I have an "old" (5years) DELL Latitude D610.
Everything was fine, until it hung in Windows.
When I tried to reboot it, something very strange happend : Most of the time Bios load stops at approx. 1/5th of the full bar.
Other symptoms which happen sometimes :
- Bios load is fast until half of the bar, then it takes ages to load the second hald and then hangs without going to Windows.
- Sometimes, Windows boots, but then it "seems to hangs" after some minutes (actually Windows is really slow to reply to a Ctrl+Alt+Del for instance), or if I hit the power button, the shutdown windows appears after 30-60s but no luck to press Enter then to accept, and mouse is not working then.
But the bios stopping at the 1/5th is the most frequent case.
I tried to do the following :
- remove / replace memory
- remove / replace keyboard (obviously)
- boot with / without Optical Drive (taken out of the laptop)
- boot with / without Battery
- boot with / without docking station
- Clear CMOS (remove the coin-battery , wait minutes, and put it back). The BIOS was well cleared as BIOS asked me to enter back SETUP so set Date and Time. After resetting values, values were kept correctly after reboot.
I have never seen such behavior.
My guess is that the coin-cell battery is dead ... but hard to mesure how much is left inside.
Any ideas please ?
