Acer :: 1810T: How Do I Disable Power Management On Bluetooth; Keep Bluetooth Fully Powered
Feb 8, 2010
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'm writing a C/C++ program to communicate between my HP 15-doo4au laptop and a DISTO D510 laser measuring device, which requires bluetooth 4 low energy (BLE).
Â
I can pair to the device in Windows 8.1, but bluetooth 4 doesn't seem available via C/C++.  If I call the Microsoft function BluetoothIsVersionAvailable(), it only succeeds for at most bluetooth 2.1.  Why?
Â
I suspect this is more a configuration/driver issue than a programming one.  Is there a better driver I need to install to bring this laptop's bluetooth spec up to full Bluetooth 4 support?

I just got the Aspire 1810t last night and upgraded my OS to windows 7 ultimate 64 bit.
I finally got all the right drivers on here and launch manager which fixed my Fn keys, however the Fn+F1 still doesn't work, that is what launches the power manager.
I'm only getting 5 hrs battery life without it, how to reinstall the epower manager and empowering technology software...

I have finally tested the Acer Empowering Technology software on my Acer D150.
Great news, the software works to enable/disable the Bluetooth module on the netbook without physically pressing the button. This is great for people like me that do not have the button on top to push the button inside. There are two software needed for people to get this running on the D150. First is the required “Acer Empowering Framework” software and the second is the “Acer ePower Management.” Once both software are installed on the system, the setting to enable/disable the Bluetooth module is in the ePower Management.
Power profiles within windows will probably be reset to default, so those would have to be readjusted if a user changed them. I am actually running Windows Vista on my Acer D150 with the Acer Empowering Technology software for Vista. I am not 100% sure if the software will also work on XP, but from the notebookreview forums, I believe it should work just as fine (but more options on other Empowering Technology software).
(in XP, the driver also works, but need XP edition, not vista editon).

I bought at DELL OUTLET a M6400 without the Bluetooth Module, I will buy it separate from DELL, do you know if the Bluetooth antenas will be Pre-Wired in the notebook ?,
actually I am buying the DELL 410 Bluetooth + UWB card, meaning I need the Pre-Wiring for Bluetooth and UWB ?

I noticed a few other threads around the internet about this issue, but couldnt find a definitive answer on how to get it fixed, so I thought I would try it here.
The problem is that when I go into standby and wake from it, my bluetooth icon disappears and bluetooth doesnt work.
I have a Dell Studio XPS 13 running Vista 64 with the Dell bluetooth 370 minicard. Ive tried using the generic windows bluetooth drivers as well as Dell's drivers.
Nothing appears in device manager as well. I have to manually go into bluetooth settings, disable the device, then re-enable it.

I was thinking of purchasing a Dell XPS 1530 for college. I have everything customized exactly the way I want it but I was wondering if the bluetooth option was absolutely necessary for college campuses? I really do not want bluetooth in my laptop if I do not have to get it as I hear bluetooth drains laptop battery power, but is it required by todays standards?

When I unplug my laptop from the AC adapter, Acer's ePower system automatically dims the LCD brightness to a setting that is 2 levels above the lowest (and 7 below the highest). However, when resuming the laptop from standby, I noticed that the setting is increased to 4 levels above the lowest (and 5 below the highest). I'm kind of a stickler for these sorts of things and would prefer for Windows not to change the LCD brightness if the ePower manager is supposed to be handling it. Is anyone else noticing this, and if so, have you corrected it somehow?
FYI, I should mention that I recently downloaded an updated version of Acer's ePower management system from Acer's support website - this updated version corrected an error that was occurring where my optical drive wouldn't "wake up" after ePower management shut it down, so I would prefer not to downgrade.
I'm frankly a little confused about where exactly all the Acer-specific power options are located. What is the difference between ePower and PowerSmart? Or are they the same thing? I could go on, but I think I've raised enough questions.

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.

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.

I just got a Acer One 751. It has an Atom Z520 1.33GHz CPU running at 1.24GHz.
When I'm running on battery it's not downclocking, it keeps running at 1.24Ghz. How can I downclock it?
My Samsung NC10 allows me to clock the 1.6Ghz Atom to 800MHz.

I have need to use Bluetooth stereo audio functionality (A2DP profile) almost exclusively when I use my laptop.
I had owned a M1330 with the Dell 355 Bluetooth Module for several years without issue. Last November, I decided to upgrade and purchased an M15x (laptop #1) with the Dell 370 Bluetooth module included,running Windows 7 x64 Ultimate. Not more than one day out of the box,the 370 module failed while watching a movie. It literally disappeared from device manager and no uninstalling/reinstallation of drivers alleviated the situation. The only way to get the radio to be recognized by the operating system was, and is, to shutdown,reboot into bios,disable the card in bios,reboot into windows,restart,boot into bios,enable the card and then reboot into Windows. The card would then work for awhile but eventually fail again. The module works for short periods of time but if put under an extended load,fails. That and other issues with the M15x caused me to return it.
Contacted Dell and returned the M15x and bought and built a Studio XPS 1645 (laptop #2) to replace it. Received the unit and literally within the 1st few hours,the 370 module failed exactly like the M15x.I thought o.k. a bad card and had tech support send out a new module for the XPS 1645. Received and installed it and the exact same problem happened. Failed when under an extended load. Again called tech support and was then dispatched an onsite tech to replace the entire motherboard and card. No resolution-card failed again. Spoke with a resolution specialist and returned it and again purchased a M15x (laptop #3-really liked the M15x over the XPS 1645)
Received the M15x-Bluetooth failure again. At this point, was considering dropping Dell altogether but thought I'd try the Studio 1558 (laptop #4) with the Bluetooth 365 module, in order to rule out the 370 card, first. Ordered and was delivered on the 5th of April, same exact issue-failure of card under a load. I am returning this defective Studio 1558 and again getting a M15x (laptop #5). I realize that the M15x Bluetooth card will fail again-in fact,am 100% sure it will fail,but have bought a Sony Bluetooth transmitter as a workaround.
What appears to be happening is that the card will shutdown when it gets warm.This is either a Broadcom manufacturing defect or a Dell engineering issue. I know now through personal experience that there is a serious issue with Dell Bluetooth cards.
If this was happening with only one laptop, I'd be ok with it but, this is occuring across multiple laptop platforms, with both Broadcom Bluetooth cards that Dell brands and sells.
This is either an oversight by engineering-maybe they didn't test the card under a heavy load, or Dell is knowingly selling defective equipment.

So my friend gave me his laptop to fix, and everything is perfect... except that the acer emanagement program doesnt have any power management options, like slowing down processor etc.
What can I do? Where could I find the proper Emanager?

Has anyone noticed that Optical Drive Power Management occassionally stop working, i.e., pressing the eject button on your laptop, Windows does not detect your optical drive? Does anyone know how to get Windows to detect the drive, short of restarting?
(my OS is Windows 7 Home Premium 64. I am using Optical Drive Power Management for Windows Vista Home Premium 64 - I just installed the program in compatibility mode. Before anyone suggests this is the cause of the problem, I was experiencing this same problem in Vista Home Premium 64 and was hopeful that Windows 7 would fix it...)

I have this acer with these two problems.
Firstly the power management button does not seem to work.
I have of course launch manager and power management programs installed.
When i press the button, it does light up green, but i have no indication on the screen like i have when i activate wlan or bluetooth.
When the drivers of the powersmart manager are uninstalled the button does not light up green when i press it, so it partially works.
Also, nothing changes in my power settings nor the screen brightens down, no sign that it works.
Actions i took so far:
I uninstalled and installed both programs, and i run them as admin.
I installed first the launch manager and then the power management.
Nothing changed.
I go to c: program files:acer:acer powersmart manager and try to open the right exe file which i think is ePowerMsg but then i get an error message saying that the element ePowerMsg stopped working.
The window is this:
Is this the right exe?
I tried with ac only, ac and battery, battery only, same results.

I have a Acer Aspire 5920G, it came without bluetooth, but with the button upon pressing it, a message comes up "No device"
I bought this from ebay:[url]
and fitted it today, the connector was available and space for the chip to sit and screw.
I started the laptop up, and the laptop did not come with any message about a new device.
I downloaded the driver from acers website this one:[url]
but when installing it it comes up with no bluetooth device detected.
I dont know what to do now.
Whilst fitting the bluetooth i managed to break the connector for my keyboard but ordered a new one which should come tomorrow or friday.

How I put the bluetooth back on my 5610? When I first got the laptop, bluetooth was enabled (I think) as there was a blue LED lit on the front of the machine by the sliding bluetooth control button. I have since had to reformat as I loaded some drivers for a Compro TV stick that was 'supposed' to be Vista compatible. Needless to say, it screwed everything up so I ended up just reformatting and reloading everything. I have been to the Acer FTP site as Acer themselves told me to do and clicked on the Vista link and downloaded the Bluetooth program and loaded it but nothing happens? No blue LED or nowt.

I have two questions my first one is my wireless internet, I have a switch that has a yellow light showing that it's connected wirelessly, before I formatted my computer I could move the switch and it would say wireless off or on. What do I need to download or do to fix this?
My second question is that I have bluetooth my bluetooth switch is beside my wireless, before it would glow blue, but now it does nothing and when I hit the switch bluetooth doesn't come on or off, and I installed the bluetooth driver for my laptop but it says bluetooth device not found when I hover over the icon in the right corner of my task bar.

Just wanted to share my upgrade experience with my Aspire 4736z. My model did not come with bluetooth installed from the factory and it only has 3 usb ports and I wanted to keep them as free as possible.
So I found a place that sells the bluetooth module and cable needed.
I installed the module and cable and everything works great. Installed the driver and now my bluetooth button works as it should.
Here is the link to the place where I bought the module from:
