Hi i am facing this problem that when i close the laptop lid for just 1 minute and after opening the lid the screen doesn't turn on (no matter how many times i hit the spacebar or any keyboard button or swipe the mouse) and the power lamp keeps blinking
The only option is to force shut down the laptop with power button
Any help ???
@ayush :-
A-ha. The old ACPI lid close issue. Well, AFAIK, it IS "fixable".....but not by me. Don't use laptops, me. Always been a desktop guy.
If I had a penny for every time this gets asked on here, I'd probably be quite rich by now.
It'll depend on the laptop model, the manufacturer, and how stuff has been implemented at the hardware level.......but several of the guys will be able to help you sort this one out. It's not hard, from what I understand; involves a bit of digging around in the file-system, and the creation of a small script.
We'll get ya sorted. Hang in there!

Two more things to try.
Press the left mouse button.
Tap the power switch.
Any settings in the computers bios setup, that controls what closing the lid does?
What opening the lid does?
I have attached my current bios setup, this laptop is a very old model from my grandpa's generation 
and uses PheonixBIOS 1.09
I disabled the LCD panel power saving but no help.
I clicked the left mouse button nothing happened, but when i clicked the power button the power lamp become steady but still the screen doesn't turn on, i waited for as long as 10 mins.
Opening the screen does nothing but shows me black screen no matter how long i wait and wonder when the screen will turn on
What is the exact make and model of the laptop?
What is Fossapup64 installed on?
Internal drive?
USB drive?
CD/DVD?
PC(lappy) specs:
RAM: 1gb
HDD: 120gb
Processor: Intel(R) Pentium(R) M processor 1.73GHz
Architecture: 32/64bit
Installation: Installed with Unetbootin
Installation type: Full, installed on HDD, windows and puppy are on different partitions /sda1(system reserved/windows files) /sda2(windows 7 ultimate sp1 64bit) /sda3(puppy linux) /sda4(linux swap)
It's a second-hand Wipro iValue WIVNB7B1600 laptop, probably the manufacturer discontinued making new laptops long ago and no official support is available currently for this trash, at least puppy linux gave some life to this old junk which would otherwise take 30 mins to load chrome on windows 7 ultimate sp1 
Now i can do all normal operations that a current generation laptop does, it saved my money 
A problem which has always raised it head for various combinations of hardware.
You will find a possible solution in this old thread.
You may try using cat /proc/acpi/wakeup to see if something happens to be disabled as a wakeup device. (In this case, everything)
To enable one of the devices, you write echo <device name> > /proc/acpi/wakeup If you use a USB, please do not enable XHC or EHC or USB.
Here's a thought. Use Fossapup64's Menu>Desktop>Screensaver Control. Don't close the lid.

Code: Select all

Device S-state Status Sysfs node
PCI0 S5 *disabled no-bus:pci0000:00
USB0 S3 *enabled pci:0000:00:03.0

USB2 S3 *enabled pci:0000:00:03.3
SLPB S4 *enabled platform:PNP0C0E:00
Here is the output of cat /proc/acpi/wakeup i did echo PCI0 > /proc/acpi/wakeup but no help only difference i observed is that the power lamp remains stable previously it used to blink and yeah i also pressed the power button once but still same
Have to know this.
Last time Windows 7 was shutdown.
Did you do a complete normal shutdown?
If no.
You always need to do that.
Windows is bad about not fully releasing control of the computer, if you do any other type shutdown.
If I am looking at the correct manual for your computer.
In the computers bios setup -> Boot section
There is option: RTC power on timer
Make sure this is disabled.
I haven't used windows since 1 month now bcz i am tired of the lags and freezes, i remember last time i shut it down perfectly sorry i forgot to mention that this problem occurs in my windows too but the screen used to turn on as i pressed the power button (unfortunately for puppy that doesn't work too) and it shows the lock screen but this is not how it should work right ? the screen should be turned on as soon as i open the lid and swipe the mouse or press any key
Do you have compton or picom or other compositor running? It might cause problems when waking from suspend. Or not.
My laptop wakes from suspend when the power button is pressed, or when the lid is opened or when any key is pressed.
If you run cat /proc/acpi/wakeup is something like PBTN enabled?
It probably should be enabled.
If you are using a laptop, is the backlight brightness set to 0 (zero) ?
you can set the brightness using brightness-set,
like this brightness-set 8
One thing i wanna make clear that i can wake up the pc simply by using the mouse or pressing any key when the lid is open and the screen turns off (for not using the laptop for long time) but when the lid is closed idk what happens to the screen that it never wakes up
Ah yes it's set to 0 what does it matter tho
If the brightness of the backlight of the laptop screen is set to 0
then the screen will be black.
If the problem is that the backlight is set to 0 after a suspend,
you can fix that easily. For example,
in /etc/acpi/actions/suspend.sh:
Code: Select all
echo -n mem > /sys/power/state
brightness-set 8
ps should tell you if picom or compton are running, like this:
Code: Select all
ps | grep -i picom
ps | grep -i compton
I have changed the brightness to 7 (max in my case) and then closed the lid waited for 1 minute and the problem is still there, also pressing the power button once didn't helped (in windows the screen wakes up immediately after pressing the power button, i wonder why tho ? normally it should wake up on opening the lid or moving the mouse) 
This is the output of ps
Code: Select all
root# ps | grep -i picom
12898 root 0:00 grep -i picom
root# ps | grep -i compton
12910 root 0:00 grep -i compton
This is the content of /sys/power/state
Code: Select all
root# cat /sys/power/state
freeze mem disk
The brightness-set command doesn't seems to be working is it just me or happening to all who are using fossapup64 ?
Also maybe this has nothing to do with this topic but previously when i clicked the lock icon on the top right corner it asks me to set some password for something, but now it doesn't ask anything no matter how many times i click on it. Actually i used to think that maybe that lock button is for setting up lockscreen like windows/ubuntu
The lock icon when pressed and has no password will prompt for one to set the password for the 'lock screen'. You can right click and click the option to clear it.
Closing the lid should execute /etc/acpi/actions/suspend.sh
On my laptop, the power light flashes on ... off when suspended.
I don't think the lid switch is broken.
Executing /etc/acpi/actions/suspend.sh in a terminal should do the same thing as closing the lid.
If the laptop's screen is black after it wakes (power light not flashing),
what does pressing ctrl+alt+backspace do?
If you see text on the screen, typing xwin then pressing the enter key should restart Xwindows.
Does brightness-set change the brightness of the laptop's screen?
(0 to 100 percent, for example, brightness-set 50 )
set-brightness command doesn't work no matter what value i set it to.
ctrl+alt+backspace does nothing
i can see no text on screen only black screen
power lamp doesn't blink
executing /etc/acpi/actions/suspend.sh does the same thing as closing the lid but there's no way to wake up the screen only option is to manually restart the laptop
note: just as i run that script it showed me "picom: no process running" something like that
You are assuming the lid switch is working 100% perfect.
Can you test using some other operating system?
I often have this problem with many Puppys on my older HP 6720s laptop. What normally works for me is to press the poweroff switch for a period (not too long otherwise the machine switches off) and then move the mouse. Some Puppy's do better than others but the mentioned method generally works for me.

Tried this no help 
I have the same problem when working with Windows on this laptop. Sometimes it works, sometimes it doesn't and then it's a freeze and you have to reboot. In my experience on my laptop it's about a 70% success rate.
