Troubleshooting Steps Try these steps in order: Perform a Hard Reset Disconnect the AC adapter and remove the battery (if removable). Press and hold the power button for 30 seconds to drain residual power. Reconnect the battery and adapter, then try powering on. Check the Power Adapter Ensure the adapter light is on and stable.

The reset procedure actually is to disconnect the battery and the adapter. Then press and hold down the power button for 30 seconds. Then reconnect everything and try to reboot. Run a diagnostic procedure by tapping F12 immediately at boot. If it runs properly watch for any errors. That flashing amber light means a low battery charge. It is possible that the battery needs to be replaced or that the adapter is not charging the battery properly. If the adapter light stays on then a short is not likely. If possible try another Dell adapter. It is also possible that the DC jack is having problems and needs to be replaced. Least likely cause, the MB charging circuit is not working.

February 29, 2020Help my Dell laptop won't turn on I've done everything said from the internet
Dell laptops have issues with the power regulation chip. What you need to do is pull the back cover off and unplug both the main battery and the CMOS battery. You need to be very very careful removing the CMOS battery. Do not pull the battery out by the wires. I find it’s best to use a plastic pry tool of some form, whether it be a spudger, old credit card or some other thin semi-semi blunt plastic tool. If you rock the two sides back and forth then push out the connector down the center, it will come out. The CMOS battery looks like this: https://guide-images.cdn.ifixit.com/igi/rWTpWLLvSdZ36TQU.large Once you have both batteries unplugged, hold the power button for 60 seconds. Yes, really, 60 seconds. Plug both batteries back in and plug in the charger, then attempt to turn the laptop on. If all went well, the CPU fan should spin over a few times before the machine finally boots back up. Put the cover back on and you’re done. Source: I’ve been working in IT Support/Management with Dell as our main vendor for the last 12 years. More on reddit.com

That is really a mystery. If you are 100% sure VGA and HDMI cable to monitor are all working, then the only tests I think left to do is try this: remove both ram, does power button flash amber or pc beep then? install one ram back, try remove cmos battery for 30 min, drain system power by pressing power button and unplug power cord finally clear cmos settings by reset cmos jumper (#14 on board layout) on motherboard.

does power button flash? The computer POST (Power On Self Test) ensures that it meets the basic computer requirements and the hardware is working appropriately before the boot process begins. If the computer passes the POST, the computer continues to start in a normal mode. However, if the computer fails the POST, the computer emits a series of LED codes during the start-up. The system LED is integrated on the Power button. The following table shows different light patterns and what they indicate. Table 1. Diagnostics NUMBER OF LED FLASHES BEEP CODE PROBLEM DESCRIPTION 2 amber 2 No memory or RAM detected 4 amber 4 Memory or RAM failure 5 amber 5 CMOS battery failure 3 amber, 4 white 3,4 Recovery image invalid 3 amber, 3 white 3,3 Recovery image not found
