Does, operating system has any control over the power used on the laptop. I observed, that when i was using vista, the battery would last long. With XP , however is not supporting long.
Is the power of laptop, somehow related to OS?

First, I would check to see if your Battery is one that was RECALLED by following this link. Next, I recommend that you rule out the possibility that the Power Supply may be the issue/ Or the Battery may need to be replaced. Do the following:
1) Remove the Battery Pack and boot the system by using only the Power Supply. If your system runs normally without any issues, it is probably the battery that needs to be replaced.
Windows laptops include a few preset power plans for maximizing battery life, but you can also customize your operating system's power-management features (in Windows XP, under Power Options in the Control Panel; in Vista, under Mobile PC in the Control Panel). Setting aggressive targets for when the display turns off and when the machine goes into sleep or hibernate mode will help your battery last longer...
Hi there, remove the battery & run directly via power code. If nothing changed then, please restart your laptop when its booting press F8 key . You will find few option asking for selection. Select that by using up/down arrow key. Select " Last know good configuration" & press Enter. Next page asking for selecting operating system, for example: windows vista or Windows XP etc. Just select the operating system & press Enter again. ( Hope your laptop showing only one operating system ). Your laptop will start normally. After the if you seen the screen dark then press FN+Right arrow in key board(>). When you press FN + ( < ) or ( >) key that's time its working for brightness controlling for screen. Now if all well then fine other wise please let me know . Another suggestion is run your Acer driver DVD for installing Display drivers. When finish restart your laptop and watch whats going. If no success then format the Operating system & reinstall again.
Highly doubtful since both the Turbo C and Turbo C++ were created for DOS, Windows 3.0 and Windows 3.1. You might be able to use Vista's compatibility mode to run the program with disabled Vista features but I doubt it for a program that old. I think Vista's compatibility mode only goes down to Windows 98 SE.
-there is a possibility that the computer is searching for a bootable device; disable the drive A in the system setup -if you are using Windows Vista you may press F8 while the computer is starting up and select disable error messages on start-up.
My friend has one of these and I really Dont know why but VIsta is always the Operating system that causes this. Try this: at the log in screen press the F9 key see if it unlocks. unfortunately i doubt that that worked but hey it was a try Now try this: at the bottom of your laptop there should be a lever that releases the battery (remove the battery) leave it out and use your power cord only to boot the system. that usually works for me. Hope that fixes your problem. Thanks for posting on Fixya.com
try to run again the system restore cd, what OS you are using? is it old or new acer laptop? if you have new laptop with Vista OS it should be ok. if you have new laptop design for vista but rather installed XP maybe you will encounter difficulties loading drivers if you dont have xp driver cd (acer provided) if you have old laptop with XP OS it should be ok. if you have old laptop w/ lower memory and trying to install Vista it will not work or you will incounter difficulties
