Question: Can I use this to unscrew screws at the back of  the thinkpad laptop, or any general laptop computer? (Can it reach deep enough?)
Document: I'm a certified computer repair technician, I bought this in the hopes to help speed up some of my repairs on laptop that can have up to 20 screws just to remove a palm rest. The problem I have with this is that it is just to slow. Now I know you don't want anything with to high of rpm with small screw like in a laptop do to the fear of stripping them. However this thing is no wear near fast enough to worry about that.
After a few uses with this thing, I just put it away and haven't come across many instances when it's proven to be even slightly more useful than my regular set of "finger-powered" micro screwdrivers all of which have better magnetization and better grip. If you plan to use this for laptop repairs then good luck removing any factory screws that are put in tight and then have fun dropping and losing screws as you try to put them back in with the barely magnetized bits that are provided.
I purchased the #500 a few weeks ago and I use it all the time... Great for electronics/computers. The screwdriver has no problem taking the screws off the back of a computer (a nice tork ratio). I really like the control of the push and hold on/off switch and it fits in my hand very nicely.... I'm using it mainly for electronics but I see many applications...
Don't know what's up with all the rave reviews for this product and why the reviews that are critical of it are getting voted down. This is a completely WEAK and useless product. WEAK magnetized head that barely will hold the smallest of screws (such as laptop case screws). WEAK torque, you will strip the bits if you try to unscrew something that was put in with any decent amount of torque.
Anyway, it lasted long enough to unscrew the 12 or so screws I had to undo. I noticed that the driver clutch was already slipping. When I had to go forward, the driver was only able to limp through 3 screw downs and was no longer working before the 5th screw was set. I did not over torque them. I was careful yet, it failed. Luckily I had a hand driver that worked. I did need the torx bit to finish the project.
I am a Computer tech so this Item was supposed to be an asset for me but it didn't turn out that way,after less than one month of use while removing a Motherboard from a computer Case it stripped rendering it useless,just imagine my disgust. I'll just go back to my old way of doing things ,I surely will not buy another one of these or recommend that anyone buy one.
I would only use this thing for maybe eyeglasses. I began using it to unscrew small Philips screws holding hard drives in server cradles. It broke on the second hard drive. It is small an easy to lug around, but if you use it for any real work it will break.
I purchased this and it worked for 1 day. On the second day, it would not go in reverse anymore. The back of the package stated that "General Tools warrants this screwdriver for one year against any defects.....It will be repaired or replaced at no charge. Simply call our customer service number......etc."
i haven't been able to use these too much. they came with batteries that test as good, but this screwdriver is so weak. it will not unscrew unless the screw is really loose. new batteries made no difference. i had to use my old precision screw drivers to loosen screws first. no use for this.
I frequently open up my computer laptop cases to repair or upgrade them. I'll never open another laptop case without this screwdriver. I'm on the Amazon site today to order another Ultra Tech Power Precision Screwdriver for myself and a few more for friends.
