I have tried doing a hard reset but it did not help. Instead, my screen is still balnk and the power light on the power button and my wireless light keeps blinking. The fan spins and then stops and this continues even after unplugging the laptop from the wall socket, removing battery, pressing and holding down the power button for 15s. After pressing and holding down the power button for 15-30s i connected the power adapter with and without the battery but still get the same results whereby the power light and the wireless network light keeps blinking and the screen remain blank.
I have disassembled the notebook, replaced heatsink paste and also removed bios battery from the board. i assembled the notebook and got the same results. i tried another memory module and power adapter as well but the same results was obtained. I removed the wireless adapter and hdd but the results are the same.
Any assistance will be highly and greatly appreciated.
