Timeline 3810tz. My laptop did not come with an optical drive and now I'm wondering how I might go about downgrading it from Vista to Windows XP? I have already purchased a USB Cd-Rom drive and skimmed through some nLite articles, but I'm still getting the blue screen 0x0000007B error. I'm guessing it has to do something with the SATA/AHCI driver but I don't know what I'm doing wrong.
*During my XP install I changed the SATA Mode from AHCI to IDE
*I think I might be using the wrong driver, but I'm not entirely sure.

When I unplug (go to battery power), the green battery-light-led goes on and overrides the brightness-settings I do with Windows 7. This means whenever I plug-in or plug-out the brigthness gets reset to some value that Acer thinks is 'right' for me. I would like to decide myself what is right for me, but can't find out how.
What makes it worse is that at first it works like:
Unplugged: 30% brightness
Plugged-in: 40% brightness
Which is reasonable. However, after pluggin-in/out a few times, it goes all screwy. For example: unplugged becomes 50%, plugged-in becomes 10%, or some other seemingly random non-sense-making values. So, I would like to get rid of this.
Pressing the green led when it's on makes it go off and seems to give brightness-control back to windows-settings. However, as soon as pluggin-in and plugging-out again, the green led comes on again. Argh.
I read some other threads about similar issues, but people would always have Acer ePower Management or something installed. I do not. This happens on a fresh clean install of Windows 7. Bios is up-to-date. Happens in every power mode (saver/balanced/performance).................

i just installed Win 7 RC 64bit.
now, after every drivers/applications installed, i notice screen brightness goes up and down by itself, (it dims then goes back to bright).
This only happens when Power Saver button is pressed (lit green).
It did not do this with Win 7 32bit.
i assume, it is power saving feature interfering with win 7's power scheme.
Kinda cool.. but just wanted to know anyone else is having this *cool* trick..

I used the upgrade kit from Acer to do a clean install of Windows 7 to my Timeline 1410. Everything works great and I love this laptop... except that the brightness controls (Fn+Left/Right Arrow) do not work. It's locked at highest brightness.
I am at my wit's end trying to figure this out.
I have installed all the Win 7 drivers from Acer's site, particularly
- Newest bios
- Launch Manager
- Chipset drivers
- Intel graphics drivers
When I first boot it up, the brightness controls work fine during the BIOS steps. But once Windows takes over, the controls no longer function. In the Windows Mobility Center, there is no brightness control panel. [FWIW, my Dell, which does have functional brightness control, doesn't show one either.] All other Fn-combinations, like volume control, work fine.

Looking to pick up a laptop/netbook very soon and I am pretty much sold on going with the 3810TZ but now I am seeing a lot of talk about the 1410, which unless I am mistaken, is lighter than the 3810TZ, smaller, faster (not by much but has a 3500 cpu vs the 2700) and cheaper (450, vs best deal I can find on 3810 which is 550). Same features/memory/etc?
Any actual knowledge of when the 1410 will be released? I need it very soon (for a trip in a few weeks) and i cant tell from reading these forums if it will be out then or not until october.....

I recently got the Windows 7 upgrade kit from Acer in the mail. However, I have the timeline 3810tz (no dvd drive). How did Acer expect us to go about installing this? I know there is a way to put Win7 on a USB but it is tedious. I was wondering if there is any other way besides external dvd drive?
Also, how is the battery life lasting on Win 7? I've read it isn't as long compared to running under Vista. Currently I get anywhere from 6-8 hrs on a full charge.

One is marketed as business-grade, another is consumer-grade. Both look very similar and I am not sure if the materials used are any different. So tell me, as I am preparing to buy my next laptop.

I have an Acer Aspire 6935G with Windows Vista Home Premium
The problem is that bluetooth does not start automatically after a cold start or restart.
I have too push BT button every time to activate bluetooth on my computer.
According to Acer, I should be able to set BT by the the Empowering Technology software that BT should start automatically.
But there is no setting for this? How can we solve this?
Is there perhaps any other solution? Perhaps in Windows Vista or driver?

this thread is for all Acer Timeline owners who suffer from 100% CPU load, when only thing that helps is restart.
1. If you are a Timeline owner - having this problem or not, please do report here, what model you own and tell us how is this happening for you.
2. Please inform Acer about this, so they know and can offer a solution (especially if you're from United States as this will have greater impact rather than me telling this stuff to Slovak Acer service)
Alright, this is what I got so far about this thing:
-CPU will just go nuts at no specific time (idle, browsing, ...)
-Proccess explorer shows 'Hardware Interrupts' as source of 99.9% of CPU power
-unlogging won't help, only restart does
-updating BIOS doesn't help
-uninstalling acer epower managment doesn't help, even though it seems making these episodes less frequent somehow
Mine notebook is:
5810T with SU3500 and GMA 4500MHD.......................

I'm looking for a Timeline with:
Core 2 Duo Processor
the ATI Graphics Card (not integrated intel)
and a DVD Writer/Player
As to screen size I don't really care which it is, 13-14-15...I suppose I'd prefer 15, but any will do as long as the above specs are met.
I've read reviews that state the timeline series offers these specs but I can't find anywhere that sells a Timeline with them in it.

I actually have a Gateway EC1815U and heard it is identical to the acer 1810t.
In the Gateway bios (insyde) I see an option for a device on IDE1. IDE0 is used for the internal hard drive.
I am wondering if there is either
1- a way to expose the 2nd IDE externally to use like a eSATA device with it
or
2 - Be able to install a 2nd IDE device like a SSD to use that interface
I'm wondering out loud and checking here to see if anyone can offer some advice.

My 4810T has the fan always on (not too loud, but on nevertheless...). I can't tell if it's because of the CPU (intel SU9400) or the GPU (intel gma 4500mhd).
Is there any option where I can control this? I'm on Ubuntu and I'm using the "CPU frequency scaling monitor" applet to throttle the CPU, but even in it's lowest frequency, the fan never shuts down.

I had installed Windows 7 and it was working fine but it blue screened and now it won't start. Fine, I decided I'd just reinstall it but if I put my flash drive in it will just stick at the Acer Empowering People splash screen and won't move for a while and then just goes to a screen about something being not connected and then it'll boot to the normal start Windows Recovery (Which doesn't work) and start Windows normally. If you try to start it normally it'll either stay on the Windows animation starting or get to login and then i'll input my password but it goes to Blue Screen.
I formatted the flash drive using this guide [url]
I've tried having USB FDD and USB HDD as the first boot option and still nothing.

I was looking at the Acer Timeline 3810t and I am thinking about purchasing it because the battery life is great and so is the performance. Yet, the one thing I found that may hold me from purchasing is the stiff mousepad buttons brought up in many reviews. I was wondering if anyone who has this laptop has experience with the touchpad buttons. Are the really stiff that it would annoy someone who uses their laptop on the go without an external mouse?

I uninstalled all the extra software that this laptop came with. One problem i am having is every SECOND start up, the computers loads very slow. The next time i turn on the laptop it will load really fast and all the icons and stuff will pop up right away. Then the next time it will be slow again, windows load then only the wallpaper visible, the icons on desktop and the start bar is not there for about 2 mins.
I tried to restart and i noticed it is always on the second start up.
Also i tried to format my laptop with XP on a usb stick. When i get to the set up, it can not detected the harddrive but only the usb stick.

I'm looking at getting the Timeline 4810t with either the SU2700 or SU3500. Can anyone tell me any discernible differences I'll find between the two? Right now I'm looking at about an $80 difference between the two (also 1gb more ram with the SU3500).
Also, fyi this laptop will be for law school so it won't be very task intensive besides internet research, word processing, onenote etc.

I've previously had good experiences with HP until their past few models which have been a nightmare for a long, long list of reasons. But this post isn't about HP it's about Acer. This is my first Acer product and I've had a very positive response to the quality of their design but a very poor experience with the quality of manufacturing.
The unit I purchased is the Acer Aspire Timeline 4810T (1.4Ghz, 4gb, 14", 320GB WD) from Staples (US retailer) for the bargain price of 544.98 USD.
The most attractive aspects of the 4810T includes:
* The battery (wow!)
* The excellent, bright LED screen
* Fantastic keyboard (the fn key is to the right of ctrl, perfect!)
* Synaptics touchpad (the best)
* Super quiet fan even when playing games and doing heavy processing
* Decent speakers (dolby) with great sound through headphones
* USB ports on both sides
Some of the less attractive aspects include:
* Keyboard audio functions seem to rely upon software instead of hardware and can fail during heavy processing or if the OS hangs
* As a single piece of platic instead of separate buttons. The touchpad button only works on the edges with the center being "dead"
* No dock
* No expansion slot
* The speakers beep loudly when power is connected/disconnected if the speakers are on (annoying)
* The wireless light blinks during activity instead of just being on or off (annoying)
* The screen hugs the keyboard too closely creating key-shaped oil deposits on the screen (not uncommon but undesirable and a source for damage if something hard like a grain of sand is on the keyboard)

I have a 4810T (SU3500) and the wireless connection is giving me some issues. After a suspend or restart the wireless connection does not reconnect properly. Sometimes the icon says I'm connected but there is no data transfer. I have to disconnect/reconnect or turn off/turn on the wireless via the touch sensitive button. Once I do that the wireless connection is rock solid.
I'm using the newest Intel drivers and Bios version 1.23

how are folks preparing to upgrade their Acer Timeline to Windows 7? Are you assembling the drivers on Acer's website, or are you content to rely, at least initially, on Windows 7 drivers? For folks who will be upgrading to Windows 7 Home Premium 64-bit, what are you doing about the fact that there seem to be very few drivers and applications currently on Acer's support website?
I keep telling myself that Acer is going to release something, anything, in the next few days giving customers at least some guidance and help on how to get their Timelines fully compatible with Windows 7, but those are probably pipe dreams. So... as folks upgrade to Windows 7 over the coming weeks, it might be helpful to post experiences--good and, in particular, bad--for the benefit of the community.
