    Thanks. As it turns out, it was necessary to remove all four screws, two at the top and two at the bottom, in order to get to the battery.

The battery is located in a compartment next to the thumb wheel! Undo a small Philips head screw and slide the battery compartment down to reveal the SR44W (357) battery!

Resetting the CMOS password on an Acer Aspire laptop is much more difficult than resetting the password on a desktop.
Disassembly steps vary from model to model, but on most models, you'll have to take apart the computer to access the CMOS battery.
Don't take apart the notebook if you don't have experience disassembling PCs.
After turning off the computer and disconnecting the AC adapter, take out the battery (different from the CMOS battery).
All visible screws must then be removed from the bottom of the notebook.
Remove all components stored to their separate compartments on the base of the notebook.
Turn over and open the PC. Lift up the switch cover and remove the screws securing the keyboard to the PC, if any are visible.
Remove the keyboard.
Remove the screws securing the monitor to the hinges, and then set the monitor aside.
Disconnect all visible cables connected to the motherboard; and then remove the screws from the top cover.
Remove the top cover to reveal the motherboard. Locate and then remove the CMOS battery. Leave it out of the notebook for 24 hours; then reinstall it and reassemble the Acer Aspire.
Other Options
If removing the CMOS battery fails to clear the password, or if you dont feel comfortable with the idea of opening your computer, you might be able to gain access to the computer using a backdoor password.
These special passwords were implemented to allow technicians to access locked computers. Not all models recognize backdoor passwords.
Most Acer Aspires use the Phoenix BIOS, and backdoor passwords for this BIOS include BIOS, CMOS, phoenix and PHOENIX.
All of these passwords are case-sensitive.

The power button in my Gateway laptop MT6451 got pushed it can't be accessed from the top. How can it be accessed from the button?


Quite easily Sergio

The plastic Power On button you see, presses against a carbon button Power On switch, below it.

I suggest removing the Switch Cover, and then you can access the Power On switch's carbon button, and press it down to turn the laptop on.

You can also, then see about repairing the Power On button assembly, or replace the Switch Cover.

1) Remove ALL power. Remove the AC adapter {Charger}, and Battery.

2) Laptop closed, laid on it's top; Bottom side up.
Turn it so you are looking down in the Battery Compartment, where the Battery was......

Down in the Battery Compartment are 4 Philips head screws to remove. You need the smaller No.1 Philips screwdriver, or the equivalent Jewelers screwdriver.

Here is the Base Enclosure, (Bottom Cover), not installed on the laptop,

http://www.ebay.com/itm/39MA7BATA10-Gateway-MA3-MT6451-Bottom-Case-Cover-39MA7BATA10-Genuine-/321101430142?pt=LH_DefaultDomain_0&hash=item4ac322fd7e

There are 4 views. The page automatically opens, with a Bottom view, and the Battery Compartment at the top.

SET, your mouse cursor in the middle of the photo. This allows the Zoom In feature.
Go to the top where the Battery Compartment is, and view the 4 holes going along the Top.

This shows you where the 4 screws to be removed are.

Same design, different Gateway notebook,

http://www.insidemylaptop.com/remove-keyboard-from-gateway-mt6704-model-ma7/

Go to the third photo down. Has two screws circled in Red.
I just want you to look at the Battery Compartment. (Not the red circled screws)

Look under the whitish - www.InsideMyLaptop.com -
You can see the first two screws pretty visibly. Almost make out the 3rd one, no to the 4th screw.

Once these 4 screws are removed, turn the laptop over.
Open the laptop.

Now you are going to remove the Switch Cover.

In the above link scroll down to the 5th photo, and 6th photo.

This video also shows you,

http://www.youtube.com/watch?v=KjOVOLOW1Hc

From 0:45 to 0:47
Please use care when removing, it is plastic.
The video has been sped up.

This is a look at the Switch Cover removed,

I cant find the break fluid resevoir in my ar i have an audi a4 1.8 liter manual 4 door 2003


look under the plastic cowl that's in between the windshield and the engine compartment. There will be an access panel for the battery and just to the drivers side of that there will either be an access for the reservoir or a whole and the reservoir cap will be visible in it.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Where can I find my jumper to reset my bio password on my hp computer?


On the edge of the motherboard - Most jumpers are located on the side of the motherboard for easy accessibility, verify by looking at all visible edges of the motherboard.

By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual cmos battery.

By the processor - Some manufactures will place the jumpers by the processor of the computer.

Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.

Other visible location - While it is possible that the jumpers / dipswitches may not be in a visible location, most manufactures try to make things easier by placing the jumpers / dipswitches in another visible location.

If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.

On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.

If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.


hope this helps

HannStar J MV-4 (jumper clearcmos/reset bios) password initial wrong setup bios heeeeeellppp.


The location of the jumpers or dipswitches may vary; however, here are some locations of the jumpers / dipswitches.
  1. On the edge of the motherboard - Most jumpers are located on the side of the motherboard for easy accessibility, verify by looking at all visible edges of the motherboard.
  2. By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual CMOS battery.
  3. By the processor - Some manufactures will place the jumpers by the processor of the computer. However, note that in some cases these jumpers will be to change the processor and not the password.
  4. Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.
  5. Other visible location - While it is possible that the jumpers / dipswitches may not be in a visible location, most manufactures try to make things easier by placing the jumpers / dipswitches in another visible location.
  6. Jumpers may also be found underneath or allongside the memory modules.
I hope this helps but suggest that the manufacturers web site or your instruction manual, may have the answer.

No Sound/No Power


I used your site to research the problem further. I found an answer which recommended rubbing the suspect terminal lightly with a pencil eraser. It worked! I now have battery power and my headset works fine.
