To Guest : You have joined the realm of goosed motherboard

power supply? check and re-check connections (hard drive, cpu power cord, main connection to motherboard).
its your memory listed under the "memory support list" of your motherboard manufacturer?.
if not listed, contact the manufacturer (motherboard and memory) to make sure that they work together.

if none of these works, you have a bad motherboard. Good Luck

Instructions

1

Prepare the laptop for disassembly. Shut down the laptop completely, then wait a few minutes before removing the battery and unplugging the AC adapter.

Disconnect the motherboard. Lift the system board, then unhook the cable connecting it to the base unit.

Turn the laptop over and remove the battery pack.

From the bottom of the laptop, unscrew the plastic shells securing the slots for memory,

Bluetooth, hard drive and modem.

You may have to remove more than one screw for each shell. Keep all screws in a small container, away from the work area.

Remove the memory (RAM) modules, the hard drive and any optical drives (CD-ROM or DVD-ROM).

Press the clips on either end of the memory slot to raise the RAM module and detach by pulling it out. Work slowly and carefully, to prevent damage to RAM modules or the memory slot.

Do the same for all modules, if you have more than one.

Slide out the hard drive and optical drive. If the drives seem to be stuck, look for any screws you may have missed.

Turn the laptop over and insert a pointy tool under the thin strip at the top of the keyboard. Use the tool as a lever to pry the securing strip loose, while working with your finger to release latches along the length of the strip.

Remove the keyboard by undoing two screws securing it.

Raise the keyboard and disconnect its cables.

Close the laptop lid and turn it around, so that you are facing ports on the back.

Remove two screws from the metal plate around the ports.

Open the lid and remove a single screw securing the wireless card cover; the screw is under the keyboard, which you already removed.

Disconnect cables from the motherboard.

Access the board through the space created by removing the keyboard. Unplug the speaker cable from the motherboard by carefully pulling at its head.

Unscrew and remove Wi-Fi antennas, and detach the wireless card from the motherboard. Unplug thin, ribbon-like cables from the video card.

Detach the display assembly from the base of the laptop.

Loosen any attachments, and pull the casing toward you to detach the display assembly, including the LCD panel, from the base.

With the motherboard completely exposed, unscrew and remove the video card.

Undo two screws from either side of the hard drive housing and detach the drive.

Dismount the CPU heat sink and detach the fan cable from the motherboard by removing five screws.

You can now access the battery board with the CMOS battery attached to it.

Undo two screws to detach the battery board from the motherboard.

Disconnect two cables running from the battery board, and carefully raise the board to detach it.

Replace the CMOS battery by prying it open with a pointy tool. Insert a new battery and reassemble the laptop.

hope this helps

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper

The most common way that most of us know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing a battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off the battery power, the BIOS/CMOS settings will be erased.

You dont need a extras Hard drive That someting else .. Hard Drive and Memory are two differente Thing... Go on the Net and Exemple... Type Compaq Presario SR1802HM.. Manual & Spec, You will get all the information your need for it ....

Remove everything from the board except the front panel hookups.Make sure you remove memory, video card, hard drive and cdrom cables, hard drive and cdrom power, anything plugged into the back except the power. If it will power up this way start plugging things back in between power cycles. Start with memory then power down. Then add video then power down. Continue with Cdrom, then hard drives. When it stopps wanting to power on you know where the issue lies. If it wont power on with nothing on it then the motherboard is probably bad. Hope this helps.

Try this:
STEP 11
Lift up and remove notebook display panel.
STEP 12
Remove hard drive cover, memory cover and modem cover from the bottom of the notebook. Each cover is secured by one screw.
STEP 13
Here’s how you can remove the hard drive. Remove four screws securing the hard drive caddy to the base assembly. Slide the hard drive down to disconnect it from the motherboard. Lift up and remove the hard drive.
STEP 14
Removing memory modules (if needed). Carefully spread latches on both sides of the memory slot. The memory module will pop up at 30 degree angle. Pull the memory module from the slot by the edges.
Removing modem card (if needed). Remove two screws securing the modem card. Lift up the modem card to disconnect it from the motherboard and unplug cable from the side.

Hope this Helps
