Hello,

I'm French and I followed your discussion carefully.
I bought two portable probook 4720s which both have the same problem.
Following a fourth call to HP support SAV, they must change my motherboard.
I'll keep you posted to let you know if this has solved the problem.
 

 

Cordially.

Hi,

 

No news for the moment.

SAV told me it could take at least 10 days.

 

I'll let you know upon receipt and testing.

Re: HP ProBook 4720s - Keyboard problem

Interested in this - I took mine back after 48 hours of keyboard problems with MS office (Word) - I had removed all software before attempting to return so they tested with notepad in the shop and could find no problem so did not refund/replace.

Cheers

Re: HP ProBook 4720s - Keyboard problem

Hi, It doesn't depend on software, I think. Most of issues, described here is hardware related. I'm waiting another persons posts about the result of motherboard replacement. I wonder if it helps to solve the problem

Re: HP ProBook 4720s - Keyboard problem


IhorKo,
HP is aware of this matter and does take customer reported issues seriously.  The ongoing analysis to determine the cause remains a high priority.  

This post will be updated when the resolution is available.  If appropriate or necessary, you might consider using an external keyboard until the resolution is available.

ProBook 4720s Keyboard problem

[ Edited ]

Hi there,

 

i've got a ProBook 4720s (17", i3 M350, 2gb ram, 250gb hdd) and i'm issuing this keyboard problem: from time to time (usually when i need to type a lot ;)) it loses keypresses. This not depends on typing speed - i've made some experiments. Warranty dealer reaction is like: bring it to us - we'll replace the keyboard, but people say in forums they replaced and it still appears. I know it's hard to cure this kind of bugs, but hope you can have any additional ideas except BIOS update (already updated) and experimenting with BIOS settings (already experimented with disabling everything, VM suppport and HT support) - the bug returns. Unfortunately there is no regularity or any appear rule noticed.

Re: ProBook 4720s Keyboard problem

nothing yet :(

Didn't you have these problems before you reinstalled Windows? What Windows you had, and what is new one? Could you try to install all hp native drivers from their suppert website and write back if this helps?

 

I'l like to ask - what OS uses everyone who has these issues?

 

I'm using Ubuntu Lucid + Windows XP SP2 via VirtualBox, and i noticed, that problem occurs much faster if VirtualBox+WindowsXP is working. I switched off VM support in BIOS and VBox both, but this not helps.

 

Maybe memory?

A question to HP: is that normal to have this memory by default:

Hynix 2Rx8 PC3-10500S-9-10-F2 HMT125S6TFR8C-H9 NO AA-C

 

I'll try to replace memory and will write back.

Re: ProBook 4720s Keyboard problem

Hi, I'm using Ubuntu Lucid (latest) with BIOS F0C version. Seems, that this problem appears together with fan regulator. Fan sticks on the same sped for a long time, and together with high cpu load or heavy keyboard usage(typing text, coding) produces keyboard hanging. Please keep this topic updated. It's very important. More people will see this, most probably HP will handle this. Thanks, Sergei

Re: ProBook 4720s Keyboard problem

FYI: lucid isn't latest - there is new Maverick.

 

I gave it a try to chat with HP support referring to this new document: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c02717210&lang=en&cc=us&prodS...

 

Unfortunately this didn't give any result - support man asked all details then said it should be passed to (some) level 3 and gave me link where i can find local support. While local support knows nothing about the problem and want's me to bring it to them for time they will be able to diag it...i guess this is usual procedure...and this is dead circle since this is something that is really hard to diag because of no real regularity.

 

I hope while we keep writing here HP knows: the problem still appears.

Re: HP ProBook 4720s - Keyboard problem

Hi guys,

 

After installed new BIOS, laptop keyboard works perfect! It's already about 1 day of work and no problems, before it was few hours. Everything else works fine too. So, currently I'm very satisfied with that beta BIOS.

 

If someone wants to test it too, below is the link to download that BIOS:

Re: HP ProBook 4720s - Keyboard problem

Hi All,

If someone read this topic and still has the problem with keyboard, please download last BIOS version from official HP site, HP support already fixed that problem.

Try this link:

Re: HP ProBook 4720s - Keyboard problem

I have a Probook 6460b and I have the same problem.  facing it for 8 months now.

Sometime ago i called HP and they made me install some drivers.  After few days, the problem started recurring.

When you reboot the machine it works fine, and after some hours or days, the problem is back.  So right now, i just reboot and thats really annoying.

This is surely a problem with the firmware or drivers.  It is not easy to reproduce, some state (or combination of) is causing this issue, it surely happens, but we cannot identify the exact steps to reproduce. 

Since it is not straight foward to reproduce, it is upto HP to figure out and address this problem, else people who face issues will just tell others (which is what i would) about the issue and they will buy some other brand.

 

After going through the posts, I still dont see if there is a clear enough solution.

 

HP?   What do i do.

I would really appreciate a quick reply from HP on this.

 

This is frustrating a lot of users even within my company
