Re: Asus X302UA-FN188T (X302UA_UJ Rev 2.0) - doesn't boot
There's builtin RAM on board, I just tried external to see if it'll help.
Didn't check consumption on dc supply, connected it with the original adapter, I'll check it.
Powergood signals - don't have schemes :\...Leave a comment:

Asus X302UA-FN188T (X302UA_UJ Rev 2.0) - doesn't boot
Hello,
The laptop doesn't boot (black screen) after turning on. There were places with corrosion on the board, mainly on the EC, but not very serious.
Cleaned everything. After powering on the fan starts working and only the backlight of the LCD turns on (but very dim).
There is no signal from the HDMI connector either.
I tried to flash the BIOS but to no luck.

Why, how much should it be?
From the datasheet it should be Active HIGH...Leave a comment:

Re: Asus X509FJ-EJ115T (X409FB rev 2.0) - Doesn't work with battery
Ok, got it, so my only solution for now is to find a good battery.
Thanks guys, I'll update as soon as I'll find oneLeave a comment:

Re: Asus X509FJ-EJ115T (X409FB rev 2.0) - Doesn't work with battery
Don't have a good one, only if I'll buy. I'll try to find at the local labs, at least to check if that's the case.
I charged at the past some old Asus battaries, to check if they are dead or not if they were without a charge at all (some times there's a need to short #EN pin to GND). But it didn't help at this case....Leave a comment:

Tried today to charge the battery with a power supply, but no luck, it's completely empty and not charging at allLeave a comment:

Re: Asus X509FJ-EJ115T (X409FB rev 2.0) - Doesn't work with battery
My mistake, sorry
I copy pasted the measuremnets from the chip with an error - after pin 8 all the pins should have been shifted up.
Took new ones right now, very simmiliar to previous, here are the correct ones for the moment:
1 ACN 19.56
2 ACP 19.56
3 CMSRC 19.1
4 ACDRV 24.51
5 ACOK 6.046
6 ACDET 2.657
7 IADP 0
8 IDCHG 0
9 PMON 0
10 PROCHOT 0
11 SDA 3.27
12 SCL...Leave a comment:

At the moment it's stuck at low voltage, I'll seach what can cause this and update, thanks

Re: Asus X509FJ-EJ115T (X409FB rev 2.0) - Doesn't work with battery
Don't have a good one 🤷
But I'm thinking the problem is with the motherboard, because even without the battery it still shows the battery is 100% full....Leave a comment:

Asus X509FJ-EJ115T (X409FB rev 2.0) - Doesn't work with battery
Hi,
the laptop doesn't work with battery and doesn't recharge it, although it shows that it is 100% (even when it is disconnected).
Battery voltage measurement:
pin 1 and 2 (+) shows 0.85v
4th and 5th - jumps 3.23v-3.28v
6th - 2.91v
no 3rd pin, 7 and 8 are gnd
I looked for a #EN short for the battery on the board, but couldn't find it.
I also did a check with the BatteryMon program (photo attached).
Measured the voltage on the recharging chip (bq24780S):
1 ACN 19.56
2 ACP 19.56

Re: Asus X509FJ-EJ115T (X409FB rev 2.0) - Bad capacitor
Replaced with 10uF eventually, working good so far.

Re: Asus X509FJ-EJ115T (X409FB rev 2.0) - Bad capacitor
Yeah, it's (#16) going to to Gate pin of the MOSFET.
so, if I'm not mistaking it's C1 at hte datasheet, 10uF?Last edited by Dexomol; 09-09-2021, 04:18 PM.Leave a comment:

Re: Asus X509FJ-EJ115T (X409FB rev 2.0) - Bad capacitor
It's a smd capacitor. The voltage on him is 19V
In the new attached photo Iv'e allready removed it - the laptop works, but I want to put a new one....Last edited by Dexomol; 09-09-2021, 03:44 PM.Leave a comment:

Asus X509FJ-EJ115T (X409FB rev 2.0) - Bad capacitor
Hi,
Have an Asus X509FJ-EJ115T (X409FB rev 2.0),
the laptop weren't powering on, found a bad capacitor (short to ground) after a quick search.
I want to replace a new one but don't know it's rating (couldn't find any boardview / scheme).
Can some one help me find what capacitor to solder instead of the bad one? (picture attached)... -
