Problem description
Repairing of a problem characterized by no power, drawing only 0.2A @ 15V from the charger and slowly drops. Without the battery plugged it, it draws ~0.275A @ 15V
Symptoms
- Not turning on
- Draws 200mA at 15V from charger and slowly drops, unplugging battery draws around 0.275A @ 15V
Solution
Likely dead CPU. Check if the infamous CPU cap near M92T36 is shorted. If it is, currently the only possible reason is a dead CPU. There might be corrosion or burn marks near MAX17050. There is another CPU cap near the SOT-323-6 IC close to MAX17050, if that is shorted as well then you can easily assume the motherboard is unrecoverable. Can be further confirmed by shorted capacitors around the MAX PMICs [source coming soon - ItalianRetroGuy]
