Power Down / Take Out Battery To Let Motherboard Reload USB Drivers
May 10, 2011
so i am not intirerly sure this is the correct place to post it.Secondly, i think this is a problem that i have created myself and now i am unable to correct it.The jist of it is this. Whenever i try to active the webcam (Function + F10) a pop-up shows saying that hardware connected to a USB port is not recognized. This must be cause by the cam (which us buillt-in) is connected to the USB port on the motherboard.When i go to device manager, i can see that there is a unknown device connected, whenever the webcam is powered on.Btw it worked fine when i did the initial installation of the computer.What i have tried to do to resolve this is the following:
- Remove all drivers asociated with the webcam - reboot - reinstall from provided CD
- Power down, take out batteri (even for en entire night) to let the motherboard reload the USB drivers.
- Removed all the USB drivers and have tried reinstallling
I deleted som folders from my D: drive, (which is not the partition that has my windows directory installed) and there i might have deleted som crutial files for the webcam software to work.I have no idea on how to go on from here. This is a computer i have spend quite a long time getting up-2-date with all the programs i use for school and the exams are coming up. I would really like not having to do a clean install right now.
I have done a clean install of Windows 7 Homepremium and my battery life on my Vaio TX3 has gone from 6.5 Hours to only 3 hours. I cant find the power management drivers. Also I can no longer use the keyboard hot keys to adjust the screen brightness.
I have a toshiba satellite p300-160 and upon boot the bios password screen comes up and locks it out completley. I have search high and low on the net and so far had no luck.I have noted that removing the motherboard battery does not work on this model.I have tried to bridge the G1 connection to the ram earth for a minute but still get the password screen - The g1 connector is like a diamond shape with two points and I tried bridging both to the earth and each one seperate with no joy.Has anyone got any knowledge on this and how to remove/reset or backdoor it please?
I just completed a fresh install of Windows 7 on my Dell XPS 17. For some reason, when the computer is on battery power and is idle, the screen will flicker. Basically if I am on battery power, the moment I stop typing or using the mouse, the screen will flicker after about a second. Then as soon as I resume using the computer, it will flicker again. It will also flash at random other times... Only when on battery power (so far).As I mentioned, I just completed a fresh install of windows 7 after reformatting my drive because of virus issues. I did have some issues with getting drivers installed and still have have that are missing (see attached photo). I have not been able to get these drivers to install. One thought I had is that the screen issue may be a result of improperly installed graphics drivers? Just a thought. System Info:
When trying to install my Windows 7 Service Pack1 updates I keep getting this message "Your Computer is Running on Battery Power". I get the message even when the computer is plugged in. What could be causing this?
In XP, we had the option of executing a script when the computer switched from AC to battery power, and also when the battery reached a critical level. This was extremely useful because I had a special script run to send an email that the power had gone out and then hibernate the computer when it reached a critical level.
In the Windows 7 power options screens, I see no such options. Were they removed?
I have just been given a Fujitsu Lifebook S6540 running windows 7 and on the whole it is fine but it is eating the battery when switched off. Research on the internet has shown that the computer, although seeming to shut down may still be running in the background. I have therefore been into the registry and changed the powerdown after shutdown code to 1 rather than 0 which should ensure a complete shut down. I duly did this and let the computer charge up before shutting down and then left it for a day.It did not make a shred of difference and found half the battery had been use
My laptop wouldn't boot yesterday, the fan came on and the 'on' led came one, it beeped when I plugged in the charger but nothing on the screen and no post beeps etc. I let the battery drain fully, plugged it back in once it powered off and it booted fine. I shut it down last night and it did the same today on boot up, nothing. Again, discharging the battery fully brought it back.
My battery icon has disappeared from the bottom right hand side of my toolbar. I am using windows 7. I went into tray icons and the power notification is greyed out. How to get this icon back?
Anyways, in laptops (gaming or not), does setting the power plan to High Performance actually improve gaming (frame rates, speed and anything else) in battery mode? I'm using a laptop (not dedicated gaming, but suffices) and my games (the recent ones) slow down whenever I'm in battery mode. A couple of friends told me I should set it High Performance, which I doubted since they don't seem to be the type to change the power plan settings and more so with the advanced plan settings.
The system is built around an Intel Dual Core processor, Asus P5K motherboard running 4gb DDR 2 RAM and an ATI Radeon graphics card. I installed a new copy of Windows 7 Ultimate on a recently formatted hard drive and added and an extra PCI 4 port USB card. My issue is that all of the 6 motherboard USB ports are powered (I can charge my phone from each one) but do not recognise any device plugged into them. Have tried keyboard, mouse, usb drive, camera and so on. Windows doesn't blink when anything is plugged in. When I plug a device into one of the 4 ports on my PCI USB card it installs new device and is working perfectly with absolutely no issues. I have done the following:
- Removed power cable and small lithium MBoard battery overnight, - Flashed the bios several times upto and including the lastest version, - Checked that USB is enabled in all BIOS settings, - Downloaded and installed the latest Chipset drivers, - Checked that Device Manager correctly sees all the USB ports and drivers. Everything is displayed with no errors or flags. - Deleted and reinstalled all USB components. - Windows is fully updated including the language packs.
With my 4 port USB card working perfectly am I to assume I have a biffed motherboard? I just cant understand that as they have power and are recognised in Device manager. And were working perfectly with Windows XP Pro installed previously.
Over the last weekend I installed a new hard drive into my system, and on that drive installed Windows 7 Ultimate x64. Over the past week I have been tweaking my settings, resolving issues, and installing programs.So far everything is working fine, except for the fact that when I shut down, there is still some power being supplied to my motherboard (NumLock indicator does not turn off, and if I open the case the power LED on the motherboard is illuminated). This does not happen when I shut down from Windows XP (I have a dual-boot configuration; XP is on my smaller hard drive).
1. I have gone into my BIOS and disabled all the relevant power management settings (as far as what devices can wake the system, etc.).
2. I have gone through my Windows 7 power management settings and disabled/changed all settings that seemed relevant.
3. I have gone through my device manager and made sure that, for all devices that have a power management tab in their properties, the check box that says something like "Allow the computer to turn off this device when shutting down" (or something like that) is selected. Yes, even for the firewire port. There are some items for which the check box is greyed out and cannot be selected (such as the keyboard).
Here are the only things that I think may have an impact that I have NOT done:
1. Installed the chipset drivers for my motherboard in Windows 7. I have not done this because: a) other than powering down, everything else works fine; and b) I am not sure which driver package I should install (due to the mixed northbridge and southbridge chipsets on my motherboard).
I have an ASUS K50IE laptop that i had for 2 years now. been working fine until 2 days ago.this problem has been bugging me for the last 2 days. here's why.my laptop suddenly didn't detect my battery. thought it was because my battery was dead. I searched the net on things to do before "throwing in the towel" on my battery and today i came across a blog where the instruction was to uninstall the Microsoft ACPI compliant control method battery driver. I did just that and my battery suddenly worked! well sort of. now here's where it gets all weird.every time i open my laptop i do the following:1. plug in AC to laptop.. turn on laptop.3. unplug AC.3. laptop runs on battery.4. log on to windows.5. battery icon shows up as an empty charging icon then shows the "Battery is not detected" icon again.please take note that my laptop is still ON and WORKING. so this means (MAYBE?) that my battery is working.
When I activate the power management drivers,my laptop does not last 5 minutes, it goes into hibernation. But when drivers are disabled, I can run on battery for more than an hour. Where can I get drivers that work, because, as long as I run like this, i cant monitor battery energy level?
I have installed Windows 7, on my Vaio VGN-SZ660N and I`m having lots of difficulties with installing its new drivers.I can not install Windows Shared Library, So My Function keys do not work any more and more important I do not have my "Battery Care Function" any more which resulted in damage of my battery.where I can get "working drivers" for my Model? Because the ones on the Sony website do not seem to be working...
i have recently purchased an HP computer, that had Windows starter edition, i reformated the computer installed windows vista ultimate and then upgraded to windows 7, i have everythimg working fine, i managed to download most of drivers, my main concern is that card reader that i have in my computer doesnt show when i open my computer or computer,
