I have a dell g5 5587, i changed the fans and keyboard by myself (not the first time i dissemble it), the laptop is 6 years old, when i was changing things i kept the cmos battery connected and disconnected everything else, after finishing things when i was trying to boot up the laptop to check everything it didnt bootup at all, at first i thought it might be a power up button problem but after checks it seemed like its not, I removed cmos battery and plugged in the laptop with charger it immediately turned on (only keyboard and led) and then led flashed me 3 orange and 1 white lights, i reseated the cmos battery and tried again, same problem, sometimes with cmos battery hooked the laptop doesnt make anything other than flashing once i plug it in with one white light but then i wont be able to boot it at all and power button doesnt turn it on, I tried removing cmos and holding the power button for 30 seconds and plug it again but it didnt work, I encountered the same problem before but I solved it with the 30 seconds thing, is there any thing i can do and is it a big problem or a small one (im hoping i just need to replace cmos battery) could it be a power button failure too ?
