Re: Did I do anything wrong?
UPDATE:
Replaced ALL electrolytic caps on the power supply with Nichicon PS and PW caps; still has the random shutdown. Fires right up, boots all the way to Windows...and suddenly cuts off. Oddly enough, the WLAN module still keeps on blinking.
Odd, very odd.
Can someone give their insights?

Re: Did I do anything wrong?
I'm busy with other things right now, and short of money
The mainboard has two large radial KZG caps and some smaller Lelons (the small 5x8mm ones, I think). Once I have an ESR meter, I'll try to take a look on them....Leave a comment:

Re: Did I do anything wrong?
It goes into an unrecoverable 'standby' mode where the power button LED is still lit, but everything else is powered down. So it means the mainboard is still powered, but it has entered a powered-down state that it couldn't get out. Holding the power button long enough won't turn the unit off, I have to physically unplug it. I've seen it happen in the Dell monitor I recapped several months ago -- semi-bulged CapXon caps.
I've checked the HP motherboard and everything looks like fine (physically) for now, as I do not...Leave a comment:

EDIT: Got it to work...sort of. Let's see what'll happen in the next 24 hours.
EDIT: Worked, but still shuts off at random intervals. Hmmmm....Leave a comment:

Done that, including tinning the desoldering tip with 60/40 solder. It sort of worked, but not as fast as running my Hakko 936 at 405*C and a Soldapullt on the hole. Hmm, weird
The replacement caps are all Nichicon PW series as well as one PS cap (UPS1H470MED). I wonder if my selection of replacement caps has something to do with it....Leave a comment:

RoHS lead-free solder.
My Pace MBT-200 has had a hard time melting the through-hole joints. I've got it set in the max setting but it wouldn't budge. I've checked the board for any cracks, but I can't really see anything that would indicate otherwise.

Did I do anything wrong?
So I had this problematic HP Touchsmart 300 "all-in-one" computer sent to me. It would run for a few minutes, and then cut power off. Oddly enough, the LED on the power button would stay lit, but system goes on a complete dead stop. I checked the motherboard and everything (overheating and the like), and it looks fine. So that leaves the power supply...
Since this unit uses a propietary Delta DPS-200PP-171(a) power supply, it leaves my usable spare ATX power supplies out of the question for troubleshooting.
Previously, I successfully recapped a Dell E153FPc... -
Re: New Members - please post your introductions here
Hi all...
Came here because of a somewhat bodged recap of a HP DPS-200PB-171 power supply (5v does not show up).
Will post 'aboot' it later.
