5-5-5-3-2-1 beeps on my 17 R4 on start up. also 2-7 blink led indicator

Hi, laptop is 17 R4 I9-8950HK one it has hardly been used but recently it won't start.

LCD is just black without a backlight but tron lights are working This has been accompanied by five beeps which I believe is a cmos battery I've seen videos on YouTube of how to take the laptop apart which is going to take me ages if I ever do it at all.

Any help from Dell with this? The laptop does not have a warranty left on it.

Hi @simocmos thank you for sharing 17 R4 POST problems.

Dell beep code 5-5-5 = POST encountered Real Time Clock Power Failure, which mean that your notebook has CMOS BIOS battery problem. This is a wired battery assembly, Dell P/N 44YK6 or C8KT2.

Dell beep code 3-2-1 = POST encountered a memory problem. Reseating RAM cards is the usual fix. RAM cards are very reliable, clean with dry, lint free cloth to remove dust/debris and swap into different PCIe socket.

Dell Light code 2,7 = POST encountered Display failure. Reseating RAM cards might be the fix. Run the LCD Built-in Self-Test. Connect HDMI port to external monitor or TV, to check GPU is working.

I would replace the battery and then check the ram. It’s probably a display issue but maybe the fixes for the battery and ram might be the issue.
