My daughter's Compaq Presario 1700 laptop (model #17XL4) won't start.
It had been working fine on battery when she noticed the battery was getting low. She plugged in the A/C power adaptor and the system immediately shut down. The documentation with the laptop says this should not be done while the comp is turned on, and she forgot.
Now, when attempting to power up, the hard drive starts to spiin, the screen shows a wash of backlighting, which I think indicates that it is getting power but no signal. There is no post beeps and the fan doesn't start spinning.
Some other posts on this site say that if the fan doesn't start, then the laptop will not post. Some others say that the fan only spins when needed. I am not sure but suspect the motherboard, power supply regulator, CPU or memory may be fried, but don't know how to track down the problem. I have checked the hard drive in another comp and it works fine.
Can you suggest where and how to look next? Or, is this a deader?
