I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hello everyone, my touch screen on my lenovo ideapad z400 touch is not working anymore.  The only weird thing I remember is some ghost touchpoint on my screen. I've been looking for the answer to this issue, but it seems that Lenovo does not address this problem.  If someone has found the solution to this problem and wants to share it with me, I will be forever grateful.

Hi, I have a Z400 Touch laptop Ideapad - Type 6881. I downloaded Windows 10 a little while ago and put all my stuff on a USB drive before changing. After I did that, I had to reset my entire computer because my husband put a virus on it. I changed it back to factory settings and then updated it to Windows 10 again. When trying to put my stuff from my USB back onto my computer, the USB says that it is unallocated. Is there anyway I can get those files back or are they lost forever? If you could please let me know because I don't want to lose everything I have on it.

A:How to reset BIOS Lenovo Z400 Ideapad Touch

Welcome to the Lenovo Community !
 
There is no master password, back door or CMOS clearing procedure that will remove your forgotten password.  This is due to the ease in which laptops are stolen.   To resolve the issue you have basically two options.  The first is for the Uncle to try and remember the password he used.  Please keep in mind that passwords are case sensitive and he may have use upper and lower case characters.  The second option is to replace the motherboard.

Hi lleclair46,
 
Thanks for posting and welcome to the forum!
 
When you inset the USB drive and go to 'Computer', is it showing less space than what there is actually on the drive? You can recover the unallocated space, but this may wipe whatever was on the USB drive.

Hi All,I have a Z400 touch. The keys "8", "I", "K", and "< ," are not working, even in safe mode. I strongly suspect it is due to dust, and I should clean under the keys. My question is; is it okay to pry those keys off the board directly with a screwdriver? Or would it get damaged? EDIT: I bought this machine in 2014, used it as my primary computer until around March 2017, after which I've been using a different laptop.

Recently I updated windows 10 from windows 8.1. I could adjust the screen brightness when I was running on windows 8.1, but I can't do it any more since I installed a driver update from Intel. So I searched solution and managed to reinstall the older driver again and it worked. However when I tried to run a game the FPS became ridiculously low, much lower than it was on windows 8.1.  I found that the other graphic card, Nvidia Geforce GT635m, which had its latest driver installed,  wasn't working properly, by disabling this graphic card in device manager and I got the same FPS. I tried to install the new version of the driver of Intel HD graphic 4000, the GT635m worked again and the game got back to normal FPS while the screen brightness adjustment didn't work. So, here's my question: how could I keep both screen brightness adjustment and GT635m working properly?

Hello Lenovo Community!I own an Ideappad Z400 Touch and I had issues with trying to charge it. Obviously I turned to the forums here and I found a possible solution here. When I tried to perform a battery firmware update, it went smoothly and then suddenly turned off and had a fast flashing orange light. Obviously I knew my battery and/or charger let me down in the middle of the process. I'm kind of scared because I don't know what to do nor have the money to afford a new laptop. What most likely happened to the battery is that it got "electronically disconnected" and technically only relies on the AC adapter which now I have found out is pretty screwed up and stops charging once Windows actually boots up. Is there any way to fix this? Please help! Thank you and have a wonderful evening!

Hello guys,So I have a Lenovo IdeaPad Z400 touch that recently fell from a table and the laptop itself looks physically OK and has no dents or cracks at all, even the glass touchscreen is ok but the top part of the LCD inside appears to be cracked as there are lines and black cracks on my screen. I recently took the laptop to a Lenovo service center and they told me that they had to change both the LCD and the touch screen module (or digitizer as i have heard) as they come in a package, this costs around $300 and is not worth it since my laptop would cost around the same if sold secondhand. My question is whether there is a way to change just the LCD without changing the touch screen module as it works perfectly fine. After taking my laptop to a technician outside of Lenovo, he claims that seperating the touchscreen module from the LCD would almost always result in the touch screen cracking so it would be unusable, is this true or is it possible to keep the old touch screen module and change just the LCD? Thanks in advance

Hello, Lenovo Community, I recently tried updating my battery's firmware. It was going smoothly for about one minute until my charger disconnected and my laptop's battery died and will not charge. My charger has a long history of automatically disconnecting (two blinking lights, one white and one orange) so I cannot power my laptop through the charger itself. I really don't want to get the port checked, so I am looking to see if there are any other ideas from the community.  Here is what's happening:-My charger disconnects everytime I try to boot now (used to disconnect before loading Windows 10)-My battery is disconnected from the system (electronically, not physically probably)-I really cannot power on the system.  Thank you, Lenovo Community!

The error message continues: Nivida windows kernel mode..driver 275.89.That appears to be an HP workstation and the driver dates from November 2011 (assuming Win 7 Pro 32-bit). See here for other OS and drivers: HP Z400 operating systems and driversIt could be an indication that the drivers are corrupt in which case you would need to uninstall/reinstall the graphics drivers again. You can download them from the same site after selecting your OS. But I had a similar message on a Sony Vaio notebook not so long ago and without doing anything, the system recovered of its own accord. I'd suggest monitoring the situation for the time being at least.

Maybe somebody here knows what to do:After I changed the setting of the PCIe-slots to "compute", the z400 no longer starts at all and won't give me a chance to change this setting back to the way it was. I understand that the "compute" setting is reserved for special video cards like the Nvidia Tesla card and I also know by now that it is completely wrong for my needs.When I now press the power button, I see the red light flasing along with the 6 beeps indicating a graphics error. I already tried to reset the cmos by taking the battery out, pushing the cmos button...but no luck.The way I see it, the z400 no longer expects a regular graphics card in the PCIe slots and therefore signals that no card is installed (same error code without any graphics card installed).So: does anyone know how I can change this back to normal? There must be a way!I can't tell you how much I appreciate your help because I'm in the middle of a production and this workstation plays a crucial role.

A:Z400 heatsink fan 4 pin to 5 pin

It is not as easy as you'd think.  HP carefully balances cooling needs with the heat capacity of the heatsink and the fan combination, and applies a certain amount of PWM throttle to the fan so it runs at a certain speed at baseline.  The amount of PWM throttle is specific, and less PWM restriction will be supplied as you boost fan baseline speed in BIOS, and also as the motherboard's cooling control infrastructure responds to specific environmental stresses (such as rising ambient air temperature).  So, even though I can dink with these to my heart's content, I leave them at the HP standards.  Here's the key info if you wish to dink: The Z400s largely use the higher capacity "performance" heatsink and fan with the 92x92x25mm fan.  This is because most of the processors of value for the Z400 are 130W max TDP.  In contrast, the dual processor Z600s processors of value usually run at 95 watt max TDP.  Hence, they usually get the smaller "mainstream" fan.  The more expensive processors run fast at lower temps.... the Z400 usual processors are more brute force (higher voltage solution, hence they run hotter for same fast speed).  The heat of two processors inside the Z600 is something HP needed to master.  To cool the single hot processor in a Z400 probably was easier, and the hot processor got HP more bang for the buck. The Z400 performance heatsink/fan is HP part 463981-001, and its fan is a Delta AFB0912HH, with ...

All drives are in SATA-mode.I also  enabled the ability to boot from removable media in the "storage options"-section.Now when i start the PC, it ignores these settings and starts only from the harddrive.
