Hello, I have a Gateway laptop, I have not powered on for about 3 yrs due to screen being broken, now that I repaired the screen it will not power up. Ive tried all your solutions and nothing. Please help!!!
If your laptop is old say about more than 3 years and showing no power symptom then you should Check the power cable connection coming from SMPS to Motherboard as well. check the cables of your computer. Check the cable of Hard Disk connecting to motherboard and also check the RAM slots whether RAM is properly inserted. In case of loose RAM, your CPU box will lay a beep sound. Check the power cable connection coming from SMPS to Motherboard as well.
