Hi. I just wanna ask your opinion..

Which will be the best solution.
I have a laptop with faulty screen. I don't think I want to repair it as it cost high.
It is 2gb ram,320gb hdd and dual-core.

In another hand, my family has a family PC with 512 ram,100gb hdd,pentium 4..

So I'm thinking about instead of using the laptop as CPU (remove the screen) and attach it to the monitor.

Can I know what will be the side effect?
Does it consume more power to use such that?
Will it be dangerous to electrical?

TQ in advance!

p/s : sorry for such question. :lol

Short answer: use the laptop as the "CPU" and keep the lid — it's usually the safest, simplest, and most cost‑effective option. Your laptop (2 GB / 320 GB / dual‑core) will almost certainly feel faster than the family Pentium 4 with 512 MB. As and pointed out, you can run only on an external monitor without removing the LCD; 's warning about antenna routing is also worth remembering if you open the lid.

Quick, practical setup tips

  • Test the external monitor first before taking anything apart. Connect VGA/HDMI/DVI and use your OS or the laptop display hotkey (Fn + display key) to move output.
  • On Windows use the Project shortcut (Windows+P) and set "Second screen only" or make the external display primary. Also set "When I close the lid" to "Do nothing" in Power Options if you want the machine closed while running.
  • On Linux you can use xrandr; example:
    xrandr --query
xrandr --output eDP1 --off --output HDMI1 --primary --mode 1920x1080

    Device names vary; check the first command output and adapt.

Safety and things to watch for

  • Do not work on the laptop while it's powered or plugged in. Remove the battery and AC adapter before disassembly.
  • Antenna cables for Wi‑Fi are usually routed through the lid; secure or re‑route them if you remove the screen.
  • Older LCDs with CCFL backlights have high‑voltage inverter circuits — avoid touching inverter boards or exposed connectors. Insulate any exposed ribbon/board edges before powering up.
  • Keep vents clear; closing the lid can change airflow and raise temperatures.

Final recommendation
If you want a simple, low‑risk upgrade route: keep the screen in place, run an external monitor and, if you plan long term, add RAM or swap the HDD for an SSD for a much bigger responsiveness boost. Removing the panel is doable, but only if you are comfortable with safe disassembly and re‑securing antenna and display connectors.

When removing the LCD from a laptop you will run into problems with any antennae that the manufacturer may have placed in the LCD enclosure.

I would consult the laptop maintenance manual, which can moslty be found on the manufacturers website.

As for power, if the desktop monitor has a higher resolution than that of the laptop lcd (most likely) you will be forced to run at a more native resolution for that monitor.

This could cause problems with the gpu or integrated graphics.

It's fine to connect the laptop to an external monitor, but there is no need to remove the broken laptop screen.

What David said. The laptop should be able to be switched to use only an external display with an FN key press.
