Hi! An urgent help is needed for Toshiba A205-S5825 regular shut down issue.
Platform : ISKAA LA-3481P Rev : 2A
Steps already taken :
1-cleaned fan system (was a little dusty but not clogged), removed dried paste and applied new one to CPU and GPU.
2-Tried naked mobo with a working ram, CPU, KB and Lcd display, enter bios screen, lap always shut down after about 1'50s.
3- Scanned mobo with an infra-red thermometer, Max temperature registred 42° at SB, so no heat issue.
4- Checked Thermal Sensor ADM1032ARM :
VDD : 3Vs
D+ 2.38V
D- 0v
EC_SMB_CK2 and _DA2 : 5.6V each
pin 4 "Therm#" and 6 "Alert#" not connected.
Please note that CPU of A205-S5825 series doesn't use big "Nec-Tokin cap" but 330uf small caps.
Also Tried with Mobo +ram +fan but without CPU it also shut down at about same time.
Has any one dealt with the same issue, or any clue as where to dig further
Thank you
