My laptop freezes when I connect the power cord, works well on battery

I want to check the motherbard in search for the faulty component,
where could I find pinouts and voltages to check for?

I don't know about acquiring a schematic for trouble shooting the MB,
but the first thing I would do is test the power adapter with a load
attached. I have repaired several that output the correct voltage but
failed to regulate when loaded down.
Also, some Toshiba Satellite computers were notorious for having power
connector problems. I trust this computer does NOT have such a problem?

no problems on the connector
tried different power supplies, even stabilized laboratory psu

Did you try cleaning the air ducts? When on batter the CPU 'may' be at a
reduced clock speed via Toshiba Power Management when on battery. When on
the PSU, the CPU will go to full speed and may just be over heating.

thank you, anyway please consider the laptop is completely teared a
part, non problems of air flow, and when connectinh power it locks

I'm sorry, I'm just forgetting pieces as I wrote this long story many
time in different newsgroups and forums, and still need to find a
solution.
Anyway I can still use the laptop on battery, or giving 12V with an
ATX PSU in place of the positive battery pole, leaving other battery
contacts in place.

Usually those things run off a 19 volt 95 watt PSU.

Have you looked at the MB power bus (+5v I would assume) for ripple
when you attach the external power supply?

this is what I am asking for, I tought I should measure it at the
socket pin holes, how can I idetify the +5V line on the motherboard?
And how would you measure (and fix the cause) a ripple on the bus? I
have a couple of scopes and multimeters for that, but how?

yes of course, but this motherboard does not like it any more, 12V
from the battery (or external, faking the battery connector) is still
ok instead

There's a second CPU (a little tiny one) that handles the power
sequencing. The 'BIOS pages' are only for the big CPU, it's that
little battery-monitor one that runs into some kind of trouble, and
it has that problem every time the external power is applied and
it tries to do the natural thing, run the computer from external
power and charge the battery. Somehow it senses overvoltage
or overcurrent and shuts down.
Look for small-value current sense resistors that are open, or
for semiconductor switches that are shorted (can't turn off).
There are often PMOS power switch transistors involved.
Also, look for fuses (they might not LOOK like fuses, though).
Battery charge current might be channeled through a switchmode
regulator, those have always had problems if a capacitor fails.

My guess is the hard drive is operating on +5v. You could measure it
there.

First determine if it has ripple. You can normally take a volt meter
set for AC and measure the ripple on a DC bus. Old VOM's used a cap to
isolate the AC from the DC component, but the new DVM's generally work
for this. If you did find ripple, look for a cap that is bad or
possibly a diode that is shorted. First determine if it exists.

Another agree, and they are very common.

Hello. I'm working on a Philips plasma TV 50PF7320 which refuse to
start up.
I've checked the powersupply output voltages and all low power
supplies operate, like 3,3V , 5V, 12V and so on. Also Va supply
(70VDC) operates ok.
But, the Vs and the other higher voltages for the Y and Z buffer
boards does not come up at all.
As soon as the powercord is connected to the TV, the powersupply goes
on for two seconds, and then shuts down in protect mode. I suspect
this is because Vs supply is missing and the undervoltage protection
kicks in.
I do have the service manual for the set. Unfortunately, in the manual
there's a Philips powersupply board, but in my set there's a Samsung
board called LJ44-00108C PS-504 PH rev0.7
So even though I have the Philips service manual I'm stuff at the
powersupply.
Any advice is warmly welcome!
Best regards
PAF

It may be, given your symptoms. But a DC continuity check isn't a good
indication of whether a cap is good or not.

Contact the manufacturer of the appliance that contains the motor. They
should know what size you'll need.
