When i power on my laptop all led's stay lit and there is no drive activity,, infact there is no acyivity at all the only way to power off is to remove the battery.....
First of all, you should never have to remove the battery to force a shutdown. On most laptops (including the latitudes), you can hold the power button down until it shuts off - usually takes 5-10 seconds.
Also, we need more info. Does it work with an AC power supply connected to it? Try the AC without the battery. Remove all peripherals (CDROM, Floppy, Modem/LAN card, etc.) and try to power it on from AC. This should at least get you to the BIOS screen.
- take out hard drive, floppy, cd-rom, battery and tried it on AC
- hold down power button for up to 20 secs until LED lights go off
If so, try this:
1) tighten all screws underneath the laptop (the center one acts as a grounding screw and must be securely in)
2) with everything out of the system (peripherals, HD, etc.) and power disconnected, hold the power button down for 30 secs which forces an internal reset
