Hi,

There is strange problem occur this ester when i was working quite normal last night at my Dell XPS M1330 Laptop and did properly shutdown. After one hour when I want to work again I push the start button but strange thing occur that it shows blue light at start button and bettry place at the front but for 3 seconds and then disappear there is no anymore any screen display rather again shutdown without any delay.

I am using Windows 7 and I do not know what do do now. Because system is unable to start.
I have look over AC adapter it shows blue light with the battery light blue permanently while connected to power supply.

Please help me I have no experience with this Dell machine problem.

My main problem that this machine is not starting anymore even after pressing the start button further.

Thread originated from . Building on the hardware observations from and , the following ordered checks help narrow whether the problem is the AC adapter, the DC jack, removable components (RAM/HDD/display), or a motherboard-level fault — with a focus on low-cost, safe diagnostics before paying for board repair.

  • Power-discharge reset: remove the main battery and AC lead, then press-and-hold the power button ~30 seconds to drain residual charge. Reconnect AC (leave battery out) and attempt power-up. This often clears embedded-controller hangs.
  • AC-adapter check: try a known-good compatible adapter or measure the adapter’s DC output with a multimeter and compare to the label. An LED on the adapter does not guarantee correct voltage under load.
  • DC-jack inspection: visually check the jack for side-to-side play. If gently wiggling the plug while attempting power changes behavior, cracked solder joints on the jack are likely.
  • Minimal boot for POST: remove HDD/optical drive and boot with a single RAM module, testing each module and slot one at a time. A bad stick or slot can prevent POST without clear error messages.
  • External display test: attach a VGA/HDMI monitor to rule out inverter or LCD-panel/backlight failure.
  • Observe signs of life: listen for fan/HDD spin and count any front-panel LED blinks or beep patterns. Record exact blink/beep counts — these are key diagnostic clues.

Safety and next steps: always unplug mains and remove the battery before opening the case. Use basic ESD caution, photograph connections and keep screws labeled. If results point to the adapter or jack, those fixes are usually cheaper than motherboard replacement. If there are absolutely no signs of life after these checks, the fault is likely at the board level and a repair shop can confirm. LED/blink/beep patterns plus which steps produced what result are the most useful details for a technician.

Is it still under warranty? If so, get Dell to repair it.

No it not under warranty. It was a new machine I buy it second hand machine.
How I can find dell in Switzerland Zürich.

Kinldy write me.

Thanks in advance

That may be a problem. Those XPS machines are unreliable. I have a friend who is a Dell repair engineer, I will have a word with him the next time I see him.

Kindly tell me what should I do in this case?

Member Avatar for Rik_

Well, from what he has told me before about those machines, the 2 most common problems are motherboard failure and power socket failure. neither are cheap to get repaired.

You would be best getting it to a local computer repair shop for fault diagnosis.

Hi Mushak,

Do you see a light on the front of the machine where the battery is (the battery indicator light) when the power supply is plugged in?

If not then your power connector inside the machine is more than likely faulty.
This will need to be replaced (unsoldered from board, removed, & new one soldered in place), or you will need a new power supply.

Hope this helps.
