Question about Symbol PTC 701 Portable Terminal
You only need this eprom if you want to save the programs with during power off for 1000 hour.
It is still possible to download programs to RAM memory shared with the data. It have a backup battery (3volt CR-2025) inside the back shell to keep RAM in some weeks without batteries. But if your programs are big it's better to have them in PROM. It is a standard eprom in a funny litle carrier (made by molex). You need to now if cpu-card have a CMOS label inside. If it is there, you need a CMOS EPROM. In other case you need a NMOS EPROM device. 27128, 27256 or 27512 will do.
Telxons partnumber for this carrier is 08892-000 if you find any and Molex partnumber is 9775-548-28.

To run the check disk utility you will need a repair disc or
a operating system disc. Put the disc in the cd drive and boot from
it. You want to get to the Dos Command Prompt (Black screen with white
letters) and type the following command: chkdsk /r
Check disk will run well over an hour or two and you will notice the percentages going from high to low, this is normal. Let it run to completion. Then reboot machine.
If check disk fails to solve your problem you might have to reinstall windows. Try doing a Repair Install that way you don't loose your data, documents, music, pictures, videos or programs.
In windows xp you get to the dos command prompt by selecting R for repair when the options appear.
In Vista and Windows 7 you want to get to the recovery console and look down at the bottom of the window for the Dos Command.
Check for a bad memory chip or memory slot.
Remove the Power Cord, Remove the Battery, Remove the Cover that houses the memory on the bottom of the laptop then remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.
