Averatec 3700 R1 Notebook - more RAM

How do I physically add RAM to my notebook? I removed the battery and access panel. The space under the access panel is filled with the cooling fan and copper heat shield. I can't see any place to insert an additional RAM chip. John

I don't know this notebook, but often you can remove the keyboard. Look for small catches at front of keyboard and use compass point to release front edge of keyboard.
If not there then see if panel above keyboard will slide across and release keyboard.
Sometimes screw(s) in base will release keyboard.

I forgot the cmos password .sony vaio model mbx 171


Hi

Sony notebook computers must be taken apart to reset the BIOS password to the factory default when the current password is forgotten or simply unavailable. A small battery inside the computer must be removed for a period of time in order for the password to reset. This requires notebook repair skills specific to Sony notebooks, and should only be attempted by a technician who is familiar with the process of taking Sony notebooks apart and putting them back together without damaging the parts.
Two way to remove BIOS password.

1) Soft reset 2) Hard reset
Soft Reset
BIOSpasswords can be reset in two ways,
1. using software 2. using hardware.

I would first try resetting using software, here are two software's to reset orretrieve BIOS passwords.

!BIOS- is a PC BIOS toolkit offering password removal/decrypt and BIOS settingsmodification/backup/restore.

CmosPwd- Cmos password recovery tools


Hard Reset


Step 1
Back up the hard drive to optical discs, an external hard drive or a network location to safeguard any important files. Step 2
Shut down the computer by clicking "Start" (Windows Orb) and choosing "Shut Down." Step 3
Disconnect the Sony notebook power adapter cable from the wall and from the back of the laptop. Step 4
Close the lid and flip the notebook over to expose the bottom screws and compartments. Step 5
Remove the main battery from the bottom of the Sony notebook. Step 6
Remove the compartment covers for the RAM and the hard drive. Step 7
Remove the hard drive by unscrewing the bracket that holds the drive in place and pulling gently on the drive until it disengages from the socket. Step 8
Remove the RAM by spreading the small metal retention clips that hold it into place, and then pivoting the RAM up slightly and pulling it out of the sockets. Step 9
Remove each of the small screws from the bottom of the Sony notebook, and place them on a clean, flat surface in a pattern that represents which hole each screw came from. Step 10
Gently flip the Sony notebook right-side up and open the lid. Step 11
Separate the base of the Sony notebook from the upper case by gently pressing the plastic knife or credit card into the seam and pulling the top away from the bottom. Step 12
Disconnect the wire that connects the small coin cell battery pack to the motherboard, or remove the coin cell battery from the socket, depending upon the model of the Sony notebook. Some models may require that the motherboard be removed from the case in order to access the battery. Step 13
Wait one hour with the battery disconnected and reassemble. The BIOS password will be cleared and the computer will boot into the BIOS setup program or to the operating system. This process does not clear any operating system passwords. Tips & Warnings
  • Reset a known BIOS password on Sony notebook computers by entering BIOS setup using the "F10" key on startup. Enter the existing password, and navigate to the security screen in the BIOS setup program to choose a new password. Consult the owner's manual for specific instructions on particular Sony models. Use a blank piece of paper to set the screws as they are removed, marking them or arranging them as necessary. It is important to replace the exact same screw into each hole that it came out of as there are often several different s of screws.
  • Notebook computers are assembled with small, delicate plastic tabs that are easily damaged. Internal cables and assemblies can be broken or damaged with relatively little force. Leave this technique to a professional technician if unsure of how to take a Sony notebook computer apart. Do not let the computer go into sleep or hibernation mode or simply shut the lid as this is not a full proper shutdown and the hard drive can become corrupted if the computer is not properly shut down for this operation.
Give me the thumb if you problem solve.

Hi! where will i find the cmos battery for my Lenova T400.


Believe it or not, Wamart has a pretty good selection of batteries at their jewelry and camera counters. You can also try a computer shop.
I tried to find one on the web, and was referred to the "manufacturer". Going there, I found a recall on some Lenova computers:

I do have a ASUS P5GC-MX/1333 REV. 3.05G Motherboard. Whenever I boot my computer it displays "Chasis Intruded" or "CMOS settings"..............and computer won't boot. How can I solve this


> chassis instrusion

Some computers can sense when some (presumably "unauthorized") person removed one of the side-panels from the computer-case, maybe to remove a disk-drive, remove a CD-drive, or remove a stick of RAM. So, your computer is just telling you that it has (sometime) sensed that physical access.

> CMOS settings

What's the _FULL_ text of that message?

It could be that the battery on the motherboard (silver-coloured, about the size of a US $0.25 coin) is "dead", and needs to be replaced.

How to install saound card for NEC versa E6200 for


Hi,

First off that notebook is not Windows 7 capable. Here are the WIndows 7 requirements:
  • 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
  • 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
  • 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
  • DirectX 9 graphics device with WDDM 1.0 or higher driver.
But, if you want to add a PCMCIA Sound Card you can do that. Just google PCMCIA Sound Card and you'll find a ton that are available.
I might suggest a new laptop.

Thanks Mark

How to install PNY OPTIMA 2GB DDR2 667 MHz memory card in lap top


Turn the computer off.
Remove the battery.
Unplug the AC adapter.
Turn the computer bottom-up.
Look for a few screws that secure a small panel.
Unscrew those screws, and remove the panel.
If you've selected the right panel, you should see your current RAM.
On the LEFT and RIGHT edges, there are small "fingers" that are holding the RAM.
Gently pull those fingers away from the RAM, and it should pop-up slightly, and you should be able to remove the RAM.
Notice that the "notch" in the middle of the RAM is slightly off-centre.
Insert the new RAM into the socket, and gently press down, until those two fingers "click" to grab the new RAM.

Depending on your "old" RAM, you may have:
* one "occupied" RAM slot (1GB), and one "empty" RAM slot;
* two "occupied" RAM slots (512MB/stick).

So, you may have to remove one RAM stick, to expose an "empty" RAM-slot "hidden" under the RAM.
Or, the "empty" RAM-slot may be visible without removing the RAM.

Or, you may have to remove one of the 512MB RAM-sticks, in order to free-up a slot for the "new" RAM.

Replace the cover-panel, and screw it in.
Reconnect the battery.
Reconnect the power-supply.

Start the computer.
Click Start
Point at My Computer
Right-mouse click on My Computer
Choose Properties
It should display your CPU-speed and the "new" amount of installed RAM.

Video memory


1) On board video devices often use main system RAM,
by remapping it into their own address space.

This is designed to be CHEAP not GOOD.

Any RAM used by the video controller is NOT available to
to Windows, thus reducing system performance.

2) Sacrificing system RAM for video is a bad idea, the
system needs it more. Extra RAM in video controllers
is used mostly for 3-D effects and gaming, because
most video systems already have plenty of RAM for
implementing colors screen resolution.

On board video controllers are never fast or exotic enough
to benefit from the extra RAM anyway.

The rest of the system (i.e. Windows) on the other hand
can put any extra RAM to a far better use, by reducing
the need to store transient data on disk.

Don't forget that a hard disk is 10,000,000 times slower than
physical RAM, and when Windows starts running out of
physical RAM, it starts swapping data to disk (thrashing).

The performance penalty is not subtle !!!! Operations that
took a few seconds can take hours and even days.

3) It may be possible to change the balance between
system RAM and VIDEO RAM in the BIOS.
This depends on the motherboard.

4) If you want to drastically improve performance, do
buy a separate video card, for example an ATI Radeon
Saphire and disable the onboard video.

You must make sure the video card will fit in your
motherboard. Depending on the boards age, it
can use one of several types of I/O slots:

Vesa
PCI
AGP 2x
AGP 4x/ 8x
PCI Express

etc...

The card must match the slot.

5) The suggestion that adding a separate video card would
somehow slow down your computer is absolute non-sense.

Tell the guy to read some books, take a few classes, and
keep his opinions to himself until he knows something.

Internal video cards (on-board) have limited capabilities,
and steal system resources. Add-on cards are designed
for performance, by adding resources and off-loading
graphics related computation from the main CPU,
allowing it to do 0ther things.

6) Finally, using the hard-drive to supplement video RAM
is impossible. The hard disk is way too slow. It would be
like hitching a snail in front of your Porche. Perhaps
even a little worse.

Video RAM needs to be extremely fast, even faster than
system RAM. It is often organized using ultra-wide buses
with interleaved addressing for maximum speed. Also,
for this reason, good video RAM is not cheap. A good
Video CARD will have between 256 to 512 MB of fast RAM.

If you run Windows XP, your system should have at between
1024 to 2048 MBytes of system physical RAM.

Less RAM will make your system drastically slower when
doing things like video and image processing.

For VISTA, two gigs is the absolute minimum.


Disk are used for storing lots of data at a slow speed,
and retaining it with the power OFF.

Hard disks can store about 1,000 times as much as
physical RAM, but the access time is up to 10 million
times slower:

RAM can be accessed in 1 nanosecond.
DISK takes 10 milliseconds.

Hope this answers your question

Cannot see 4 gb ram


Hi Ciccio8670,

If you are running 32-bit Windows, you must live with it. You will not ever see all 4GB of RAM you've paid for.
If you are running 64-bit Windows, you may have to live with it. Depending on your motherboard's chipset, your system may support memory remapping. If so, you will be able to use all 4GB of RAM.

Detailed:
Due to an architectural decision made long ago, if you have 4GB of physical RAM installed, Windows is only able to report a portion of the physical 4GB of RAM (ranges from ~2.75GB to 3.5GB depending on the devices installed, motherboard's chipset & BIOS). This behavior is due to "memory mapped IO reservations". Those reservations overlay the physical address space and mask out those physical addresses so that they cannot be used for working memory. This is independent of the OS running on the machine. Significant chunks of address space below 4GB (the highest address accessible via 32-bit) get reserved for use by system hardware: • BIOS – including ACPI and legacy video support • PCI bus including bridges etc. • PCI Express support will reserve at least 256MB, up to 768MB depending on graphics card installed memory
What this means is a typical system may see between ~256MB and 1GB of address space below 4GB reserved for hardware use that the OS cannot access. Intel chipset specs are pretty good at explaining what address ranges gets reserved by default and in some cases call out that 1.5GB is always reserved and thus inaccessible to Windows.
