Dell Latitude E7270 12.5 inch laptop

Power Button light on, laptop not turning on

The laptop was left untouched on a table no one uses for about 2 weeks (so no environmental issues, and it's used lightly with a vinyl cut machine program). I went to turn it on, and the power button did not blink/turn on. I plugged the laptop into the charger, and the power button lit up immediately. However, the laptop does nothing else. There is no sound of it turning on, no blinking lights, no screen light whatsoever. Just the power button light steady on.

I've removed the back cover, removed the battery, held the power button in for 30+ seconds, reinstalled battery & back cover, no change. As soon as the power adapter is plugged in, the power button light immediately turns on and nothing additional happens.

Any ideas?

Hi Amanda, thank you so much for taking the time to answer despite this being an older post! I'm glad you got your laptop back to working. Unfortunately I didn't know how to open mine and do the same, so I took it to a technician and he told me he had to change a circuit or something on the motherboard, because it wouldn't provide power to it. It's fixed now. Hopefully he didn't rip me off and he indeed fixed something in there.

Hi,

Sometimes the power refresh that you performed is not enough. You need to disconnect the RTC coin cell battery from the motherboard as well.

  • Disconnect the charger if connected.
  • Disconnect the main battery.
  • Disconnect the RTC coin cell battery - here's the owner manual go to p.15 to view the procedure. If you have a DMM (digital multimeter), check the voltage of the RTC battery when it is out. If it is <2.5V DC replace it. Search online for E7270 RTC battery to get suppliers
  • Press and hold the Power button for 30 seconds.
  • Reconnect the RTC battery, reconnect the main battery, reassemble the laptop, reconnect the charger and check if it turns on
