You can attempt to reset Bios By Pulling the CMOS battery, you will need to disassemble laptop, Not sure offhand if you have a plug in battery or one thats soldered on... Basically in a laptop there are 3 main types of Cmos battery connections.. 1 is plugged in to the motherboard using a 2 wire plug... 2 is a battery tray on the motherboard that the battery snaps into and out of... 3 is a battery that is soldered to the motherboard from both the positive and negative sides....

With any 3 of these.. You need to remove the battery... HOLD the power button (make sure your laptop battery is removed as well and unplug the AC Adapter... )
Then Reattach CMOS Battery and reassemble and attempt to power on

Note: The Soldered On Batteries Can Be Desoldered and removed...

Do Not Remove the solder from the contact points!! You need to use a pointed flat tool and your soldering gun... Use your tool to pry the battery away from its connection pad... To Do This, First Heat the soldering gun, carefully heat the 2 contact pads of the CMOS battery, as your heating them get the solder to melting point and then quickly pry the battery off the board, heat the 2 connection pads again and pull the battery away from the motherboard.... You should have the 2 contact pads still with solder left on them...

How can I change boot sequence in Compaq Evo N410c?


You need to access your BIOS configuration. 1. To do this, shutdown your computer and boot it by pressing the power button. 2. You need to hit F10 when the computer first powers up in order to get into BIOS (Note that the key is usually different for different computers. If F10 doesnt work, try F2, F12, Delete or F9. 3. Once in the BIOS, you should find the boot sequence option.
Hope this helps!

And follow the instructions here to upgrade the BIOS. I suggest using their instructions as they will be far more accurate than mine for this specific system and BIOS update.

Bios ROM checksum error (Compaq SR5237CL with M2N68-LA MB)


A BIOS checksum error can be caused by a nearly flat BIOS battery.
I would replace the BIOS battery first before attempting to upgrading the BIOS.
Some motherboard BIOS firmware is upgraded by running a program that has been copy to a DOS boot disk or the upgrage maybe done from within the BIOS setup. These firmware upgrage and instructions are on the motherboard WEB site, in your case the Compaq/HP WEB site. Make sure you select the upgrade for your model motherboard.
NOTE it is possible that if you make a mistake you could ruin your motherboard, if you are not sure seek help from a computer savy friend.

Blue Screen of death


According to this link, the memory of Compaq Evo N610c can be upgradable to 1024 mb.

http://h18000.www1.hp.com/products/quickspecs/11382_div/11382_div.HTML

Memory Upgrade for Compaq Evo N610C, the Compaq Evo N610C takes the PC2100 DDR SDRAM SODIMMs Memory Type, and comes installed with of Memory. You can upgrade your Compaq Evo N610C to up to a maximum of 1.0 GB Memory, the system has 2 sockets to install Memory, already with standard Memory installed. For best system performance use the maximum amount of allowed Memory per slot for your system. (Souce: http://www.memorystock.com/memory/CompaqEvoN610C.html)

So you have to install 512mb memory module on each slot to make up 1024mb of memory.

Did you install 512mb memory module on each slot or did you just install 1GB memory module in one slot?

Try to go back to 256mb RAM and see if you will have the same blue screen error. If you did not receive any blue screen, try to add memory into it or just insert 512mb first and then oserve again if you will have the blue screen error.

You may also want to go to these links for other suggestions.

Upgrade 238622-001, Compaq Evo T30 Thin Client 300Mhz 32MB Flash/64MB/Win CE NET/IE 5.5 w/o


You need to replace the 2mbit bios chip used by the WinCE Evo with the 4mbit one used by the NTe and XPe Evo, then you need an add on flash module, since the onboard flash is too small. After that, just find the OS file and flash away. You can find the OS files and a utility to flash from the HP support site. You'll need a crossover ethernet cable, not a patch cable, to do the flash.
