My Latitude E7440 Laptop will not power on, the battery wont charge neither the light will appear for a second than turn off. The backlit keyboard will flash for a second before turning off the only thing that stays on is the power button which will flash for a few seconds.
I've tried clearing the static out and also tried turning it on without the battery in and both failed
If you can help please do and Thank you
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.
