Hi
This laptop com to my shop i try to clean fan and add past for cpu but not help laptop working fine but trun off after 5 min
The problem is turn off after 5 min and fan high spanning but cpu and gpu temp its normal about 50 centigrade
I mixedup for this problem and do this :
Change io
Change rt8206b
Flash bios and ec
Change cpu pwm controller
Chang fan controller
Change cpu
I check this laptop with os and without Hard disk but same problem
Change with battery and without .. change charge ic


What the friend think about this?

Does it always take 5 minutes to turn off, or can it be quicker depending on how warm the board is? Is the fan always spinning at a high speed or does it gradually increase over time?

The fan in start system for some seconde slow and even some time stop and then take spanning high till trun off
And for turn off Approximately 5 minutes and sometimes a little earlier or later

Remove pq65 and check without it.
And also check 7p pu18.

Ok will do but can you explain about your idea please thanks

Try flashing the BIOS KBC using DOS, but don’t touch bios MAIN.

How can i do that ? I only know to flash by programmer device

This topic has a similar problem, but only with a 5741ZG laptop, so be careful.
