I have an old EliteBook 2540P laptop, circa 2012 – but it’s a 4-core i7 and, fitted with an SSD, it’s still a fast and capable machine. The small form factor and 1280x800 display suit me well, and it’s easily my favourite laptop I’ve ever owned. The display brightness isn’t the best, but using mains power it’s adequate.  

 

However, the display has gone dim – as if set to 50% brightness, even when  explicitly configured in Win10 to 100%.

 

Googling around, I found this support page https://support.hp.com/th-en/document/c00832191 and started following the steps (though not in order). On two occasions I actually thought I’d fixed it – I got the display to return to full brightness. (1) After doing a hard reset for the first time and (2) After updating the BIOS to the lasts available. In both cases, at the next boot it went back to dim operation.  

 

Frustratingly, the last step described in the support page above [Step 6: Check the display before Windows opens] doesn’t have a solution ……and it’s 100% obvious that the display is working during BIOS setup. It’s only when an OS is booted that the problem occurs. True for Windows booting from the HDD, also Linux Mint booted from a Live DVD.  

 

I’ve run out of things to try – anyone got any further ideas?

 

Thanks

Morning, all

 

I have just received the above laptop, as much as I do love it I can't help but think the screen could be defective.  Whenever I look at the screen it feels as if there's some sort of mist/fingerprint/grease/mildly pixelated mark.  I literally want to grab the microfibre cloth and polish the mark away.  I normally use a desktop with an LCD screen, so I am not too sure whether it's my eyes playing tricks on me, but it does feel like the screen is almost "dirty", which is very noticeable while working on white backgrounds.  I have tried calibrating the screen to my desired preference, however, the display just seems a little off for my liking.  The screen is glossy as opposed to being matt - perhaps this is a common trait?

 

Could someone perhaps shed any light on this?

 

Much appreciated.

Hello, I am have installed a new update of Windows yesterday night, 18/05/2018. After the update, I am unable to change the brightness of my screen. To make the matters worse, the brightness settings are all just disappeared from my PC. I have followed the steps of the HP support assistant, and tried to update my "display adapters" in the device manager. However, the display adapters are vanished too! 

 

I would appreciate if someone can help me as soon as possible.

Некорректно отображаются шрифты в некоторых приложениях и их масштаб. В настройках стоит рекомендуемое масштабирование (125%), сглаживание шрифтов включено, перепробовал уже все варианты. Некоторые частично решают проблему, но приложения становятся маленькими и шрифты не везде четкие. 
На форуме Microsoft говорят обращатся в поддержку производителя ноутбука. 
В чем может быть проблема и как ее решить (драйвера стоят самые последние)?

Hello

 

Well, the touchpad is locked when you press any key, and continues to lock for about a second from the last key press.

Can this be fixed?

 

P.S. Sorry for the "google translate"

Hi,

I'm on a laptop whose owner said to have a working touch screen for several months ago. But it somehow stopped to work.

The HP website tells me the laptop is a 

HP 15-g014dx TouchSmart Notebook PC (ENERGY STAR)

and the warranty has expired.

 

My hope is that there's no hardware issues and hopefully just some kind of driver that is gone.

 

I did try research on download driver page on HP website, but for this model it didnt show anything regarding touch screen.

 

I've checked under device manager, under Human Interface Devices, I cannot find any touch compliant.

Previous day I searched regarding this and found youtube videos of someone having it for a touch screen laptop. Now I wonder if that's what missing and where I would find that for this laptop?

 

Or would simply be adviced to reinstall Windows if we cannot find solution, would that make a possibly fix?

Hello all. I am not very tech friendly so forgive me. I recently purchased a fairly inexpensive HP 15.6 touch screen laptop for me son. My son closed the cover very hard and fast, subsequently damaging the screen. There is no cracks, but the image is bleeding and extremely disorted. I am attaching a photo for beter understanding . I am having difficluty locating a reasonable inexpensive replacement. Can anyoine offer son insight (i.e, price and difficulty installing it myself).

 

I paid 400 for the laptop and UBREAKIFIX wanted to charge me 250 plus tax.....

 

Thank you,no cracks, just bleeding throughout

I have an HP21 all in one PC. The hard disk died and I replaced it. The new disk is unformated. I have a boot CD and a USB bootable flash drive. The HP21 will not recognize either of them. I tried pressing F10 on power up but the firmware does not have a boot drive option. The diag. did pass the hard disk via quick test, but there are no partitions on the drive yet.

 

Any guidance?

I currently own an HP envy x360 and I am wondering if there are any stylus out there that I can buy so that I can use to animate and draw efficiently with this laptop. I don't want to go through the hassle of buying a Wacom tablet and was wondering if there is any stylus I can use to animate/draw, utilizing the touch screen feature of this latop. Also any tips on which softwares to use to animate and draw would be kindly accepted.

Enable the synaptics touchpad while typing.

So I am attempting to play a game on my laptop but am unable to use the touchpad while I am "walking" (typing) on the keyboard. I have been trying to fix the issue and this is what I have tried so far with no fix:

 

-Updating Synaptics Touchpad Driver to newest

-Can't find option specifically for disabling touchpad while using keyboard

-Disabled "SmartSense"

-PalmTracking is no longer a visible option for me in the device settings

-Fully updated all drivers, frameworks, and  Microsoft Visuals

 

This is actually my girlfriends laptop and I could just give her a wireless mouse but she oddly feels more comfortable using the mouse pad lol. Whoever finds a solution to this will have my eternal thanks and blessing because I am at my wits end.

 

PC:  HP Notebook - 15-ay009dx

So about 2 weeks ago i accidentally Tripped over my charger cord and broke it so i borrowed my sisters since she also had a HP Notebook and never used it till recently. i bought one of amazon ( https://www.amazon.com/gp/product/B012NQ4KPY/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 )

the  mouse  and touch pad pointer moves on ts on.  all the time, and YES i have  re set the computer to factory default and the problem remains  AND  Yes i have update  the drivers both the synaptic and the bios  and all the other updates over and over and over again. 

 

the laptop i have is under warrenty and it is a big fat lemon and i strongely urge no one to buy it.    every single day i have to either relod the bios and or the synaptic tocuh pad,  just to get maybe a hour of time in which the pointer is not mis behaving  either fix the problem or give me a new computer
