Question about Compaq Presario CQ60-220US PC Laptop
I have a compaq presario CQ60 model laptop. my screen is completely black, theres no back light at ll. i had this problem earlier and had a wrranty, but my warranty hs now ran out. ive tried everything, ive took out the battery, pushed down the power button for 60sec to get rid of discharge, and still it did not work. also let the battery completely die, take out the battery, hold down power button and turn it back on still did not work, i have done this countless times. please help
If the computer starts and the fan are working ..but it seams to be in a loop and only make a click noise and do not boot..this is a issue with the Ram memory and it supposed to take it out and insert it again and give it a try ..if it does the same and you have 2 ram units ..take one out and try them one by one ..and see if one of them is burned.....also you can open it and remove the bios battery for a few seconds to make it see the hardware again ...
If it only has a power monitor light on ..but it do not start at all..it is the Cpu ..and again ..try to see if removing the Bios battery does a difference or replace the cpu ..
If it start s and seam to boot in windows...(hear the log on sound) ..but only the monitor is black ..than try to connect to an external monitor to see if it is a physical issue with the lcd screen or reinstall the operating system ...but if the reinstall is required it is supposed to show you the devices but black out when windows log in ..
anyway with what you told me so far ..I can not figure but suppose..and if it has power and seams to go on with just the fan noise..and a clicking sound ..it si a issue from a sudden power lost and removing the bios battery will fix it ..
