has done the right initial checks and was correct to suggest an external monitor. Because the machine powers (activity like DVD eject shows something is alive) but produces no picture, work through the following ordered checks to narrow the fault before spending on parts or a shop visit.

  1. Power-reset: unplug AC, remove battery, hold power 20–30 seconds to discharge, then try booting on AC only.
  2. Verify the adapter: confirm the adapter LED and, if possible, measure output with a multimeter or try a known-good adapter of the same rating.
  3. External-display retry: connect an external monitor, boot, then press the laptop display-toggle (Fn + display key) while cycling inputs on the external monitor.
  4. POST diagnostics: listen for beeps and watch keyboard LEDs; remove all RAM and power on to force POST/beep codes (helps indicate motherboard/CPU health).
  5. Reseat components: carefully reseat memory modules, remove HDD/optical drive and try booting with minimum hardware (battery removed, AC connected).
  6. Screen vs backlight check: in a dark room shine a bright flashlight at the LCD — a faint image means the panel/backlight or inverter is dead; no faint image plus no external output points toward motherboard/video-chip failure.
  7. Physical checks: inspect the DC jack for wobble and the display cable around the hinge for obvious damage. Take photos while disassembling if attempting this.

Cautions: avoid metal tools near the board, ground yourself for ESD, and stop if the case or screws look unfamiliar — a professional bench test is reasonable at this point if the above steps do not isolate the fault.

Hey
Have you got any hardware troubleshooting experience?
Did the mercer work while you had it and then 1 day stopped working or did you get it because it does not work?
Are you sure that the battery is still in working order
Let us know

I put the laptop on agen now,it seems to be going on but the screen does not display anything it stays black like its off.when i press the eject button on the dvd drive then it ejects so the laptop does go on just no picture,i assume its the screen.

It should have a monitor output on the back, try plugging a monitor into it.

In that case, you need to get it looked at by a professional.
