Product Support Bulletin
Subject: Proper Method for Running Benchmark and Diagnostics Programs
Date: 06/04/93 PSB No: S-0158
Page(s): 1 of 1 Originator: MWT
This bulletin describes the proper method for running any benchmark or diagnostics
programs. This applies to any computer system.
In most cases, the computer should be started using an MS-DOS boot diskette
that’s ‘clean’ -
in other words, one with no CONFIG.SYS or AUTOEXEC.BAT files.
The appropriate executable can then be run, either from diskette or hard drive.
There will be some exceptions to the above rule. In attempting to benchmark or
troubleshoot any add-on that requires a device driver (CD-ROM, local area network,
etc.), obviously the necessary device driver(s) must be loaded. Also, some
programs will require a minimum number of FILES or BUFFERS to be defined in
the CONFIG.SYS file. Such programs will usually display this requirement if they
are run without the necessary CONFIG.SYS file.
For the most consistent results, use the absolute minimal boot configuration that’s
allowed by the hardware being tested.

Subject: Equity LT Battery Life and the AdaptaPAK Battery Pack
Date:

Page: 1 of 2
PSB No.: S - 0096
Originator: BGB (-7 ;i4
The purpose of this bulletin is to provide the test results of the Product R&D’s
AdaptaPAK Battery and usage instructions.
Like the Equity LT’s internal battery,
(refer to PSB S- 0055) there are several usage variables that can have a
significant effect on the working time.
In this test, the Equity LT was configured with the 20MB hard disk drive and the
EL (electroluminescent) backlit LCD and set at 10 Mhz. This is the most popular
configuration and also the one that consumes the most power. The first test was
with heavy access, constantly using the hard disk and floppy disk.
The internal battery was previously discharged. The laptop and AdaptaPAK
battery were charged for 18 hours.
The battery charge lasted a total of 5 hours
and 15 minutes before it ceased operation.
The second test was with minimum access and the hard drive turned off after
powering on. The internal battery was previously discharged. The Equity LT and
the AdaptaPAK battery were charged for 18 hours. After turning on the unit, a
program that didn’t require any keyboard input was executed. The battery charge
lasted a total of 8 hours and 15 minutes before it ceased operation.
NOTE: The battery lives listed in this document are the results of our tests.
Your experience may vary as battery life is affected by configuration and
usage.
We can also assume that if we were to follow the guidelines (PSB S-0055, P3)
to extend the battery charge time, we would get even better results.
AdaptaPAK Battery

SUBJECT: EQUITY LT BATTERY LIFE
The purpose of this bulletin is to provide additional
information regarding battery charge life with the Equity LT.
There are several variables that can have a significant effect
on the working time obtainable from a charge. These include:
Configuration
I/O activity
Battery condition
Processor speed
Environment
Configuration
One of the more popular configurations of the Equity LT is the
hard disk drive model with the EL (electroluminescent) backlit
LCD. Obviously, this is also the configuration that will
consume the most power and provide the shortest working time
on a charge. For example, here are some comparisons between
various configurations:
CONFIGURATION LOW BATTERY TOTAL LIFE
Dual FDD, Reflective LCD (NA) 6:00 Hours 7:00 Hours
Dual FDD, Reflective LCD (FA) 1:20 Hours 1:50 Hours
Dual FDD, Backlit LCD (NA) 5:20 Hours 6:lO Hours
Dual FDD, Backlit LCD (FA) 0:55 Hours 1:20 Hours
HDD, Reflective LCD (NA) 4:00 Hours 4:40 Hours
HDD, Reflective LCD (FA) 0:45 Hours 1:05 Hours
HDD, Backlit LCD (NA) 3:45 Hours 4:20 Hours
HDD, Backlit LCD (FA) 0:25 Hours 0:40 Hours
NA = No access: No activity including no keyboard input
FA =
Full access: "COPY A:*.* B:" or "COPY A:*.* C:"
(These times are a representative sampling. Depending on
configuration and usage, your times may vary.)
It's apparent that drive and backlight usage has a dramatic
effect on working time.
