Hi,

My Sony Vaio is dead, it doesn´t start anymore.
I surfed on internet last night and today in the morning it doesn´t start up. Nothing on screen, no led, no sound, no..nothing. I tried everything, plugged with battery, unplugged with battery, plugged without battery, removed and reinserted the ram etc.

Any idea?

thanks, daniel

Short summary and where to focus next: already tried the obvious (battery swaps and reseating RAM) and gave the correct first-line idea of a power/reset attempt. When there are truly no LEDs, no fan, and no drive activity at all, the fault is most often in the power delivery path (the AC adapter, the DC jack/connector, or a power/fuse/regulator on the mainboard) rather than RAM or the display. (vaiosupport.zendesk.com)

Practical next checks that add value beyond a reset: verify the AC adapter is actually delivering its rated voltage (label on the brick) with a multimeter or by swapping in a known-good, compatible VAIO adapter; look and feel along the cable and plug for damage; and inspect the laptop around the DC jack for looseness, burn marks or smell. If the adapter measures correctly but the laptop is inert, the DC jack or the board input circuitry is a likely culprit. These are standard troubleshooting steps and commonly solve “no‑power” symptoms. (vaiosupport.zendesk.com)

What to expect if you open the case: on many older Vaio models the failure is a cracked/broken DC jack solder joint, a blown board fuse (polyfuse) or a failed regulator/MOSFET near the input. Replacing a DC jack or a small fuse is inexpensive; diagnosing board power rails requires a meter and the service manual. If you are not comfortable with board‑level work, a repair shop can quickly confirm whether the jack/fuse is replaceable or the motherboard must be swapped. (vdoc.pub)

If data matters: remove the hard drive and read it in a USB enclosure or another PC to recover files before committing to repairs or replacement. If the unit shows burning, swelling, or you’re unsure, stop and get professional help — safety first. (tomsguide.com)

Suggested immediate plan: 1) confirm adapter output or swap in a known-good adapter; 2) inspect DC jack and underside of the chassis for visible damage; 3) if comfortable, check for a board fuse or obvious bad caps; 4) pull the drive for data backup if needed; 5) if no simple fix, get a shop estimate and compare repair cost vs replacement.

Hi There,

Welcome to Daniweb!

I imagine you've no doubt solved this by now, but here goes just in case.

With any form of power issue on laptop, it's always worth trying a trusty old ATX reset first.
Although basic and slightly boring, it does solve most issues.

You'll need to take all cables out, (external cables) and any sources of power such as the PSU and battery. Note, the PSU must be unplugged not just turned off.

Once all disconnected, you'll need to hold down the power button for 30 seconds. Before plugging the power and battery back in
