Laptop sleep problem sleeps but doesn’t wake up
I have noticed that my 3 year old Dell laptop has a problem in power management. Either there is a problem in this laptop or this may ne common to all laptops in this series. So i am posting the issue to know more about it. Issue is this- once I put the laptop into sleep mode, I can see that laptop takes around 4-5 seconds and quickly goes to sleep. There is a LED for power which slowly glows and dims indicating laptop is sleeping. But while I try to wake up, by pressing power button, it doesn’t wake up at all! I have to press it long enough to put it in hard shutdown and only then carryon. Any solutions? Hints and help are appreciated.
