Hello and welcome to JustAnswer, I look forward to assisting you today. Feel free to disregard the Premium Service Offer. That is an automated popup initiated by the web site. Does your model have a removable battery?
Okay try this for me. Power it down then remove the battery and AC power supply. Press and hold the power button for about one minute then plug it back in and power it up.
Try powering it up with just the AC supply and no battery.
Have you made any changes in the BIOS or has there been any damage to it recently?
Well it is possible there is damage to the micro switch that puts the computer into sleep mode when the lid is closed. If that is the case, you may need to disassemble it to locate the switch to disable it.
Do you have the manual?
You may want to see if you can access the BIOS then reset it back to original settings to see if that wakes it. Give me a minute and I will send you a link for the manual.
Here is the LINK for your manual.
Even after you power it off you still see nothing on the display as it is booting up?
Humm! Well I hope this is just a switch problem and not a problem with the motherboard?
Just in case it is, don't forget to remove your hard drive if you decide to get rid of it.
What I would do is remove the drive then install it in a portable USB case that you can plug into any computer to retrieve your files.
That would be a good way to go then.
Well if you can't get the display up and no keyboard response there aren't many tricks left. You could try plugging in an external keyboard to see it that responds.
Usually that will initiate a reset. That is what has me concerned this might be a motherboard issue.
Possibly. It is worth a try!
Let me know how you come out with that.
Sounds good. That is most likely where the problem lies. Let me know if I can assist.
Glad to do it!
