The WiFi connection of the DELL D610 Latitude sporadically disconnects itself. When the D610 is operating in battery mode, occasionally the WiFi indicator next to the Power button goes off.

Just 2 days after the cable repair of the DELL AC Power Adapter for a DELL Latitude D610, the same problem appears again. During startup the BIOS reports "The AC power adapter type cannot be determined". Murphy's law at it's best!

2009 has started well, but not for the screen of the D610. After coming back from Windows standby the screen was black, although the harddisk made all the familiar noise of startup. At first it seemed key code Fn+F8 (CRT/LCD) was pressed - this redirects graphics output to the external monitor VGA connector. But that wasn't the case.
 

Your system will operate slower

After many flying hours with the DELL Latitude D610, suddenly the DELL AC Power adapter stops charging the laptop battery. At startup the laptop beeps and reports the following BIOS message

"Power Adapter not recognized".

"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation."

GREAT!!! The 120 Gb - 2,5" inch Samsung hard disk - HM121HC - has crashed big time. With it's production date of October 2007 it lasted for about 8 months in the Dell Latitude D610. Somewhere in the boot / partition records the disk surface has gone sour.

Blue Screen of Death - BSOD

Since 1 week the Dell D610 Latitude is plagued by sporadic blue screens (BSOD) with various STOP messages, sudden reboots or a frozen screen. The frequency is a few times per week or sometimes 2-3 times per day. It seems there is no relation at all with the activity performed on the D610 laptop. Also this has never been seen before on this laptop. Nothing was changed when the problem started to occur.
 

Two identical DELL refurbished DELL D610 laptops join the journey! Bought in Islamabad in a laptop shop. After serious testing with the DELL Diagnostic software the laptops are purchased with 2 extra batteries. The totally "worn to the threads" Inspiron 4100 and the backup goes into retirement.

Screen intensity is starting to fade gradually - during the day the screen becomes hard to read at maximum intensity / contrast. Only in the evening/night the screen emits enough light to be readable.

While connected through LAN to a router the network connection of the Inspiron 4100 suddenly goes down. The system tray notifies that the LAN cable is disconnected. At first a bad LAN cable is suspected. Using 2 other LAN cables doesn't resolve the problem. Rebooting doesn't either - the LAN card doesn't respond anymore.

Sporadically while starting the Inspiron 4100 results in a Windows Xp Pro lock-up. Although the processor is still alive (numlock light still goes on/off when pressed) It runs XP Pro Sp2 with all patches. It seems it hangs on TCP/IP communications - the lights at the back of the UTP outlet stop during startup.
When this occurs it keeps on occuring. Only a restart into safe-mode, then restart helps to resolve the situation.
