The crazy cursor update
I finally took the touch screen HP laptop (W-10) to the shop in town. No one
had a answer to the problem online. They did a System Recovery which they said would remove all crapware. They reinstalled the latest in W-10 and updated all drivers. They did not charge me anything because the System Recovery made the LT worse. At least the keyboard worked before. The onscreen KY works but the mouse has to be used to tell it where to put the chosen letters. The mouse only works on and off, mostly off. In Googling today and trying to follow what I'm reading - there is no Keyboard listed in device manager for that LT. It's as if it never existed. What happened that it was not installed during the Recovery? The keyboard and touch pad are dead, the touch screen is dead, the cursor is now stuck to the Start button a good part of the time. They suspect it's the mother-board. Any ideas. I don't know where to go from here. Take it to another repair shop? Try and buy a MB and install it ourselves. I'd hate to have to recycle it because it's only 13 months old and my favorite LT. |

You don't have to install it, run it from a USB Stick. |

I'd hate to have to recycle it because it's only 13 months old and my favorite LT. I usually recommend to people that they make a backup image of the hard drive, before giving a computer to a shop for repair. There have been a few cases, where some trivial problem, they erase C: and all the user data files, and reinstall the OS. ******* You could use the BIOS setup screen as a test case. UEFI interfaces for BIOS setup, have a GUI. They accept cursor up and down keys. You can use the Mouse. Maybe the Touchpad also works in there. This is an example of an "OS" before the real OS runs. If you can't do anything, can't get into the BIOS, then it probably is a hardware problem. It doesn't have to be "motherboard", which is a way of saying "we don't know what it is". I remember one shop owner, kept "blaming the MOSFETs" for every problem under the sun. Some of these mom and pop shops, have strange fixations with stuff. The HIDs have hardware, which is generating signals. It could be, for example, a problem with the touchscreen sensor array and the chip in the touchscreen that converts inputs into USB packets. The motherboard components might be perfectly happy. And just the touchscreen is generating a blizzard of events and the driver doesn't know what to do with them. It sounds like it's some hardware component, but you'd need a way to disable them one at a time, and that can be hard to do and remain in control of the machine. That's a kind of "fault isolation", where you eliminate items as being contenders, as you go through the hardware list. ******* With a linux LiveDvD or USB stick, you could use (in Terminal) sudo lsusb sudo lspci and see if the basic hardware items are reporting in. When it comes to Human Interface Devices, they have all sorts of crazy ways of connecting them. While you would expect USB to be used, they could be serial or PS/2, and in some cases, the hardware lacks PNP (plug and play) information. This also makes it difficult to (safely) make drivers for the things, because without PNP, the driver doesn't know if this is the right computer to be using the driver or not. Let's just hope this machine doesn't have a "hodge-podge" of bus connections for this stuff. Paul |

Trying to install a motherboard into a laptop yourself, especially if you've never done it before, is not a good idea. |

Unless you experienced something that would physically damage the motherboard, such as a large voltage surge, this sounds like a driver problem to me. Unfortunately, it may not be an easy one to solve, but I would start by thoroughly studying the System Error Log. That should give you some idea what is failing. -- best regards, Neil |

It's been off for hours and I turned it on a it's working OK. That is except for the touch screen. That's not working. The touch pad is. But it doesn't last. Soom the cursor goes wacky and the second cursor appears as a capitol I while the normal one sticks to the ON botton. Suddenly the keyboard is working again again - I have i t right next to me here.

They all seem to be now. When I shut it off earlier no Keyboard showed in device manager. It shows now. It says it's stadard PS/2 keyboard. The mouse is a HID-compliant mouse. Touchpad is SMBus.

Why does it more or less work when first turned on after a rest period, then goes nuts? |

What is the relevent info there? I see no "error log" anywhere there. The search feature a the botton left next to the start button doesn't search the computer, just the net. Does error log have another name under W-10? -- best regards, Neil |

I was wondering about the power supply. Battery seems fine. It runs a long time on a charge. |

If a clean install didn't work in Windows and the issue appears in Linux, chances are that hardware is indeed at fault. You said that this was a Dell machine? |
