Most batteries have a indicator lights ion the battery. Look for a small button. When the button is depressed indicator lights should light up. If the battery is dead they will blink or not light up. Hope this helps.
If the indicator lights work you may have to fully discharge the battery and recharge at least twice to bring the battery back to life.
All notebook batteries need to be regularly discharged and recharged or they will fail.

IBM thinkpad R51 won't boot and the blue screen with unmountable-boot-volume comes up and i cannot bypass it.

Sounds like at least a corrupted OS, but most likely a bad hard drive. I'd try reloading Windows (if that's your OS) first, which should take well under an hour; if reloading takes excessively long, then the system is probably having a hard time formatting the hard drive due to physical bad sectors and the easiest thing would be to replace it. The R51 uses good old ATA/IDE 2.5" 9mm height hard drives, which are not available in most stores any longer, but you can probably get the same size or larger ones on eBay for pretty cheap and replace it yourself. Expect to pay about 50 cents to 75 cents per gigabyte - anything more would be considered tourist prices...

I have an R51. Sometimes when it is closed it will go into sleep mode and will not wake up after reopened. Also the Access IBM button does not seem to be working.

it maybe caused the system is too heat or the battery is not charge well (your battery is not good)
if the system is too heat you can buy some thermal paste, put it on your processor
if it cause your battery consider to replace it
