Re: Asus UX303UB charging problem green led blinking
For this application, the ACOK is pulled up by a resistor to REGN. So we know REGN is a good value of 6V.
This voltage value is used to boost the voltage on the ACDRV pin.
What is the voltage on the ACDRV pin?
After this check, remove all power. Then locate and remove the external resistor (~4k ohms) that will be in series with the ACDRV pin on the charger IC).
After this resistor is removed, what is the voltage of ACDRV pin? If all is ok, it should be ~25 volts = adapter input voltage + REGN voltage.
Confirm it.Comment

Re: Asus UX303UB charging problem green led blinking
With a 19v power adapter as the source, the voltage on pin #28 (VCC) is too low.
There should be a dual common cathode diode to feed power from the adapter or battery. Check the voltage on each pin of this dual diode. If still the voltage you posted, replace it.
Also with no power, check the resistance to ground of this VCC pin. Something is wrong here to drop almost 3 volts.Comment

Hi there,
I have this ASUS X453MA Laptop that's not turning on. When I plug in the charger, the green light just keeps on blinking and pressing the power button does nothing.
I have checked the charger and it is giving 19+ V
I have disconnected the battery and pressed power button for 30 seconds.
I tried another RAM stick.
Tried disconnecting the keyboard and touchpad.
Tried disconnecting the HDD and the wifi adapter.
The problem persists.
Hope you could help me out on this one. Thank you.12-14-2024, 06:40 AM -
I have the i9 version. I have tried disabling intel and Nvidia graphics in the device manager.
The laptop is just out of warranty.
The laptop continues to freeze randomly with the blinking amber charging light.
What could be possibly wrong with it?
I have also disable armoury crate in bios. -
Greetings
I got an Asus X453SA for repair
Symptom : no display, with charging indicator blinking, with or without battery. Power indicator is steady. When battery plugged in, the current consumption jumps, but the charging indicator is still blinking.
Here is the measured power sequence :
+3VA_EC +3.3V
EC_RST# +3.025V
+5VSUS_ON +3.307V
PWR_SW# +2.982V
3VSUS_ON +3.307V
SUS_PWRGD +3.386V
+1.05VSUS_PWRGD +1.061V
1.8VSUS_EN +1.873V
VSUS_PWRGD +3.383V
PM_PWRBTN# +1.830V

Hello,
I have an Asus X415EA board that is not charging the battery after some liquid damage. Everything else works, except charging the battery.
So far I measured all the pins on the bq24780s controller with the following result:
1. ACN = 0.0V
2. ACP = 19.02V
3. CMSRC = 18.5V
4. ACDRV = 23.9V
5. ACOK = 5.9V
6. ACDET = 2.57V
7. IADP = 0.17V
8. IDCHG = 0V
9. PMON = ?
10. PROCHOT = 5.05V
11. SDA = 3.3V
12. SCL = 3.3V
13. CMPIN = 0.47V
14. CMPOUT = 6.0V
15. BATPRES = 0.0V

Good Day.
I just replaced tcon on my sony kdl 65xg9505 and getting green amber leds blinking. all voltages are ok according to working sequence.
i downloaded firmware from sony and there is no .pkg fike.. after extracting it gives another file which contains multiple files like inf, payload.bin and 3, 4 other files. i just did that usb but did not worked. anyone knows anything how to do it..?
green amber blinking stops after while and then starts again. tv responds to remote control on off etc. before installing new tcon backlite was coming on without backlite...
