Good Day.
How about TOSHIBA SATELLITE A205-S5800
> I can use normaly use when battery operated. The moment I connect the the ac adaptor/charger the system hangs / freezes, no keyboard, pointer, hdd response, the thing I can only do is to long press the power button to shut the system off.
When the system is off and i connect the ac adaptor / charger, the battery charge normally, but when i tried to power it on it hangs @ POST, or sometimes doesnt boot @ POST.
> Tried also using it without the battery, result is still the same
I've tried disassembling unit to clean for dust @ air vents, CPU fan is working properly.
Conclusion: Motherboard problem @ power circuit part.
Tried asking @ PC Parts Shop for MoBo replacement and the price is Php14K.
>Tried also using other charger (same model, still same result)
OTHER UNIT PROBLEM (TOSHIBA SATELLITE MODEL)
>Operates normally and smoothly using battery power
>I can use the ac adaptor / charger but the system experiences lots of hang-ups. No keyboard, hdd, pointer response. Only long press power button will do.
>Battery charging state is good.
> Tried using without the battery, still same result.
CONCLUSION: Planning to open the ac adaptor / charger soon to check for capacitors. Will
diagnose the unit and the charger for high current.
> I've tested the ac adaptor/ charger voltage output, so far its good (19v dc)
Soon will try to test it with load (crossing fingers and hoping that its only capacitor problem on the ac adaptor / charger part)
With the two units, i've overhauled the motherboard (reseated cpu, cleaned air vents, using
compressed air to remove dust, crossed test the hdd with/from other unit (hdd is good),
crossed test the cpu with other unit (cpu is good), crossed test RAM modules with other unit
(RAM modules are good)
MoBo replacement is not practical. Price is too high.
Appreciate it if you can post some suggestions here.
Will post also results after diagnosis of the ac adapter / charger.
Thanks and GOOD DAY.
