Laptop wont turn on, please help!

[chris.s.butcher08]

Over the last couple of months, every now and then my laptop power light will come on and the HHD but the fans wont spin and the screen stays black and there's no sound.

The strange thing is that this doesn't happen all the time, sometimes it turns on as normal, however a couple of days ago I had the same problem and it still hasn't come on.

Things i've tried:
Cleaning and swapping RAM sockets.
Battery boot and test using AC.
CMOS battery boot.
Test for loose connections.
I run the laptop through an external monitor anyway, so thats tested.

Please help if you can, i've completely run out of ideas.

The pc is a custom clevo with 16gb Hyper x RAM and 960 Geforce.

Try the following and see if it will turn on...

1. Unplug your charger cord.
2. Remove the battery.
3. Press and hold the "Power" button for 30 seconds.
4. Now plug back in the power/charger cord.
5. Now put the battery back in.

If this doesn't help, then test the power cord to see if it is good. Either try your cord in another device, or try another devices cord in your laptop. You may also want to try charging it when the device is off, rather than on. If it works then, the cord is probably the issue.

Should that not be the problem, then check the battery to see if it needs replacing.

NOTE: While the battery may be complicated to get to, it should be replaceable. Unless it is under warranty, then you should contact the manufacturer.

Thanks for you response, however the issue isn't the battery, as I have said I have already tested this. Thank you though

Have you tested the charger to make sure it is putting out enough power? If it isn't then it won't be able to run. The same goes for the battery. If it isn't putting out the right amount. Also have you tested to see if the power is getting past the port where the charger plugs in.

Yeah I tested the battery and it's fine. It turned on properly not long after I originally posted but it's not working again now. The power light, fans and hdd are all on but nothing through the screen

Again, thanks for the help

If it is actually on, but the display isn't, try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

It's definitely not a graphics issue as the external monitor only works when the laptop screen does also. Also, the laptop and screen does turn on an function properly some times.

I see. Have you checked for loose connections? If not those, then I would start to wonder if the motherboard is having problems.

 

[c_butcher_08]

Yeah, I've taken it apart and had a look, but can't see any loose connections. I was thinking a motherboard issue aswell but sometimes the laptop turns on completely as normal and works fine until I turn it off next. So I don't see what the issue could be if it only happens sometimes.

 

[webworkings]

Still seems like something isn't connecting all the time. But at this point, since I can't actually see it, I can't say.

Okay, do you recommend I strip it down and reconnect everything?

 

[webworkings]

Couldn't hurt. You should also check the motherboard for anything that looks to be slightly singed or any loose connections there as well.

Okay, could new thermal paste work?

 

[webworkings]

If it was overheating I would say yes. However, while it can't hurt to apply new, I don't think it would cause your issue.
