Dell Inspiron 15-5567 not powering on.
I have an Inspiron 5567 that I saved from recycling so no history or background on it. When attempting to power on the fan spins full blast for 6 seconds and powers back off. No blinking codes just a solid white light that I assume is normal. Backlight on the display and keyboard do not light up. So far I have tried, unplugging the CMOS and regular battery while holding down the power button, reseating the RAM and trying a different slot, trying a different RAM stick, doing a bios recovery thing I found online (but it doesn’t POST so it can’t do that anyway) completely removed the logic board and inspecting for corrosion/obvious missing components, and bathing the board in 99% isopropyl alcohol while gently scrubbing with a toothbrush to no avail. I got it to power up maybe a minute aT the most and it passed the POST maybe a total of 5 times before doing the fan spin thing again. But it didn’t stay powered on and would freeze in the BIOS or while attempting to boot into a USB. Is there anything else I can do or is this thing dead?
Thank you
