Make sure all the batteries are good

G7 what (G7-1150us)??? 7 years old?
only 3 ways, to corrupt a file
1: PC is virus infected.
2: Hard disk is bad, if S.M.A.R.T disk test fails, it is bad.
3: you somehow, turned off power with the word fail open and this wrecked the fail (xyz.docx)
make sure the Laptops battery is good, try new one? be wise !
make sure to keep the line cord plugged in at all times.
so if you lose power to the home, the battery saves the day
if the battery is bad (old ones are & never seen a 7 year old battery good in my whole life time (50 years on the job)
sorry. for your file loss.
when editing files save it to a new name each time.
like this
myBIO1.docx. myBIO2.docx,
then when the last one is corrupted, the previous is ok
that is if not #1 or for sure #2 caused.

With the line cored (HP 19vdc power pack plugged in)
run crystaldiskinfo...... now.
down load it and run it
and post your results.

this simple program scans the HDD, for errors
Hard drives actually know when they are bad.
(weak HDD are drives with unrecoverable sectors or clusters)
the UN word is the key, there,

This problem is caused by the 'step' inside the battery cover which prohibits the tip of the battery from contacting the nipple inside the cover. I fitted a thin piece of aluminium strip (20thou) and the rangefinder now works perfectly. Most brands of CR2 battery now have higher sides which shield the tip - bad design.

I found that mine works great if I do not over tighten the cap on the battery. back it off little by little until it does work.

Redfield was purchased by Leupold in 2008, and is only able to repair and service Redfield scopes made in 2010 or later. If it was made before 2010, then it isn't covered by warranty, but Leupold does suggest contacting Iron Sight, Inc, if you want to ask about repairs and associated costs. Here's what the Redfield/Leupold website says:

When Leupold & Stevens, Inc.® purchased Redfield in April 2008, it did not acquire the capability to repair Redfield products manufactured prior to this purchase. The repair tooling and parts were purchased years ago by other repair services. Leupold & Stevens, Inc. will service its manufactured Redfield product (manufactured from 2010 forward) in accordance with its published warranty.
At this time, should a non-Leupold & Stevens, Inc. Redfield product require service, we suggest contacting Iron Sight, Inc. (918) 445-2001. This contact is provided for information purposes only, as Iron Sight Inc. is not affiliated with Leupold & Stevens Inc. They should be contacted directly for all information regarding repair, service and associated charges.

The only reason a variable power Leupold scope should lose focus when changing power is that the object you are viewing is too close to view on a high magnification. Try again while viewing something 50 yards/meters away, and if it still loses focus, then it probably needs repair.

Leupold scopes aren't user-servicable, and you wouldn't want to try to take it apart yourself, but that's okay, because Leupold has one of the best reputations among optics manufacturers for standing behind their products. If there's a problem, you can call their customer service department at 1-800-538-7653, or submit a request on their online form here:

Either way, don't give up on it. Leupolds hold their value, and you could probably even sell a problem scope to someone who is willing to send it in for repair.

Good luck!

This is not uncommon with Leupold scopes. The first thing to try is to get a good grip on the adjustment ring and just crank away, making sure you're not trying to go past the adjustment range marks on the adj. ring. If the ring has not been moved recently(like within the past few months) it can take a surprisingly large amount of arm-strong to break the ring loose. The reason the ring can be so difficult to move is because Leupold uses a close(tight) fit to keep moisture out and the dry inert gas(argon or nitrogen) in. I haven't felt a Leupold yet that didn't require substantial effort to move either the power or occular ring. Be sure to wipe down the exterior of the ring to remove any oil or dirt to insure you obtain maximum adhesion between your hands(you did wash them, didn't you?) and the ring. 70% isopropyl/rubbing alcohol and a paper towel(don't soak it) makes quick work of cleaning the adjustment ring. In any event, DO NOT APPLY ANY OIL/LUBRICANT IN AN ATTEMPT TO TRY TO MAKE THE RING MOVE EASIER! All that will do is probably cause the o-ring seals to begin deteriorating, and then you WILL have to send the scope in for repair. Once you have the ring moving, just work it back and forth until it it moves about as easily as it's going to get. If this doesn't work, get on the horn(telephone,email,etc) to Leupold and they'll likely instruct you try what I told you before sending the scope to them. They normally don't consider this stiffness to be a problem as they consider this to be a sign that the seals are working the way they should. Last time I talked to them nonwarranty problems cost $10, warranty stuff was free of charge. Leupold is a class act; they back their product to the hilt. Good luck!

the scope needs to be fixed by leupold or replaced.
