Asus R556L i5 / 820M Laptop - Matrix Blinks Under Specific Battery Conditions

Question

I have a rather specific problem.
The matrix in the laptop blinks, but only in specific conditions.
Namely:

1.Laptop Must work on battery power (there are no such symptoms on the charger)
2. The battery level must be less than 50% (when the battery is full or almost full symptoms do not occur)
3. The more loaded the laptop, the more often the screen blinks.

Talibanczyk · Answer

REV 2.0

From what I read on the net, replacing the battery does nothing

I met with the opinion that it is a tape - I do not believe it.

Replacement batteries are not available and hard to find anyway.

below are screenshots from batmoon both how it is connected and how it is disconnected.

ps this is not the fault of the graphics card because I turned it off in the device manager - first one and then the other and the effect is the same

RADU23 · Answer

One denies the other. If the tape was to blame, the same symptom would be on the charger (90%).

Talibanczyk · Answer

I am also of a similar opinion, although today I will be in the warehouse and check until the cost is low. about PLN 20

xoree · Answer

The question is because I haven't read it or there is no such information as the original charger or a replacement?

Talibanczyk · Answer

Both the org and the laboratory power supply - but what has to do with each other as here is about the operating conditions on the battery and not under the charger.

xoree · Answer

I had such a situation that a poor replacement power supply blew the gate in front of the charger inverter and that is how the matrix was blinking. The power supply itself was good.

And it was also Asus only X551 ...

lisek · Answer

You have the x555ld Rev: 2.0 disc kbc it8585e. charger bq735 You have MS and popapłam (e.g. p. 2), think and ... give the result

cezaro2 · Answer

Matrix replacement usually helps. Check if you set the brightness to 100% on battery power and the flashing will stop.

Talibanczyk · Answer

I understand up1589 for exchange

nuda · Answer

First, upgrade the bios, if that does not help, uninstall Asus power management software (if installed).
I had a similar symptom only the backlight went out completely, no matter whether on the charger or on the battery.
Here, damage to the tape or matrix would be ruled out if it works properly on the charger.
And enter the bios (f2 during startup) on the battery itself and on the charger, see if the image blinks if so you can exclude the problem of the software, but only after updating the bios to the latest version.

xoree · Answer

Did you take the measurements What tensions do you lack? Added after 1 [minutes]: Excuse me ? Added after 2 [minutes]: Reprogramming the BIOS with the latest batch is not a bad idea ...
