IT8586E in Lenovo L340-17IRH Gaming

[AGA058]

Hi Guys,

A few days ago my laptop powered off completely and switch on is not possible anymore. I unscrewed the back cover and measured some voltages according to a tutorial.

My 5V Always and 3.3V Always are good. 20V from power port are also available. What is not in a good shape is the 3.3V VLP. It is only 2.4 Volts and shortened to GND (checked with Multimeter).

So exact the same error like in this video: https://youtu.be/17HioZWT65c

And when connecting to power supply to the Mainboard, also the IT8586E will become hot. I can still touch it, but not for a long time because of the heat.

I expect that this chip is fried. Because I am very interested in this topic I want to buy a blank chip and flash it by myself.
Can anyone give me an advice on which programmer I should buy? Should the RT809F with PEB-1 extension do the job?

Thanks in advance.

Hey guys,

any suggestions for the flasher? It should not be that pricy because i will not plan to do such repairs on a regular basis.

Thank you in advance

Best regards,

If you're sure enough that ITE8586 is bad and dont plan to caary on with these type of repairs in future, then best bet is to buy a pre-programmed chip for your model.

However, RT809F with PEB1 will do the job. You can also look for verteyanov clones though SVOD is one of the best but perhaps unviable for one off repair.
