I have this laptop, and whenever I press the power button it lights up. Then when the windows loading screen would pop up, it is just a pure black screen (no line for the bios boot up). And then it freezes there. I managed to turn it on today, and I ran a virus scan and removed the viruses I found. Then the computer restarted, and it doesn't boot up again. When I press the button there is no beep (but I am not sure if this applies to laptops as well). When we turned it off when it was functional there was a high pitched power down sound, but now there isn't even that. what could be the problem? Another note is that it was a progressive thing. It didn't just not boot up from one day to another.

Short, practical troubleshooting to narrow this down (based on ’s description and ’s suggestion to try BIOS/USB). Because the machine never shows firmware/POST, the fault is very likely hardware (display, memory, power rail, GPU or motherboard) rather than just the Windows boot loader. The steps below go from safest/simple to more intrusive; stop at any step you’re not comfortable with.

  1. Power-reset: remove battery and AC, hold the power button 30–60 seconds, reconnect AC only and try power on. This resets the embedded controller and often clears odd power states.
  2. External monitor: plug a VGA/HDMI cable to a TV or monitor, power on, and use the laptop display-toggle key (Fn+whatever). If the external shows BIOS/POST, the internal panel or its cable/inverter is the problem.
  3. Bright-flash test: in a dim room, shine a bright flashlight at the screen at an angle while powering up. A very faint image means the panel is displaying but the backlight (inverter or LED) is dead.
  4. RAM check: reseat modules, try a single stick in each slot. Bad/loose RAM can stop POST; some laptops won’t beep even when RAM fails.
  5. Bare-minimum boot: disconnect HDD/ODD and any USB devices, try powering with AC only. The firmware should still show; if it does, the problem could be the drive/boot chain.
  6. Note power signs: fans spinning, drive LED activity, any error LEDs or beeps, and any unusual sounds. Record them for the technician.

If external stays blank and no POST after the RAM test, suspect motherboard/GPU or the DC/power circuitry. Do not attempt BGA reflow at home — it’s a workshop repair and temporary. If data is important, remove the hard drive now and copy it using a USB-SATA adapter before sending the laptop for repair. Opening the case can void warranty and risks ESD damage; if unsure, take the laptop to a reputable repair shop and give them the model, what you did above, and that the failure was progressive and began after the recent virus/scan.

Can you boot into the BIOS, recovery partition, or diagnostics? What about booting to a USB drive or CD/DVD disc?

I have not tried booting to a usb, although I doubt I will be able to. The bios and such do not show up at all.

Then I suspect you have a hardware problem. Time to take it to the shop for diagnosis and repair.

It may be, though when I came home today and pressed the power button it turned on. While yesterday it barely managed to.
