I recently had my toshiba satellite suddenly shut down, without a battery warning or anything.
It would not start up again, even after removing the battery, removing ram and hard disk and more.
When I plug in the power cord, it doesn't even show the charging light on the front.

Thanks

A focused, practical checklist to supplement points from , , and . These steps are ordered to isolate the power path (adapter → DC jack → input fuse → main power rails) safely and to preserve the drive and data before committing to a costly board repair.

Start with low‑risk checks that often reveal the cause: with battery removed and the machine unplugged, press and hold the power button for 30–60 seconds to discharge the embedded controller; reconnect AC (no battery) and observe any change. If a spare, compatible Toshiba adapter is available, try it (an adapter can measure correct voltage unloaded yet fail under load). Watch the adapter’s LED and gently wiggle the barrel at the DC jack while plugged in — intermittent LED or power flicker points to a bad jack or poor jack soldering.

If comfortable opening the chassis (battery removed, mains unplugged, basic ESD precautions), inspect the DC‑in area and battery connector for green/white corrosion, burn marks, or swollen capacitors. Corroded contacts can short power rails; light cleaning with 90%+ isopropyl and a soft brush can restore contacts but only after the battery is removed. Look for a small surface‑mount fuse (often marked F#) near the jack — continuity across that part is a quick, inexpensive test; an open fuse usually means the downstream board never gets voltage and is a common, repairable fault.

Preserve data before deeper work: if repair is delayed, remove the drive and attach it to another PC using a direct SATA connection or a SATA‑to‑USB adapter to copy files (be aware of BitLocker or other encryption). If the DC jack, fuse, or power MOSFET is faulty, a shop can often replace them for much less than a full motherboard swap; if no obvious power path fault is found, board‑level failure is likely and professional diagnosis is recommended.

there might be a problem with the power supply. please check with a customer service.

Always possible, but how was the battery charge? Mine just shut down, no lights or anything will display, but battery was fully charged and plugged in. I see some signs of possible battery corrosion or leak. Does the Toshiba power route through the battery (where a bad battery would terminate everything)? I know my old Acer could run without the battery in place.

Yeah I have seen this kind of thing before if no lights show up on the unit even when turned off but mains plugged in. To me that would indicate that the mainboard inside has gone and that wont be cheap to get fixed. So I suggest dig out the hard drive and put it in a external drive caddy then read the data that you need off of it from there.

Ps you can test the mains adapter with a multi meter but if the main unit is gone then that wont make much differnce.
