I have the same laptop. If the battery is removed and laptop is not used for two days the system comes up without the battery and works fine without any problem. But the moment I reintroduce the battery the laptop refused to come turn on . What could be the problem

hi sir! How many volts is the charger center pin?. Through the charging connector? i mean on the motherboard right next to the connector? i got 1.08v! it that right?። & my another qu/n, a standby(U900) IC have 3.3v but computer won't start & even have no charger light(Indicator). What could be the problem? Please answer me tell me the problem you suspect. i Thank you🙏
Quick question , when you powered the motherboard up by itself uf you had an external monitor connected to the VGA port would anything be displayed on the external monitor? Cheers..
This model use Display port and not VGA sometime DP port doesnot give out picture to external monitor until you have hard disk connected with Display driver installed,Thanks
@@northfixtz no worries mate.. i have this 9470m that i am trying every last effort before i purchase a new motherboard for US$100.oo...everything went to shit when i removed (and lost) the original HDD and unplugged the CMOS battery...i am going to pull the motherboard out and heat and look under the microscope...the fan sounds like it is spinning way too fast.. Thanks for your help.. You are a GURU.
