Re: Computer won't start
Well this is an easy one.... Provided you know for a fact that your battery is good, then the answer is that you have a fault on the hardware side of the board. There is so little to check on the battery side that it may be that you only need to replace the battery contacts on the motherboard (tho it is a rare failure). If not then its the motherboard that has failed. This CAN happen if you have kept a failed battery in the laptop too long which then fries the

The first thing to check is for proper power. Try connecting your charger with the battery removed and powering up the computer. If you are not successful with this, it may be that the charger is defective and not charging your battery. Advise that you purchase/borrow a supported laptop charger. A local HP repair center should have a compatible charger that you could use to test. If it is not the charger (the laptop should work without a battery), then you have motherboard problems. Memory or other issues would cause a power on but errors. No power up at all is going to require some sort of board replacement. At that point, your choice is warranty repair service or, if out of warranty, best bet will be replacement of laptop.
If you want to keep your important data, use some softwares can solve thewindows won't startproblem most quickly, and no data will lose. Besides, it is very easy, even the people who lack of computer knowledge can deal with windows won't boot issue.
IF the system is not turning on any more, try removing the power cable, then press the power button for 10 seconds. then try to power it on again . If it is still not powering up there could be an issue wiht the power supply of the computer. But if it start to turn on, like showing the Sony logo then windows but not going to the desktop. you can try to log on using safemode. you can go there by pressing F8 on the keyboard after turning on the computer. If it still not turning on even on safe mode. there couldbe an issue with the operating system of the computer and needs to be reinstalled.

The charger is functioning well. There are still two possible reasons why your computer is not turning on. 1. The battery, 2. The computer itself.
What you need to do is to isolate the problem.
Here's what you can do to isolate the problem.
1. Remove the battery from the computer. 2. Turn on the computer using the cord. Remember not to put back the battery yet. Just the cable and the computer connected. If the computer turns on, then, you need to replace the battery. 3. If it still not turning on by using the cord alone. Try to wiggle the cord to check whether it's loose or not. Check if there are some signs of power on the computer. If there is a power like lights lit in the computer, then, it's the computer that's having the problem. You need to bring it to a technician if that's the situation.
Please let me know if there are any development after doing the troubleshooting above so that I can get back to you if you need my help.
There could be a problem with the battery. A fast check to determine whether you have a problem with the power
adapter, power cord or the laptop's battery is to turn off the laptop,
remove the battery, connect the power adapter, turn on the laptop &
see if it works.
If the laptop works directly from the power adapter
with the battery removed, then the power adapter is good. In this case
we can suspect that the battery is defective & needs to be replaced.
If this did not work, try also disassembling the laptop & make sure
that all main components are seated properly. Also make sure that all
ribbon cables interconnecting the various components of the laptop are
Consider NOT connecting your camera to your computer.
The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.
Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use iPhoto or any other photo cataloging program.
1. Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the computer on, and then shut it down through the operating system. 2. Disconnect all external devices connected to the computer. 3. Disconnect the power cord. 4. Remove the battery pack by following these steps: a. Turn the computer upside down with the front panel toward you. b. Slide and hold the battery release latch 1 to the left. (The front edge of the battery pack disengages from the computer.) c. Lift the front edge of the battery pack 2 and swing it back. d. Remove the battery pack. 5. Remove the RTC battery from the socket on the system board. 6. Wait approximately 5 minutes. 7. Replace the RTC battery and reassemble the computer. 8. Connect AC power to the computer. Do not reinsert any battery packs at this time. 9. Turn on the computer. All passwords and all CMOS settings have been cleared.
