Hallo All,
My son bought the Amilo D 7830 about 4 years ago.
Some months ago it stopped booting up. He eventually put it in the cupboard and got a notebook from work.
I have now got it and am trying to get it going again.
Symptoms.
Totally dead. Wont boot.
Battery seems dead. Mains charger working, tested with avo meter but notebook wont boot.
No power lights showing on notebook. New battery ordered.
On searching web I have read that this model has a Power Management Sytem Chip which is either faulty or can be reset. I am capable of dismantling the guts to reset whatever whereever this chip is.
Has anybody gots any answers, is it a metter of disconnecting the chip, shorting jumpers, holding a selection of keys when switching on.
Help, any thoughts would be appreciated.
Regards
Ralph

Several members report the exact same symptom: the Amilo D7830 is totally unresponsive (no power LEDs, no fan/HDD spin). ordered a replacement battery, and describe identical results, and troubleshooting so far has pointed at the laptop’s power and board subsystems (the display/adapter problem mentioned earlier may be a useful clue). The notes below give a short, ordered diagnostic workflow and practical board-level checks that address those hints without assuming a specific failed part.

  1. Verify the adapter absolutely first. Read the adapter’s rated output, then measure the DC jack with a multimeter while connected. A correct, steady voltage within ±5% of the rated value is required before any board work.
  2. Power‑drain / EC reset: remove the main battery and the coin (RTC) battery, disconnect AC, then hold the power button ~30 seconds to discharge caps. Reconnect AC only and look for any standby LED/fan activity.
  3. Minimal boot test: strip removable parts (HDD, optical, wireless, extra RAM) and try power with only one RAM stick installed. Also disconnect the display assembly — a short in the screen/inverter or cable can kill the whole board.
  4. Basic board checks (power off): test the DC input trace and the small SMD fuse near the jack for continuity; measure resistance from the input rail to ground (very low resistance indicates a short). If available, use a current‑limited bench supply set to the adapter voltage and a 1 A limit to observe current draw safely.

If those steps show a short or an open fuse, inspect visually for cracked solder, burnt SMDs, bulging capacitors, or damaged MOSFETs near the power path; these are common board-level failures. Reflowing joints, replacing the jack/fuse, or swapping obvious blown pass transistors often fixes a dead unit, but replacing controllers or multi-layer board repairs require specialist tools. Given the machine’s age, balance the cost of board repair versus sourcing a donor motherboard or replacement laptop. ESD precautions and basic electronics experience are essential; otherwise, arrange professional board-level repair.

I own the same laptop with the same problem.

Have you solved it?
Thank you.

(problem started with video adapter)

care to elaborate on what that means !

The power connector on the motherboard could be loose and need to be solderd. Can you get any power lights or battery charging lights if you wiggle the adaptor
