Keyboard doesnt start around 5-10 minutes after OS boot

[Paul Zodlav]

so someone i know had her laptop's some keys on keyboard not working so she uses external keyboard however even the external keyboard would only start after 5+ minutes
Laptop is i5 Hp dv3

things i tried
-Hp recovery factory restore
-i cant consider cold solder because the laptop is on heat/warm and when restarted the symptoms still exist
-keyboard on control panel
-used another external keyboard

i am thinking that this might be keyboard chip or hidden keyboard virus?

i was also told that the laptop is perfectly working before being put into cabinet for months and shipped

i just want to update since its been a week without reply

-im guessing that this might have been caused by moisture since the room is airconditioned (not sure)
-i dont know if virus resides on recovery partition but the owner(friend) told me it never had any anti virus since norton expiry which is free on hp laptops
-do i need to reheat the certain chip that causes the problem? please help!! thank you for reading sorry for bad english
-i also want to try installing fresh OS however i have to delete the original one
