Compaq tech support is certainly correct it is a hardware problem. So what could it be? You didn't supply much information. It is most likely a power supply problem. First thing to check is the brick power supply. It could have failed and the laptop would run until the battery goes dead. Get another power supply to check this. Then check the battery. It could also be the switch. If it is the internal power supply, follow the advice the computer shop gave you. It wouldn't be the hard drive, as it should at least start to POST with a bad HD. On behalf of the computer shop let me say that troubleshooting these types of problems on laptops is time consuming and usually not cost effective for a laptop this old.

At one point, it will not even power on. I went to the Tech Support on-line help with Compaq and was told that I have a hardware problem. Just recently, I tried to power it on again after a couple of days and it did come up. Then while I was working, it suddenly shut off completely and will not come back on. Where can I start troubleshooting this problem. Is it a hard drive probem? or something else. I tried to take it to a computer shop and their advice was that it is cheaper to buy a new laptop. They tell me this without even looking at my laptop. All I told them was that I have a problem, and didn't even get to finish explaining myself and suddenly they just told me to buy a new one. I've had this laptop for 4 years and I think I can fix it with a little help. Can you help me? Thanks!
