You don't need to remove the main battery to install or remove thr RAM module/s
The RAM module/s will be located behind a panel on the bottom of the laptop on most laptop models.

Sony vaio pdc-8x2l disassembly

The cover above the keyboard might be secured by screws inside the battery compartment. Just remove all the screws from the bottom of the laptop, but check inside the battery compartment, hard drive compartment, dvd drive compartment, memory compartment and wifi compartment for screws once you remove them or remove the cover.

I didn't open my Toshiba satellite l510 laptop because of BIOS password.

Hi ashisbd

If it is a Password holding you up at POST and the Laptop will neither go into BIOS nor Boot at the POST Screen, then the only way around this is to either enter the correct password of to dismantle it and disconnect and reconnect the CMOS battery inside, reassemble the laptop and then try again (see images below for a typical CMOS Battery Access and a typical CMOS Battery).

In some laptops there is an extra level of security for BIOS Passwords. The BIOS password is stored on a subsidiary chip rather than the main BIOS Chip and disconnecting and reconnecting the battery will not work.

I hope this helps.

I cannot find the memory slot to add extra ram into my asus x5dc

There are 4 screws on the rear(2 either side of the hinges),remove these screws.With the bottom of the laptop facing up then remove the battery cover(should already be removed along with power supply and battery),there should be 1 shorter screw in the corner of the battery compartment,remove this.The full bottom panel should be slid towards the rear just under an inch.The panel should then just lift of revealing the memory slots.Hope this helps.

How to add memory

Before adding or changing memory modules, shut down the computer, unplug the adapter and remove the battery to prevent accidental turn-on.

There are two memory sockets on this model. The easy one is on the bottom. Look for a panel held in place with a single screw, 3 3/8" x 2 1/16" (86 mm x 52 mm). Remove this panel (it has a captive screw, so you only have to turn it until you can lift out the panel). If there is a memory module already installed, unlatch it by pushing the two metal spring clips on the ends away from the memory module. The module should pop up a little bit and you can lift it out. (Handle memory modules only by the edges. Do not touch the circuitry!) Place the new module into the socket, then push it down until the spring clips latch. If you can't get both latches in place, you don't have the module seated properly.

The hard module to get at is under the keyboard. First remove the single screw in the center of the battery compartment. Open the computer and carefully unsnap the trim strip between the keyboard and speaker bezel (this was secured by the battery compartment screw). Now remove the two screws next to the F1 and Windows keys. Lift the keyboard slightly at the back, then carefully push it towards the back just enough to clear the six tabs at the front (by the right and left arrow keys, the Delete, space bar, ` and Control keys). There is a delicate ribbon cable attached near the front of the keyboard. It is not necessary to disconnect it. Lay the keyboard upside down over the touchpad. Now you can get at the upper memory module socket. It works the same as the lower socket.

Blank screen on laptop

Sorry to hear you are having problems. I have had this same issue before with this particular model. The following solution works 90% of the time.Perform a hard reset as the first procedure.
  1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
  3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
Meaning of Sample Blink Codes for some EFI Notebooks Number of Blinks or Beeps Location of Blinking LEDs Component Being Checked Error Condition Continuous glow Battery power LED Battery The AC adapter is attached and the battery is charging, but does not yet have sufficient charge to power the notebook. 1 Caps Lock/Num Lock CPU CPU not functional 2 Caps Lock/Num Lock BIOS BIOS corruption failure 3 Caps Lock/Num Lock Memory Module error not functional 4 Caps Lock/Num Lock Graphics Graphics controller not functional 5 Caps Lock/Num Lock System board General system board failure 6 Caps Lock/Num Lock BIOS BIOS authentication failure Continuous blink AC power adapter LED Power adapter Insufficient power
Blink codes are often displayed after a user adds memory to the computer but does not seat the module properly. The LEDs may also blink error codes if a hardware component is loose because the computer was dropped or jarred. Some HP Notebook PCs come with one stick of memory but have two memory slots. The problem could be that the stick of memory or one of the memory slots has a bad connection. The memory module compartment on most notebooks is located on the bottom of the case. The exact position varies by model. However, on some models, the memory compartment is under the keyboard. See your User Guide for the exact location of memory modules on your notebook.

Use the following steps to remove and reseat the memory modules: Step 1 - Remove the electrical power To remove all power from the computer and prevent accidental damage to the electronic components, do the following:
  1. Turn off the computer by pressing and holding down the Power button for about 30 seconds.
  2. Unplug the AC adaptor from the notebook.
  3. Slide and hold the battery release latch to the unlock position.
  4. Use your finger to lift the battery up and out.

  • Remove the memory module cover on the bottom of the notebook .Loosen the compartment's retention screws and lift up and remove the memory compartment cover. Remove the memory modules from the memory slots To prevent damage to the memory module, grasp the memory module by the side edges. Do not touch the metal contacts.
    1 - Pull the retention clips away from sides of the memory module
    2 - Gently pull the module out of the memory module slot
  • Reseat the memory module by holding module at a 45-degree angle, and pressing it firmly into the memory slot until it is seated.

    After reseating the memory module, replace the cover over the memory compartment before restarting the computer

    Hope this helps FiYa! If you find this solution helpful, please take a moment to leave us some feedback.

    How do you get the door open to install a battery in the satellite 1415-S173? I need to add more memory and I was told to first take out the battery. I can't get to the battery.

    Hello !

    Your laptop battery should just slide out. You may be thinking of the CMOS battery (silver, round battery). The external battery is easy to remove and it needs to be removed first.

    Hope this helps.

    I'm trying to upgrade memory in a compaq presario m2000 laptop. Was told it would be obvious and easy but looks tough to me. Can you help?

    1. Save your work and close all open applications.

    2. Shut down the notebook.
    If you are unsure whether the notebook is off or in
    hibernation, turn the notebook on and then shut it down
    through the operating system.

    3. Disconnect all external devices connected to the notebook.

    4. Disconnect the notebook from external power.

    5. Remove the battery pack.

    6. Turn the notebook upside down.

    7. Loosen the 2 memory compartment screws (1), and then lift
    up and remove the memory compartment cover (2).


    8. Remove a memory module.
    To remove a memory module:

    a. Pull away the retention clips on each side of the
    module 1. (The module tilts upward.)

    b. Grasp the edges of the module and gently pull the module
    out of the memory slot 2.

    c. To protect a memory module after removal, place it in an
    electrostatic-safe container.


    To insert a memory module:

    a. Align the keyed (notched) edge of the module with the
    keyed area in the memory slot 1.
    If you are inserting a single memory module into a vacant
    memory compartment, insert the module into the lower
    slot. (The following illustration shows a memory module
    being inserted into the second slot of a memory
    compartment that already contains a memory module.)

    b. With the module at a 45-degree angle from the surface of
    the memory compartment, press the module into the
    memory slot until it is seated 2.

    c. Push the module downward until the retention clips snap
    into place 3.

    9. To close the memory compartment, align the tabs on the
    memory compartment cover with the cover slots on
    the notebook, and then slide the cover over the memory
    compartment until it is seated 1.

    10. Tighten the 2 memory compartment screws 2.


    11. Replace the battery pack, reconnect the notebook to external
    power, and then restart the notebook.

    Hope this helps. If you need anything else, don't hesitate to ask. Also, here is the manual for your machine with more instructions. Pretty handy.

    Happy Holidays!
