Re: Original XBOX Cap ripple current range
Thank you SO much for this information, its greatly appreciated and great knowledge to have. Think I'll just 2200's to keep it simple. Will use:
3 x 2200 on a 1.0 board in place of the 5 x 1.5's and
4 x 2200 on the other boards in place of the 3 x 3300s (if I run out of 3300s).
Thanks again!

Re: Original XBOX Cap ripple current range
Thanks, and just to be clear, did that yes answer apply to the fact those caps are ok AND both the follow on questions:
1) if I run out of caps at a certain capacitance can I sub a higher capacitance one if necessary (meaning can i put a couple of 2200's on in place of 1500s) without creating issues?
2) Could I, (again only if absolutely necessary such as I've run out of a certain capacitance) mix caps with different capacitance in the space near the CPU (as in 2 x 3300 and 1 x 2200 on a 1.6 board or 3 x 1500...Leave a comment:

Re: Original XBOX Cap ripple current range
Thanks for the guidance. I've looked and think I am going to go with the following, let me know if you see any issues with these:

Re: Original XBOX Cap ripple current range
I know Polymer is preferred, but I'm trying to build up my knowledge regardless so thats why I'm looking to see what is considered low / not to exceed ESR and the ripple current low/high mins I should be considering.
Thanks!Leave a comment:

Original XBOX Cap ripple current range
Hey all,
Looking to recap a six or so XBoxs comprised of every major mobo variant 1.0-1.1, 1.2-1.4, & 1.6 and am trying to decide on which Caps to get.
A) For the Caps located by the CPU, I know they should be low ESR/impedance, but what is considered low, anything less than 100?
B) Additionally, what minimum low frequency and high frequency ripple should I be looking for? I know higher is better but with so many cap choices and price points out there, I'm just trying to narrow down my search window.
C) I've read some stuff on the various threads... -
Basic electronic knowledge resources
Hey all,
I've got a few XBOX power problems but don't know much about anything concerning electronics troubleshooting outside of replacing caps. Instead of coming on here and wasting people's time being confused when they say check rectifier, transistor, resistor, etc or whatever it may be and then having to ask "what is that?", I wanted to learn and build up a knowledge base first so I'm not completely clueless and can apply the good advice people give without confusing the situation more by not knowing what i am doing.
Is there a good thread or source, either on this... -
Re: Toshiba P55W Battery peekaboo
Any guidance on the above? Wife has set a deadline by the weekend that she needs the computer to work on battery power and cheapest replacement battery I can find is $40 ... trying to avoid shelling out that kind of cash if it might be something on the mobo.Leave a comment:

Re: Toshiba P55W Battery peekaboo
What is the best way to do this without having to remove any from the circuit board? There's a lot of varying techniques I've seen, is there a video that describes how to do it best/most effective?
Thanks!Leave a comment:

Re: Toshiba P55W Battery peekaboo
BatteryMon and another battery analysis tool shows that the battery is still at ~75% of its design capacity and 100% charged, that is why I want to make sure its not something on the mobo before I shell out the money for a new battery....Leave a comment:

Re: Toshiba P55W Battery peekaboo
What voltage should normally be going to the battery (when charging it) and is it on a typical/standardized numbered pin 9 (e.g. the 1st, 4th, etc)? Does the lack of readings on a particular pin indicate it could be a ground pin?
Lastly, I imagine that the battery wouldn't discharge the 10.8v unless the laptop was drawing it...but in my checks with the multimeter I never got close to 10.8. If I removed the battery from the laptop, the connector for the battery was too small to fit the probe - haven't tried with a thin wire yet unless that...Leave a comment:

Re: Toshiba P55W Battery peekaboo
Thanks for the responses. I am back from vacation.
To answer questions thus far:
Pin 6 I wasn't able to get detect any DCV using the procedures and counting pin positions described in my original post
Attached is the BatteryMon. I can't get a reading on battery power as the laptop immediately shuts off as soon as the AC plug is pulled.
Thanks!...Leave a comment:

Toshiba P55W Battery peekaboo
Hello all,
Toshiba P55W-C5314 with a PA5208U-1BRS battery. Worked fine for months until a couple of weeks ago. Laptop will not turn on using battery power. However, powers on fine with AC power. Battery shows 100% charged via battery icon displayed in the bottom right corner and also by running BatteryReport so it seems to be recognized in some way - yet the battery charge status light on the case does not illuminate so maybe it doesn't?
I've tried the uninstall battery method and it didn't work. Neither did leaving it plugged in to trickle charge. I tested the power at... -

so if showing steady 5v at pin 1, is there anything else circuitboard based / other voltages it could be?Leave a comment:

5VDC showing at pin 1 on LVDS - with and without the ribbon cable attached to monitor and with the monitor attached to computer. Screen still full white. Power comes on and stay on.Leave a comment:

Re: Asus VW246H will not power on
Here are photos as best as I can get. I had to disassemble to get the photos.
To see the other sides of the boards I had to disconnect the pcb/panel ribbon from the screen. The pic with a red circle on identifying the PCB/screen ribbon where it is normally attached when fully assembled. The 4 inverter lights on the right side of the board are also normally plugged in but you can't see those on that view of the boards either. Hope this is close to what you wanted. oh, and don't worry, I have anti static measures and only placed on carpet...Leave a comment:

Re: Asus VW246H will not power on
Partial success! Thank you so much! I swapped a 47uF 100v into C606 and immediately had roughly 19VDC between JW20 and JW17. How did you figure out the startup Cap was C606 and had something to do with JW20/JW17? I completely hooked up the rest of the monitor and had power on the logic board and the standby board. However, the monitor would only come on with a complete white screen flash twice and then go back to standby. I took VDC readings on the logic board connector receptacle from the power board and to the monitor control panel from the logic...Leave a comment:

Re: Asus VW246H will not power on
Firstly, hope your dental surgery went splendidly, or as splendidly as something like that could go.
I plugged in the board to a GFCI without it connected to the logic board (logic board cable still attached to power board but its not to logic board - hope that doesn't matter).
Tested the VDC between the output terminals of the bridge rectifier and got 160VDC to verify my meter and power connection was working.
I tested the VDC between GND JW20 and Point A JW17 by putting one probe on each. I tried reversing the probes as...Leave a comment:
