Aerogate Netbook H-S30 boot problem

[mikey5791]

Hi,

Have been using this low end netbook since
year 2012 without issue but suddenly it shuts
down after about 3 hours use. I reboot by press
on button, it starts but shut down again before
the bios screen appears. Not battery issue since
I plugged on the ac adapter.

So i thought it is a heat problem and open up
the casing. Cleaned the cpu fan using a brush
and i also reapply new thermal grease on the
heatsink. But it still shuts down after 3 second.

Appreciate for any help on how to resolve this
3 second shutdown. Thank you in advance.

Hi,

Today i try plug in ac adapter and do some voltage test.
On front of MB(motherboard), i put my black probe of
my Dmm(digital multimeter) on screw hole while red probe
on top right DC_JACK2 got reading of dc 21.3v. My ac adapter
output dc19v. Too bad i am unable to get any schematic on
this netbook.

Then i move my red probe to almost middle part of MB( near
chip U3) at FB2 and got reading of dc 3.7v. Next i probe at FB3
which also reads dc 3.7v.

Going further down on right hand side of yellow cmos
battery, i put red probe on +C180 and got reading of
dc 5.7v. Btw, i check dc on yellow cmos battery is dc 3.1v.

For info, i had attached front and back of MB. I did not
notice anything unusual on the back, so did not do
any test. Still will appreciate your kind help in resolving
no power. Thank you.

Hi ,

Finally got it, the culprit of auto shut off
after power on is the faulty wifi card.
Pulled it out of motherboard and netbook
start power up like normal now.

Case close.
