Why is my laptop not powered on?

Hi @izainfarooq

Try a full power refresh in case it is a corrupted BIOS and check if that resolves the problem.

Here’s the procedure:

a). Disconnect the charger from the laptop if connected.

b). Remove the main battery from the laptop.

c). Disconnect the RTC (Real Time Clock) coin cell battery from the motherboard.

Here’s the service manual for the laptop. Click on the coin cell battery link in the Contents section to go to the section in the manual that shows how to remove it.

When the RTC battery is removed measure its voltage. If it is <2.6V DC replace it. Search online for Dell D430 RTC cmos battery to find suppliers that suit you best.

d.) Press and hold the laptop's Power On button for a full 30 seconds and then release it.

e). Reconnect the RTC battery (or its replacement).

f). Re-assemble the laptop and reinsert the main battery, connect the charger and try to turn on the laptop.

If it starts OK there may be a message about the date and time being incorrect. This is normal as the BIOS has been completely reset back to its default settings. Once the date and time have been adjusted the message won’t appear the next time that the laptop is started.

If you had previously changed any user defined settings in BIOS to suit whatever specific hardware configuration that you had for the laptop, then these will have to be set again.
