Re: Dell Vostro 15 3000 (i5-11th Gen) 3 Orange 5 White LED Code
Very annoying, spent so long working on it too. I guess its good for learning at least.

Re: Dell Vostro 15 3000 (i5-11th Gen) 3 Orange 5 White LED Code
I have tried removing/replacing/testing almost everything in RTC circuit with no luck, might just need to buy a new motherboard PCH likely dead.Leave a comment:

Re: Dell Vostro 15 3000 (i5-11th Gen) 3 Orange 5 White LED Code
+RTC_CELL_VBAT Res to GND is 0.750 Kilo ohm
LDO_3V3 (Think this is what you want me to check is) is 54 kilo ohm to GND

Dell Vostro 3500 (LA-K033P) RTC Draining/LED Code
I am making this thread as sort of a follow up thread to my previous one as issue on there was fixed. ([url]https://www.badcaps.net/forum/showthread.php?t=119200[/url])
When the charger is plugged into the laptop the white light comes on for about 5 seconds then fades out, then it starts blinking 3 orange 5 white (CMOS battery error LED code). This happens regardless of if there is a cmos battery in or not. I did change the cmos battery and it turned on for 1 boot and it said date and time not set (was still showing...Leave a comment:

Re: Dell Vostro 15 3000 (i5-11th Gen) 3 Orange 5 White LED Code
Nope same thing with or without cmos battery, only when it’s not draining it turns on… then it drains and won’t turn on next timeLeave a comment:

Re: Dell Vostro 15 3000 (i5-11th Gen) 3 Orange 5 White LED Code
Sorry for very late reply been busy, I have found the issue and replaced the 3V controller chip. It’s almost fixed i’d say, there was a cmos battery led code so I replaced it and got it to turn on once, it says date and time not set… i unplugged the power and tried again, no post just cmos led code. I have checked the voltage of the cmos battery before putting it in, it was 3.2V after the few minutes of it being in it was drained to 2.8V. Same thing happened with the old battery before but I just thought...Leave a comment:

Yeah motherboard is doing absolutely nothing now, all because a stick of ram?Leave a comment:

Re: Dell Vostro 15 3000 (i5-11th Gen) 3 Orange 5 White LED Code
Reflowed, 3VS and 5VS good, came up with no ram led, took out power cable, put in ram, put power cable back in, now no lights and no voltage on any coil. Took out charger and ram, put charger back in, no lights and no voltage on any coils, flashed back to original bios, still nothing. 19V comes in, I have kind of probed around and 19V goes to PQG4 mosfet but nothing comes out, not sure if this is the issue though.Leave a comment:

Re: Dell Vostro 15 3000 (i5-11th Gen) 3 Orange 5 White LED Code
Well, I checked it and I pushed hard on it while powering the board and got no RAM error, so will reflow it later. AwkwardLeave a comment:

It looks fine, I could probably go over it again later.Leave a comment:

Re: Dell Vostro 15 3000 (i5-11th Gen) 3 Orange 5 White LED Code
Sorry, I had flashed the bios back to the original to see if it was some how a bios issue, and then 5VS went to 5V and 3VS dropped to 0.04V. Then the 3 amber and 5 white LED started flashing again. Later I will reflash to a different bios and clean ME but I need to wait for my flux to arrive later in the day.
I have tried reading the resistance to ground again on 5VS and 3VS rails.
Im getting around 1.2 mega ohms on 5VS however it keeps climbing, I have no clue why this happens. Tried...Leave a comment:

There is no shorts to ground on the board, Unless there is 2 rails shorted to each other idkLeave a comment:

I put it back into case and plugged everything back in and it went to 2.2V againLeave a comment:

Re: Dell Vostro 15 3000 (i5-11th Gen) 3 Orange 5 White LED Code
Im not too sure why but I got home and tried another charger and now 5VS reaches 4.7ish volts, I dont know if its because of the different charger or if by some chance I read wrong multiple times im not sure. Anyways Im trying to measure resistance and it first reads 20 mega ohms then it keeps going down so not too sureLeave a comment:

Re: Dell Vostro 15 3000 (i5-11th Gen) 3 Orange 5 White LED Code
Update: I changed UZ2 chip again, now 5V and 3V go in correctly. 3.3V comes out on 3VS but only around 2.2V comes out on 5VS. After it goes to 2.2V the power light goes out and then it comes on a few seconds later and it loops. RAM, CPU and GPU heat up as normalLeave a comment:
