RSMRST# Signal in CQ40 in Both AC and Battery Mode
RSMRST# Signal in CQ40 in Both AC and
Battery Mode
RSMRST#
At whatever point +3valwp and +5valwp
constantly control delivered reinforcement IC (TPS51125) yield or release
R_EC_RSMRST#( this is control extraordinary banner which is connect with ICH9
(Southbridge)D22 point) hail this banner is related with EC_RSMRST# through
R354 hindrance .So there is refinement between AC Mode and Battery Mode:
On off Operation in AC Mode
On off Operation in Battery Mode
On off Operation in AC Mode
In AC Mode connector is related and
system gain power from connector stick (VIN Signal) .When VIN is commitment
from DC jack it Power lm393 PU102 and it release ACIN from Pin no.7.

| The Technical Junction |
Exactly when ACIN hail input begin
from LM393 to EC stick no.127 EC cripple ACOFF stick no.27. This stick no.27
related with PU302 stick no.2 . pu302 is Schmitt-trigger inverter IC its Output
goes high when input is low. By this PQ308 entryway work and low the unfilled
commitment out of VL LDO Supply which is related with PQ305 and PQ306 passage
pins. Exactly when gateways of PQ305 and PQ306 have no power by this draw high
the ENTRIP1 and ENTRIP2. at whatever point ENTRIP1 and ENTRIP2 high Standby IC
(tps51125) start making +3valw and +5valw supplies.

In the wake of making reliably
supplies this IC release Power extraordinary banner it related with EC_RSMRST#
which make RSMRST# hail disable) for help Operation.

On off Operation in Battery Mode
In this Mode control for system is
Applied by Battery through discharging Mosfet PQ102 .When Power Button is
Pressed by customer it low (0v) on/offbtn on stick no.32 of EC. at whatever
point on/offbtn is crushed EC Triggered PWRBTN_OUT# from stick no.117.
 |
| The Technical Junction |
PWRBTN_OUT# go to ICH9 to infer
system to proceed with (release stop btn RSMRST#).ICH9 cripple the RSMRST#
(3.3v) banner and I/o release the EC_ON which control the entryway of PQ307
then its exhaust is short to ground. Exhaust of PQ307 is related with PQ305 and
PQ306 Gate pins.

| The Technical Junction |
Right when entryways of PQ305 and
PQ306 have no power by this draw high the ENTRIP1 and ENTRIP2. at whatever
point ENTRIP1 and ENTRIP2 high Standby IC (tps51125) start making +3valw and
+5valw supplies. In the wake of making reliably supplies this IC release Power
awesome banner it related with EC_RSMRST# which make RSMRST# hail disable(when
# signals has 3.3v it thinks about incapacitate) for help Operation
