Dell Inspiron 3147 won't wake from sleep mode
I bought a second hand Dell Inspiron 3147. It's running the A12 BIOS. I can't for the life of me get it to wake from sleep.
I tried researching this issue but nothing seems to work. I have a fresh Windows 10 Home install. I went to the Dell website and downloaded all the suggested drivers. I looked for power management settings under keyboard but it is missing on my machine. It's also missing in the mouse options. I ran the follow command in an elevated command prompt: powercfg -devicequery wake_from_any. Doesn't show the keyboard or mouse as being able to wake the machine. The touchscreen was listed but that doesn't work. The power button is listed but it doesn't wake the machine either. I set all of the HID devices to be able to wake the laptop, no go.
In power options, I tried setting the machine to shutdown once the lid is closed but it just goes black. I tried setting it to do nothing but my touchpad driver crashes after the screen turns back on. I have to reboot using the keyboard every time....
Also, suspend mode doesn't work in linux which leads me to believe it's an issue with the BIOS. Should I try reverting to another BIOS?
I should mention that I did have to take this computer apart to install a new DC jack. I had to remove the main board in order to get to the DC jack. Any chance a loose connection could cause this issue?
Thanks in advance for your suggestions.
