Hi @RAFIK09 Do any of the lights flash if so which ones and how many flashes? Have you tried looking at the screen with a torch/flash light to see if you can see anything. If you do then either the brightness control is set very low or the backlight is not working. Another thing to try is connecting the laptop to a monitor or TV to see if there is a display. If that works then either the screen is defective or the ribbon cable from the motherboard to the display is loose or defective.

There are commercial plastic polishing compounds. They come in various grades. I used them when I worked to refurbish electronic communications equipment for the disabled. Don't expect perfect results and work slowly and gently for best results. Here is one example, which is NOT an endorsement just to give you an idea of what is out there.: https://www.novuspolish.com/ Remember it is best if you contact the manufacturer yourself. Tell them what you are trying to polish and they should recommend their best product for that plastic. Use your own judgement. If they are too positive be wary.

Take it back to the person that "repaired" it. They obviously stuffed it up.

@cindy559 Hi Cindy, Can you hear the fan or the hard drive spinning ? If yes then it is powering up O.K. If you are adventurous this video https://www.youtube.com/watch?v=4qDGFsXa... shows how to open the case to allow you to take out the CMOS coin battery to reset the BIOS. You will see it just above the RAM module. Make sure it is unplugged and turned off before you attempt anything. Take your time and watch the video several times and be gentle. With the coin battery out press the power button (don't plug in power!) and hold for 30 seconds to reset. If you carefully balance the screen you can test it before reassembling. It could take more or less 45 seconds before you see the screen come alive. So wait and be patient. If that fixes it while it is open you could also upgrade the RAM and replace the hard drive with an SSD drive for a much faster system.

This Netbook has two GPU's and it may be something to do with the fact that Asus decided not to equip this netbook with Nvidia's Optimus technology, which allows notebooks to automatically switch between Intel's integrated graphics and Nvidia's Ion GPU. Instead, you're forced to use the included Asus GraphicsSwitch to manually change modes, which requires a reboot. The Nvidia Ion GPU gives HD video playback on a big-screen monitor or TV via the netbook's HDMI port so this may be what the projector is expecting??? Any how give it a go and tell us if that helps.

As there are no schematics available. and you also would need to do micro soldering, which is a specialised skill, why not just purchase a seperate external SATA drive enclosure. Personally I avoid these WD, Seagate, etc. with their proprietry connectors (yours is old so still uses standard SATA) and firmware. Incidently there is freeware software that allows you to read LINUX disks in Windows.

Is Windows and all drivers up to date? Corrupted drivers can cause strange responses. Run DISM.exe or DISM Image Servicing Utility file to fix the system image. It is a little involved and takes a while to explain so check out the following or other sites to explain how to run it in detail: https://www.windowscentral.com/how-use-dism-command-line-utility-repair-windows-10-image. There are a number of "switches" to use. Run SFC /scannow or System File Checker (SFC) command tool to repair the current Winodws setup. Open Start and Search for Command Prompt (CMD), right-click the top result, and select the Run as administrator option. Type the following command to repair the installation and press Enter: SFC /scannow If you find errors run it again until no more errors are found. The above will generally eliminate software errors. Let us know how it goes. Run Check Disk (1) Type cmd in the search box of Windows 10 and right-click the Command Prompt to choose Run as administrator. (2) Type chkdsk /r command in...

Here are some ideas. Check them out and let us know how it goes. First thought sounds like a video driver issue. If that is the case uninstall the driver in Device Manager and reboot the laptop and let Windows reinstall the driver. Another thought is that it is set to external monitor. This is easily checked by connecting a TV or external monitor during the first powering on. Then look on your keyboard for the Function key for internal/external screen setting.

When the LED is green the battery charge is between 95% and 100% and the AC power is on. The orange/amber LED indicates that the battery power is below 95%, and the AC power is on. Without the charger plugged in an orange/amber blinking shows the battery charge is below 10% and needs a charge. However, if your laptop battery percentage is above 10% and the LED keeps blinking orange/amber it may mean the battery needs replacing.

Might add “Optical” to drive title to save some confusion.

These name branded external drives are the worst possible choice. Always, always purchase a SEPERATE case/controller and hard drive. Again, why? Often the branded ones have the drive’s circuit board and the USB port imbedded in the same circuit board. If that circuit screws up you are often lost. The component solution (like a good hi-fi sound systems) allows you to easily take the drive out, if the USB part goes bad, and recover your software in another system or case. If the drive dies replace it or upgrade to SSD or larger capacity. A no brainer!
