Question about Dell Inspiron XPS M140 Notebook

1 Answer


I don't know what happened a week ago. Only way I can bootup the laptop by removing the memory stick. Dell has a built in 256M on the motherboard which allows complete computer ops, but extreme slow. I have replaced the original stick with new ones of 512M 1.0G memory stick, but no help. I have done Dell Diagnostic. All components testing OK. I have checked the software enviornment, but do not detect any conflict. I am getting not much help on Dell site. I would appreciate if anyone can give me some help here.

    boot sequence was already setup by Dell. USB was #3. I even took out USB from the boot sequence, but no help. During start, 3 LED lites light up. Middle one looks like a lock (A) blinks 8 times, then pwr shuts down. 512M & 1.0G memory sticks I bought, the dealers swore that it is compatible with my laptop. Sometimes I keep pressing start button, it will start but stops with a statement something like your *memory has changed, reducing amount of memory* & then nothing happens. Any help?

Normally you boot up the laptop without a memory stick in the USB port.
Check your BIOS settings for the boot up device order.
You should have the hard drive as the first boot device, you can have the CD as the first boot device and the hard drive as the second boot device.
You should not have the USB port as the first boot device.

    You had me confused "the mempry stick" you referred to is not the USB memory stick but the memory modules (ie. RAM), now I understand your problem.

    You have purchased two memory modules, one 512Mb and one 1Gb. am I correct?

    Your laptop has two memory slots and the specs for your model state that it will support 512Mb to 2Gb of RAM. The RAM must be DDR2 with speed of 400Mhz or higher. (If you use slower memory or a mix of slow and fast memory, the computer will run with the slow memory speed).

    When you insert more memory into a computer the BIOS detects there is a change in memory capacity and normally you need to configure the BIOS to reflect the change in total memory size. Then reboot your computer and it will boot up normally.

    If your computer does not boot up normally then you have a memory problem (ie. RAM), and this could be :-

    1. The wrong type of memory module (see the specs.).

    2. The new memory module is incompatible with the existing memory module (your existing 256Mb module won't work with the new modules). To test if the new memory modules will work in you computer, remove the existing 256Mb module and insert the 512Mb or 1Gb memory module in the computer and see if it works.

    If both memory modules work separately in the computer, then insert both the new memory modules in the computer to see if it works. If it does then you are OK with 1.5Gb of RAM in your computer. If it works with the 1Gb memory module that is OK too, it is better that the original 256Mb.

    3. It could be that the RAM needs to be inserted in matching pairs (ie 2X256Mb or 2X512Mb or 2X1Gb) but not mixed memory capacity modules. This usually isn't a problem.

    Try these solutions, it should solve your memory problem.

    Remember next time you have a problem, try to give as much precise info as possible together with error messages etc.

Need to reset the bios password on my dell xps m140 laptop.

You would have to reset the whole bios to default which maybe something you cannot do. The only other method would would be to take the laptop apart and remove the battery that keeps the motherboard BIOS memory powered. It should look like a large watch battery. Remove for 5 to 10 seconds, and replace. Then put the laptop back together and that should reset the BIOS, password and all.

Need drivers to run windows 98se on dell xps m140

Microsoft (and Dell) stopped supporting Windows 98 a few years ago -- it lasted for over TEN years! So, it is *NOT* likely that you will find drivers for any computer that was "designed for Windows 2000" or "designed for Windows XP" or "designed for Vista".

So, in general, it is a _bad_ idea to connect any computer running Windows 98 to the Internet -- Microsoft has issued many "security-fixes" in the 4 years after they stopped supporting Windows 98 and Windows ME.

Dell XPS M140 laptop shuts off after powering on

Most laptops that I have worked on that power off that quickly turned out to be an overheating problem. Is the cooling fan running for the brief period that you can hear the hard drive before it powers off ? If the fan is running another potential resolution might be to remove the processor and apply new thermal paste.
