Hi,   I currently have a Dell Inspiron 13 Laptop 7348 with 8gb RAM running the latest Windows 10 build.  I have been on several builds of W10 over the lifetime of this issue.

 

Recently I upgraded my OCZ 240gb SSD to a Crucial MX200 500gb SSD,  I had originally replaced the original hard drive maybe a year ago without issues.

 

The laptop generally works fine and I usually keep it running, letting it shut off display and hard drive after being idle rather than sleep because of the issues I been having.

 

Sporadically, not all the time, after my pc is powered off either by shutdown or sleep (at first I thought it was just sleep), it won't power back on.   Its like when I press the power button nothing happens.   Even if I hold the power button nothing.   It does not matter if power adapter is connected or not.

 

The back lid has 10 screws, including one center screw.   For some reason, I suspect it might be physical and the center screw is maybe touching something or shorting something.   Usually the only way I can get it to start is to remove all 10 screws, remove the back lid, and remove and replace the battery.    

 

I am totally lost on how to resolve this.   I am thinking it doesnt really need the center screw but it would be strange if leaving that out would resolve the issue.

And it won't power up the normal way without the battery, with only the AC brick attached?  Have you already cleaned whatever contacts you can safely reach from AC brick to inside the battery compartment?  Reason for asking:  I temporarily had two used Dell laptops that did much the same thing; only for me, the contact cleaning made no difference - I hope it will a difference for your computer.

So the way the battery is held in place is 3 screws 1 okc which also goes through the center of the back panel. Trying to remove to do battery pull one got stripped. Wasted afew hours until finally gutsed up and drilled out the stripped screw. Sure enough after battery pull it booted fine. It makes no difference if the ac adapter is connected or whether battery is charged. Something to do with battery connection though..battery is just connected in one spot, right?

"1 okc which also goes through the center of the back panel."

--- What is okc?

 

If you suspect it has something to do with the battery, can you run the computer without the battery to test that idea?

Are you having any luck on getting your computer to power up?

I did .   After I do battery pull it usually starts up.    I had a tough time doing battery pull after posting this because one of the screws got stripped.  However, I am not sure if this is solved as I normally just configure my laptop to shut off disk and display rather than sleep.

Battery has been removed. Computer starts up. Power option is kept to shut off disk and display.

--- Need time to determine whether or not the “Can't power on” issue returns.

--- Please post back if the “Can't power on” issue does return

--- Did you leave the center screw in or leave it out? I don't see why it should matter, but if you suspect it might matter, leave it out for now.

--- That way if the issue returns you will know it doesn't matter

If the laptop only works without the battery and only being AC-powered, then Sleep is not a good idea!  Best to do a Shutdown or a Hibernate when you're done.  And, keep your OS partition and data partition backups current, you might need to restore the OS if a power-out or brown-out suddenly turns off the laptop during certain Windows operations.

So I noticed the center screw actually doubles as a battery screw.    After removing the stripped battery screw,  I put the screw directly in the one that doubles without going through the back lid.  I also have another screw in the battery.

 

The lid (rear panel) has 10 screws, which is a lot so I should be fine.

I just was looking at the service manual.   Removing/Replacing  the battery procedure has instruction that hard drive cable is suppose to be routed through guides on the battery. "Route the hard-drive cable through the routing guides on the battery"   Confused about that...

 

If you see the attached image, I did not route the hard drive cable through the battery guides.
