I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

The Thinkpad sticker with the red light above the 'i' doesn't turn on unless the screen turns to tablet mode. Is there any way for the light to stay on all the times? The one near the keyboard does work, the issue is with the light on the outside lid.

Hi all, rather new to the forums here , I have a few of the L470 to set up and to go with the hybrid docks for end users, I am aware that the 470 does not come with USB-C so these new docks wont charge the devices with the USB-A adapters, what I have also noticed which might be a problem to (some of) my end users is that the laptops will not turn on with the dock's power button, you have to open the laptop (and keep it open) and power it on through the device, the peripherals, display etc works fine after. With all the drivers, firmwares and testing on other L470s, Docks, and devices with USB-C (whic i know charges and turns on machines with USB-C ports), am I to assume that with no charge through the USB-A adapter, the function to turn on the laptop through the dock is not there? Thanks,Craig.

Hello forum people,

I have the following problem on my Toshiba Satellite R850 running Win7 64bit: I decided to change the wireless adapter so I can connect to the 5GHz wifi network my router provides which wasnt possible on the Atheros wireless adapter it came with. I changed it to a Intel Wireless AC 3160- the physical change went quick and without problems and while the adapter is basically working now the problem I'm facing now is that the F8-hotkey function to de-/activate the Wifi and Bluetooth is no longer working. When I press the hotkey button all the different hotkey combinations show up on the upper part of the screen, but now there's only F1-F7 and F9, F8 just went missing. Does anyone have any idea how to get it back?

Thanks in advance and take care

Repeated attempts to restart failed and after many attempts, I managed to get to the Startup Repair mode - after a long time, startup repair says it failed to automatically repair the problem

I managed to run system restore but after a while I got the following message: "System restore failed due to an unspecified error. The disk strucgture is corrupted and unreadable (0X80070571)

My laptop did not come with a Windows Vista CD/Recovery disk

My first priority is to recover a few files in the laptop - if I am able to do this, then I dont mind junking the laptop

Since this is an old laptop, I would prefer not to use an expensive professional to recover the data

A week ago, my 11 month old Thinkpad E5500 had a few blue screen episodes. Then, it stopped turning on altogether. When i press the power button, the red 'thinkpad' light flashes, the green Fn key light flashes and a soft but irritating clicking noise eminates from the laptop. The only way to stop these 3 repetitious events is to completely disconnect all sources of power. I have tried everything I can find online to fix this, including pressing the power button, holding it down etc. Disconnecting and reconnecting battery in various combinations.Anyone know what's wrong with this crap laptop?

Okay, a School-issued ThinkPad Edge. It was bought new with a Windows 7 and an intel core i3 processor. I download Skype, and part of the set-up process is the mic part, and that's how I found out that the BUILT IN mic DID NOT work. I've looked around,
but all of the solutions I see I've either already tried, or wouldn't work in this situation (For example, the computer's original OS is Win7, it's not going to be an outdated sound card!) Does anybody have a specific solution? I've tried going in and messing
with the sound levels and the boost, I've made sure the mic wasn't muted. I even have the little green check in that one part saying that it should be working! I have no idea what else to do, and this is a serious issue for a lot of people. I can survive without
the mic for a while, but not forever. I would also appreciate it if I didn't get a hundred people saying that they're having the same issue. If you have a suggestion on how to fix it, then great! Maybe complain a little about your issues with the mic as you're
doing so, but if you're not giving a possible solution, then
please don't say anything here. Hope I get an answer soon! <:)

Hello, I've got a brandnew ThinkPad X380 Yoga and after 3 days of using the pen isn't recognized anymore. I tried to update the driver and first that worked out, the pen was functioning perfectly again and as I checked it's battery it was fully loaded, so it can't be an issue of the pen I guess. But after 15 minutes of using it stopped working again and I couldn't find another solution than resetting and reinstalling the pen's driver so far, which is obviously pretty annoying if you need to do it every 15 minutes. I would be very glad if somebody could help me!

 Received L470 two days ago and immediately noticed a few issues with the display. 1. Screen (full HD IPS, anti-glare) has got a yellowish tint, like the example in this post: https://forums.lenovo.com/t5/ThinkPad-11e-Windows-13-E-and/Thinkpad-E570-has-warm-yellowish-tint-dis...I managed to somewhat correct the yellowish tint by using RedshiftGUI and setting color temperature to 7000K. It's still more yellowish than my other laptops when put side by side, but tolerable for now. I'd love to try out other solutions to this problem.  2. This one is my major complaint. When watching movies, or certain videos with dark setting, screen appears to be too dark for some details to be visible, even at max brightness.  To give you an idea, here is a photo I took using my handphone. (link to photo https://www.dropbox.com/sc/3fsqdu5ztoncwze/AABpthqcCgi7-sY9K_yUZ8ffa )I'll say I can see more details from my handphone than from the laptop screen itself.I've tried playing around in intel graphics setting but nothing seems to work.

What happens when I try to use it is a circle with an up and down arrow appears and I am only able to scroll if I move the mouse cursor beyond the circle, either up or down.

Good morning! Ok here's the deal. I've purchased a used thinkpad a few month ago. The laptop itself works fine, there is no problem with the functionality of it. However since then, I've already had a head crash on the hard drive. It was a Hitachi hard drive and you guys know about them and their crappy reputation with notepad HDs. I've since replaced it with a IBM travelstar, and I think that should solve that problem. SInce that problem, I've noticed a weird problem with the battery. I plug it in and charge the battery fully, then I use the laptop for about 15 to 20 minutes, then it prompts me that I should save any unsaved data and charge the battery or plug into the wall immediately. SO it goes from 100% down to 3% very quickly. The weird part is that it does not descend. I mean it just jumps from 100% down to practically nothing in the snap of a finger. I would have guessed that it would go down to 90% then 70% then 50% etc.... Being a relatively new Laptop owner, I'm not familiar with the way a battery craps out. I would have thought it would be a gradual deterioration, not a sudden meltdown. I must add that I leave the laptop in the docking station when not in use, in a constant charging state. Is this wrong? Am I supposed to unplug it from the wall as soon as it's fully charged? Also, I use a power inverter occasionally and use it in my truck. Would this have any effect on it? Basically, I am trying to get a good feel for the Do'... Read more

A:IBM Thinkpad 600x batteries.

I got my answer.

Well after some homework on the subject on forums like this one, I've discovered what may have happened here. It seems as I overcharged my battery by leaving it plugged to the wall when using it at home. It seems the concensus is to either run the battery all the way down before pluggin in and charging or removing the battery when using it at home. If the battery needs to be in place then I can probably use my old battery now that it's thrashed, and replace it with my new battery whever I get one, to use away from home. Some lessons can be pretty expensive!:blackeye:

On my Thinkpad X1 Yoga with OLED screen, my Miracast never worked.  Lenovo told me it was a hardware problem and to contact Microsoft.  After many hours of effort, I re-installed WIndows 10 Anniverary Edition from Microsoft, but not using the Lenovo image applied when you reset the computer.  With the Microsoft only Windows 10, my Miracast work properly, and while Microsoft installs many of the drivers needed for the X1 Yoga, I did not have the Lenovo Settings program.  I discovered that when I try to install the Settings program, it requires the instalation of the Thinkpad Settings Dependency driver, which I diagnosed causes my Miracast to crash.  Has anybody else had this problem?  If it is only me then it would seem that my X1 Yoga does have some kind of hardware issue, despite their denials.  If others are having this problem, Lenovo needs to repair the Thinkpad Settings Dependency so that I can use the Lenovo Settings program to set the other Thinkpad features to my preferences.  I have managed to find non-Lenovo workarounds to some settings problems but I want the computer to work as promised.

A:My wifi doesn't work

It is a Linux issue, you need to go to a forum that deals with the Distro you are using. Broadcom chips have a big issue with the Linux Kernel no cooperating with them, so you have to use "Man in the Middle" software to get them to work. You are better off using either a Realtek or Intel chip Networking adapter.
