Blank Screen on start. No display
You need to replace the motherboard. When nothing comes on the display this means the bios on the motherboard is bad and the board and cpu need replaced.
HP Pavillion dv7, lights come on but screen is
First, open the back cover for the memory (with power and battery removed of course) and remove and re-seat the memory modules properly. Replace battery power and see if any result.
Second, try hooking unit to an external monitor to see if it is the computer or the just the screen giving issues.
If the monitor does not work, it is possible that the CPU could be at fault or the system board (possibly the built in video card) is faulty and this would need a new system board.
Display and Boot problem with HP Pavilion DV2125NR
It is normal for the bottom to get hot. The fan should keep it cool enough to run, but it sounds like perhaps your fan is not working very well anymore and should be replaced.
Does the computer act up at all when cool? If not, the first thing I would try is replacing the fan and examining the fan and heatsink assembly for proper installation, perhaps replace the heatsink compound with some Arctic Silver while you have it open.
How to fix hp dv2000 power problem
POWER SUPPLY & BATTERY PROBLEM If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods. When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.
