Re: Dell n5010 can be converted from graphic version to non graphic
working like a charm, first try.
only extra parts needed are 4 resistor networks, xtal stuff and inductor. rest is on the board (exchange)
Intel mobo btw.
thanks!

Re: Toshiba L670 power problem
yeah -- DCIN is 0v as it's only charger. And PQ11 is off.
I get 16V on PQ11 without battery -- and it drops down to 10V with battery.
What I'm concerned of - is the B+
check image for more.
is there a short in volt rails ?...Leave a comment:

Re: Toshiba L670 power problem
looks to me that charger circuit is working fine. low voltage might been due to shitty battery.
Will check EC when I get back home.
and whats up with B+ ? on scope it looks like normal DC voltage, but has a bump down every second or so. and when Button is pressed it drops dramatically ?Leave a comment:

Re: Toshiba L670 power problem
AC only:
19=15.7V
20=15.5V
22=1.5V
(rest is mV or 0)
AC + BATT
1=5.11V
2=5V
3=2.89V
5=5V
6=5V
8=2.3V
10=0.5V
11=0.6V
15=5.1V
16=4.7V
17=4.7V
18=3.5V
19=11.3V
20=11.3V
21=3.5V
22=3.5V
24=11.3V
=====================
BATT pin -- 3.5V
as per schem -- PQ17 -- AO4466. board has AO9636
but has 11.4V as on charger circuit....Leave a comment:

Toshiba L670 power problem
Hello folks!
So - I have this Toshiba L670 with a power problem. Laptop came in with corrupt BIOS, reflashed BIOS, laptop booted fine, and eventually it came in for repair again.
Symptoms - AC only - Adapter light ON, when trying to power up - Power led blinks, and it resets to beginning.
With battery and AC - sometimes it powers up, eventually shuts down due to battery being empty (Bat led blinks, and beeps. !! charger still connected!!)
Scope measurements -- everything is fine til VIN is converted to B+ (schematic page 36 (S:36)
VIN is nice... -
