Acer :: 1810t Abnormal Idle Power Consumption After X264 Video
Nov 19, 2009
Just got my new 1810t delivered today. Mine is the one with the SU4100.
Notice that at idle it goes to 5.5-6w. Great. After anything intensive I do it always drops down to that level. However, when i watch DXVA x264 accelerated video in MPC or WMP, i notice that after quitting my idle power consumption jumps an average of two watts. The only way to get back to normal idle power consumption is by putting the laptop into sleep mode, then waking it back up again.
Watching the same x264 video in VLC which does not support DXVA doesnt result in the increase in idle power consumption.
Watching DXVA accelerated youtube HD content with flash 10.1 doesnt increase power consumption either.
Running the latest (15.16.2.64.1986) video drivers, but the same problem was present on the stock drivers that came with the laptop. Version of those drivers was unknown. Wattage was measured using both batterymon, and batterybar.

Just did some tests on my new laptop:
(No, I don't write this software -- but some people are mighty interested in detailed power consumption statistics)
The BatteryBar Pro software has a Watt-Meter...
I decided to play with the power consumption of my new Timeline 1810T 11.6" laptop (Core2 Duo ULV 1.3 Ghz, 4GB RAM, 320GB HDD). These are really high performance laptops in a netbook-size form factor.

I recently bought a 5810 and Im having a far lower battery time then I expected. Even when running everything at maximum power saving in W7 I get no more then 3-3.5 hours or so. This is a huge bummer for me as it was the main reason I bought the laptop.

I am looking for a laptop with a matte display (at least 15.4'') and low power consumption, and so far I've selected these ones:
- Latitude E5500 (WXGA anti-glare)
- Latitude E6500 (Led backlit)
- Vostro 1720 (WXGA anti-glare)
(always with P8600)
I really like the Vostro 1720 features, but I am a bit worried about its power consumption (having a 17'' display, a NVIDIA video card, ...). There are very complete reviews for both Latitude models here:

The Studio XPS 13 should have a lower power consumption than the m4400 because of the small screen size(13"vs15"), lower power CPU(TDP of 25 vs 35), and a lower power graphics card (9200M vs 770M)...
Notebookcheck reports that the XPS 13 lasts 3hrs20min on idle, no wifi, and min brightness and 1hr10min under full load and max brightness...
In contrast they also report that the m440 will last 4hrs31min and 1hr35min respectively...

My Bluetooth keyboard goes to sleep after a period of idle and it takes 15 seconds for the Acer Aspire 1810T to wake up and notice the Bluetooth keypresses.
However, I found out my Bluetooth keyboard works reliably when I have a second Bluetooth device connected and active at the time (such as either a headset or bluetooth tethering to a cellphone as modem), the computer doesn't have a 15 second lag in noticing the Bluetooth keyboard again - the keyboard works almost right away even after being unused for sometime.
So that means the culprit is in the power management on the Acer Bluetooth module. Is there a way to force the Bluetooth module to never go to sleep? Any checkbox somewhere, a register setting? Even going as far to purchase a different Bluetooth driver? Or any other option? Sometimes the sleep is useful, but it definitely isn't useful with the Bluetooth keyboard. This problem does not happen if I use an external Bluetooth dongle.
(With BatteryBar Pro, I notice that power consumption falls suddenly whenever the Bluetooth module goes to sleep when the keyboard goes idle for more than 30 seconds, and at this point, it has difficulty 'waking up' when I start typing on the Bluetooth keyboard. But the problem also still happens when the laptop is plugged in!)

I have three drives: mSSD, HDD, HDD in ultrabay. I think this is taking its toll on my battery. My first HDD is often used since it has my "DownloadsFirefox & uTorrent" folders. However, my second HDD only has music. Is there a way to have it automatically power-off when I don't play music from that drive?

If I leave my M4400 idle with Windows (Vista Ultimate 32-bit) locked and the screensaver on for any length of time (e.g. 20 minutes), then the network card goes into power-saving mode even while on AC power, reducing the connection speed from 1Gbps to 100Mbps. I can see this because the colour of the LED on the port changes. The reduction in speed causes a brief disconnection from the network. When I unlock Windows, there is another brief disconnection as it reverts to 1Gbps, and this causes instant messaging applications to log out.
If I go to the Link Speed tab on the network card's properties in Device Manager and force it to 1Gbps instead of Auto Negotiation, it warns me that power-saving features will be disabled, but then I don't experience the problem and it never disconnects. "Reduce link speed during battery operation" is unticked, but this should not apply to AC power anyway. I've tried upgrading the driver to 9.50.14.2, A01 (released on 24/02/2009) but the problem still happens.
Does anyone else experience this?

Is it possible to have both ssd and hdd? Ok there is not enough room for both, but, beside that, could it be possible to use at the same time ssd and hdd?
Like ssd for os, and hdd for boot? Doesn't the mobo have 2 sata channel?
Btw could be a nice idea to use the pcie expansion slot where to put a 1.8 sized drive...

I recently bought a N-wireless gigabit router. It is DLink DIR-655. It is reporting the connect to my 1810T AGN wireless is using G. I'm wondering why if my computer supports N and the router supports N, why am I not getting N?
When I checked properties of my wireless card in my 1810T it tells me it is a Intel WiFi Link 5100 AGN. If I check the properties and it shows N is enabled. However, under Wireless Mode it is set to 802.11a/b/g. Also, while there are several options that include a, b, and g, there is no option for N.

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.

I've found out that the webcam is a Suyin, I installed drivers from acer website.. and the result is still terrible.
The webcam is so slow, like 1 fps. Even when not in videocall and using acer crystal eye webcam to set it, it's slow, pixelated and sloow.. I don't mind about the colour, yellowish but adjustable, but I do mind about the fps and quality.
I guess it's a driver matter, because the driver installed is the microsoft's standard one. But I couldn't manage to get better results, also some of the settings like auto and white balance or camera control are not selectable.

After a few days of happy 1810T ownership, the computer has begun to have a problem where the screen locks up tight. Nothing revives the computer except holding the power button down to force a powerdown. It reboots OK but shows the screen to optionally boot into Safe Mode.
The screen is a random color when this happens: sometimes green, blue or red. It is NOT the traditional "blue screen of death".
At first I thought it was due to some problems I was having with a conflict between The KM Player and Adobe Flash (as detailed here and here, for example). Luckily I had done Acronis 2010 images at each step of the way in the "new notebook" process:
- image made right out of the box by booting from Acronis disc first, before ever running Win7 on the computer (I call this the "Day 0 Image")
- image made after doing Windows Updates, Windows Security Essentials, installing apps (KM Player, IrfanView, FireFox, etc) and user data
Thinking the problem was due to the KM Player conflicts, I restored the computer back to when there was no KM Player, i.e. out-of-the-box Day 0 Image. This went fine and Acronis worked smoothly.
I did the Windows Updates but did not install any apps or user data... and the screen lockup still happens! Sometimes it happens soon after login, other times things run OK for a while first.
I am really concerned about this. If I can't rely on the computer to not lock up regularly, it is essentially useless to me. I am very surprised to see the problem even after an "out of the box" disk restore.
Any suggestions? Even if you don't have knowledge of how to deal with this problem specifically, do you know where else I can ask? What will Acer's take on this be? I am afraid they will just pass it off as "user error" and leave me stuck...
To Add:
1) I can't remember if this has happened only when on battery, or also when plugged in. I will check and see if it happens in both modes. If it only happens when on battery, at least that shows a path forward.
2) I have not tried to restore via the Acer eRecovery DVDs yet, though I don't know why this would be any better than the Acronis 2010 Day 0 image. I was in the process of burning the first Acer recovery DVD last night when... the screen locked up!
3) I have emailed Acer Support about the problem, though I suspect they won't trust Acronis 2010 and they'll tell me to restore via Acer eRecovery DVD...

I'm looking at picking up an AS1810T to replace my Samsung NC10 netbook and my HP DV8230US laptop.
I was looking at an MSI earlier due to its better warranty (3 years) and better price ($450 as opposed to $600)...but unfortunately, the lack of VT on the T6600 is a deal-breaker.
Does Acer have Virtualization enabled on the AS1810T? The SU7300 has it, but I want to make sure that there's nothing else that would prevent me from being able to use the laptop properly...as VMWare and XP Mode are requirements for what I'll be doing with it.

just got my son the 1810TZ and reinstalled with Win7 64Bit Ultimate.
I now cannot get the wifi to work no matter what. Thoughts? Is it an Atheros? I have installed the atheros package as well as all other drivers that say wifi with no luck...keep getting network cable unplugged and in system properties it identifies a network controller to which there are no drivers installed...
I thought Win 7 would pick up all poss hardware for the most part. I never had this prob on my 1810T-6188.

I have a utility reccommended here called BatteryBar. It has a category called Battery wear. What is battery wear? Is it as it sounds, a degradation of the maximum potential of a battery over time? Is there particular actions that cause an increase in battery wear?
I have a 1 week old Acer 1810T. Up until now the battery wear has been 0.0%. However, I let the battery run down to the point that the computer shutdown. I thought this was a good thing. I know in the old days batteries would develop a memory. They recommended a occasion full run down and charge. I think I read this is not true for the Lithium battery, however.
Well, after restarting my computer I see my battery wear is now at 1.4%. Is this because I let it run down? Also, if I want to my battery to last as long as it can, is it better to take it out when using it at home on AC power? That is about 90% of my usage.

I got my new 1810T and after opening it up, the first thing I noticed was that the touchpad buttons are not even.
By "even" I mean they're not level with each other. The left button sits a little higher on its right side and the right button sits lower on its left side.
Anyone else experience this? Is this something that has a simple fix like the double-sided tape for the mushy keyboard?
Also, I went into the device manager, opened up the monitor properties and when I choose "Hardware Ids" it shows this:
MONITORCMO1100

I've noticed our new 1810T's arrow and PageUp/PageDown keys often don't respond to presses, specifically when pressed higher on the key (along the upper border as someone says in one of the 1810T owner threads). This ends up happening quite a lot the way I situate my hands over the keyboard and the touchpad, and is a serious issue for me since I'm using these keys a lot in the development environment I use. As referenced above I've seen a few mentions of this issue on the forum, but no clear confirmation whether it is normal for the 1810T. Can anyone with a 1810T out there verify whether their unit exhibits this issue?

is it possible to overclock this version of 1810T?
I've read about a mode to apply, but it was for SU3500, I dunno if it's needed also for SU7300.
Second question, is: this Kingston Hyperix 2x4GB 800MHz memory at 4-4-4-12 timings compatible with this laptop?
