I am at a loss, this machine will not power on or charge the battery, when it is plugged in to the adaptor the light under the litte picture of the plug in flashes and the blue light on the adaptor flashes. Sometimes the display screen or other lights will flash but it will not start. :cry:

The symptoms described by and the power-focused reply from point to a fault in the laptop's power delivery path. The following is a concise, ordered checklist and repair/data-rescue guidance to isolate the fault safely and avoid unnecessary expense.

  1. Safety and quick checks: unplug and remove the battery before opening the case. Inspect the DC jack, adapter cable and battery for physical damage or swelling.
  2. Verify the adapter with a multimeter: read the adapter label for expected DC volts and polarity, set the meter to DC volts and probe the center pin (positive) and outer barrel (ground). A stable voltage near the label value is expected; intermittent or zero output points to the adapter. If the adapter reads correctly but the laptop forces the adapter LED to blink, the laptop is likely drawing a short/current fault.
  3. Wiggle-test the barrel while watching the LED and meter: fluctuations usually indicate a loose/broken DC jack or a cracked solder joint.
  4. Open the chassis for a visual board check: look for cracked solder, burned components or swollen capacitors around the DC-in area. With the battery removed, use an ohmmeter to check any obvious input fuses or MOSFETs for opens/shorts.
  5. Minimal-boot and diagnostics: reseat RAM and try powering with only the adapter connected. Count any LED blinks/beeps and note the pattern for model-specific diagnostics.
  6. Repair vs. data rescue: if the DC jack/solder pads are bad, replacing the jack or reflowing the joints is often cheaper than a full board swap. Before any board-level work, remove the hard drive and recover data with a USB adapter/enclosure if data is important.

Do not use an adapter with incorrect voltage or reversed polarity. If uncomfortable with solder-level diagnostics, get a bench test from a reputable shop and ask for a written failure report before authorizing a motherboard replacement. Document meter readings and blink patterns — that information greatly speeds accurate diagnosis.

Your power adapter is probably dead, try finding someone with the same adapter or go buy a new one that is compatible. If it is not the adapter, the power connection to your motherboard may have become lose. This is an easy sodering fix, but most places just replace the motherboard. If its not the adapter, and the cost to repair is over 100 dollars, I'd look into buying a new laptop (especially if it is older).
