Question about Dell Latitude D510 Notebook

2 Answers

No connectivity via Com Port 1

I am a telephone engineer and I use my laptop to interface with the products I am responsible for at customer sites. Recently I connected to a telephone system to carry out some configuration using Com Port 1 (V24). When I had finished I disconnected as usual. I then had a need to reconnect to the system some 10 minutes later but I could not. I have been unable to connect to anything via Com Port 1 since. All my cables check out ok. I have carried out all the diagnostic cxhecks available on the laptop including the BIOS. They all report that all is ok. Could this be something more basic such as an electrical problem on the interface between the laptops system board and the socket? How can I prove it if it is?

There is a program called PC Doctor that test computer hardware including com and printer ports. I have an earlier version that runs from a boot floppy. Do a Gogle search for this.
I also have Checkit, its an old program and runs like PC Doctor and uses a loop back plug which you attach to the com port to test signals in and out of the com port, don't know if it is still available.

You need some way of sending info, you can do this using a loopback plug and some sort of software.

loopback plug is easy to make, you can use Hyperterminal or some testing software (easier to use testing software)

try this freeware test software (page also has loopback plug diagram)

I cant send a fax or reseave one


Sir/Madam

Solution one: Check the fax connections Use the following steps to check the physical connections, and then use the HP Fax Test Service.

Step one: Check the physical connections

  1. Disconnect the telephone cord from the HP fax product, and then examine the connector on the end of the cord. Make sure that the cord has only two wires. Figure 1: Two-wire telephone cord

fe080726-3749-4408-9bf4-fb54019e59a9.gif
  1. Four-wire telephone cordGraphic: Four-wire telephone cordIf the cord has four wires, replace it with a two-wire phone cord.
    If you must use a cord with four wires, use the converter that shipped with product. The converter allows a cord with four wires to work with a device that requires a cord with two wires.
  2. Connect one end of the telephone cord to the telephone jack, and then connect the other end of the cord to the port labeled 1-Line on the back of the HP fax product.

If other devices need to use the same telephone jack, make sure that they are connected to the 2-Ext port on the back of the HP fax product.

    6 - Two-wire telephone cord to 1-Line
  2. Pick up the telephone receiver and listen for a dial tone. Make sure that you can dial out using the telephone keypad.
    If there is a dial tone and you can dial out using the telephone, the HP fax product is connected correctly to a working telephone cord and telephone jack. If there is no dial tone, check the configuration again and make sure that it is set up correctly.If You Still Having Hp Printer Problem Then Visit Official HP Printer Website On Below Link URL http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c02263145

Where are the ethernet ports


Most desktops only have one ethernet port on their network interface cards. You can find this port on the back of the computer and is used for connecting to a network via an ethernet cable (CAT5/6/7). The port looks very much like a telephone port only larger as it has eight pins inside rather than than two or four for telephone ports.
What is the model number of the computer and we can check whether you should have more than ethernet port or not.

How to connect my laptop via RS232 to my NEC XN120 telephone exchange using the PC Pro telephone system software in order to programme the exchange?


I connect mine with the RS-232 cable in the side of my laptop. It's a Toshiba rinning Windows XP (nee Vista).

Since you're asking the question, I guess you don't have an RS-232 port. For my Vista machines without serial ports, I own a USB to RS-232 adapter cable. On our side of the pond, they carry names like Iogear GC-232. Here's a U.K. search result http://www.amazon.co.uk/USB-RS232-Converter-Cable/dp/B00077DJIQ

Sometimes, you have to go into the device manager and change the port assignment of these adapters to something in the 1-4 serial port range. That was common with the old software.

C5180 all in one is not connecting via ethernet.


Before you begin: Check requirements Make sure you have the following items:
  • One of the following types of wired access points or routers: Ethernet router, switch, hub, or wireless router with Ethernet ports
  • A computer that connects to the wired access point or router
  • A Category 5 Ethernet cable to use for the HP product. (Do not use a standard telephone cable.) Figure 2: Cable comparisonc01710115.gif 1 - Ethernet cable 2 - Telephone cable (do not use) Although an Ethernet cable looks similar to standard telephone cable, each has a different plug and a different number of wires. The plug on an Ethernet cable (also called an RJ-45 connector) is wide, thick, and always has eight wires. The plug on a telephone cable is narrower and has between two and six wires.
Are you changing from USB connection to Ethernet connection?If you previously installed the software for a USB connection and now want to change to an Ethernet connection, follow these instructions to remove the USB installation before continuing.
  1. Click Start , click Printers and Faxes , and then right-click the icon for HP product.
  2. Click Delete to remove the product.
  3. Disconnect the USB cable from the product and the computer.
Step one: Connect the HP All-in-One to the network
  1. Remove any plug or protective cover from the Ethernet port on the back of the product. Figure 3: Remove plugc01710117.gif
  2. Connect the Ethernet cable to the Ethernet port on the product, and then connect the other end of the cable to an available port on the wired access point or router. Figure 4: Connect the Ethernet cablec01710118.gif
  3. Connect the power cord to the product, and then plug it into an electrical outlet.
  4. Turn the product on.
Step two: Decide whether to install with the product CD or download the software Don’t worry if you don’t have the product CD! You can download the most current software available for your product from the HP Web site at no cost. The following information might help you decide which installation method to use:
CD Download For a new product: CD installation is a quick and easy method. If you do not have a CD, you can download the software you need. For an older product: CD installation might not work if you are installing the product on a computer running a newer operating system that released AFTER the HP product released. Downloading the software provides the best results for your older product. Even though it takes more time than using the CD, downloading the latest software can help you avoid installation issues.

Downloading is the recommended method if your computer operating system released after the HP product released. About the software: The software on the CD is current to the date of the product release. The software that you can download from the HP Web site is the most current software available for your product. HP often updates software and drivers AFTER the product and CD release to the market.Step three: Install the software

Checking oil in generator


I found some website help. I have this same problem.

http://www.powermate.com/faq.php?cat_id=3
http://www.powermate.com/faq.php?cat_id=3&faq_id=32

I also found out a lot about the Powermate company via a customer service email reply: This has an elusive customer service number that i have not tried yet.

"
Powermate Corporation is not a part of The Coleman Company, Inc. They have been an independent company for over 10 years and we have no information on their products.

Powermate manufactured generators, pressure washers, air compressors and air powered tools. Information about those products was available from

Powermate Corp.
125 Airport Road
Kearney, NE 68848

Toll Free: 1-800-445-1805 (disconnected)
or 402-758-6303 (disconnected)
Web Page: www.powermate.com

Earlier this year, Powermate transferred the right to sell air compressors and air powered tools to a company by the name of MAT Industries, LLC, 625 Barclay Boulevard, Lincolnshire, IL 60069, 1(800) 628-8815. This company may be able to help you with questions related to air compressors and air powered tools.

In March 2008, Powermate filed for bankruptcy protection. We understand that customer service inquiries to Powermate via emails, mail and telephone calls will not be answered. However, some information about Powermate and its products continues to be available at their website.

If the problem with your unit is with the engine, check the engine manual that came with the unit to determine whether the engine has a separate warranty from the manufacturer. When Coleman was affiliated with Powermate, they did. If so, you can contact the engine manufacturer for a listing of warranty centers in your area. The contact number should be in the engine manual.

If you are needing parts for a powerwasher, please visit the site
